Popular Science | The updated version of COVID-19 Vaccination Essential Manual is coming!

COVID-19 vaccine must be.

One of the most talked-about topics in the whole country during this period!

From the meeting, "Did you eat?"

You can see it when you go to "Did you get the COVID-19 vaccine?"

This share of the national "vaccine fever" everyone

Making contributions to protecting the personal safety of oneself and others.

With the increasing number of people vaccinated, the focus of attention has also changed, especially for the necessity of the second injection, vaccination interval and so on. We have compiled some frequently asked questions to see if there is anything you want to know. If you have any other questions, you can also tell us in the message area, and we will reply you in time.

one

What is the vaccination procedure of COVID-19 vaccine?

A: At present, COVID-19 vaccine produced by Beijing Kexing Zhongwei Biotechnology Co., Ltd. and Wuhan Institute of Biological Products (Wuhan Institute) and Beijing Institute of Biological Products (Beijing Institute) under China Biological Co., Ltd. of Sinopharm Group is used in Shanghai.

The Technical Guide for Vaccination in Covid-19 (First Edition) issued by the National Health and Wellness Committee on March 29th, 2021 recommended that the vaccination interval of 2-needle basic immunization of inactivated vaccine in Covid-19 should be 3-8 weeks (21 days -56 days).

The three kinds of vaccines used in this city are inactivated vaccines, the production process is basically the same, and the vaccination procedures are the same. They are all vaccinated with 2 needles, with an interval of 3-8 weeks. The inoculation point will reasonably arrange the inoculation time of the second dose in this interval according to the supply of vaccine and the inoculation time of the first dose.

nine

After the first injection, there are other symptoms. Can I get a second injection?

A: We list several situations.

The first is that after vaccination, it happens to catch up with the onset of chronic diseases or suffer from acute diseases such as colds and herpes. For this kind of situation, the disease should be controlled and treated first, and the second injection can be continued after the attack period has passed or the control of chronic diseases has stabilized.

The second is the adverse reactions such as fever and slight rash after the first dose of inoculation. From the results of clinical trials of COVID-19 vaccine and the information collected during its use, the common adverse reactions of COVID-19 vaccine are basically similar to those of other vaccines that have been widely used. Mainly for the inoculation site redness, induration, pain, etc., but also fever, fatigue, nausea, headache, muscle pain and so on. Usually, this kind of reaction will disappear by itself with time, without special treatment, and the second injection can be inoculated as usual.

Of course, if there are serious allergic reactions after the first dose, such as acute allergic reactions, angioneurotic edema, dyspnea, etc., or other contraindications to vaccination, the second dose is not recommended.

Inoculation contraindications include:

(1) those who are allergic to the active ingredients of the vaccine, any kind of inactive ingredients, substances used in the production process, or those who have been allergic to similar vaccines before;

(2) Those who have had severe allergic reactions to vaccines in the past (such as acute allergic reactions, angioneurotic edema, dyspnea, etc.);

(3) Patients with uncontrolled epilepsy and other serious nervous system diseases (such as transverse myelitis, guillain-barre syndrome, demyelinating diseases, etc.);

(4) People who are suffering from fever, acute diseases, acute attacks of chronic diseases, or uncontrolled patients with severe chronic diseases;

(5) Pregnant women.

Of course, if you feel unsure whether your condition can be vaccinated, you can tell the doctor at the vaccination site truthfully and let the doctor at the scene judge.

10

Why are there rumors that the COVID-19 vaccine only works for a few months?

A: In March last year, some people, as the "vanguard" of vaccines, were vaccinated with inactivated vaccine from COVID-19, which is now on the market. Vaccine companies have carried out clinical monitoring. Up to now, they have obtained antibody detection data for more than 9 months, which shows that the antibody is still at a certain level, and will continue to strengthen monitoring to further observe the maintenance time of antibodies.

11

Can you call later?

A: Only when the vaccinated individuals reach a certain proportion can the protection of the population be formed, that is, the population immune barrier can be formed to protect individuals who cannot be vaccinated due to vaccination taboos and a few people who have not yet produced protection after vaccination. If everyone delays the vaccination, then the immune barrier will never be established. If everyone vaccinates quickly, this barrier may come one day earlier. To return to normal life as soon as possible, vaccine is the best choice at present.

twelve

How to inoculate COVID-19 vaccine for people with chronic diseases or colds?

A: 1. Can patients with hypertension be vaccinated?

① Patients with hypertension can be vaccinated if their blood pressure is lower than 140/90mmHg through lifestyle adjustment and/or drug treatment.

② Patients with hypertension can be vaccinated if their systolic blood pressure is ≥140mmHg and/or diastolic blood pressure is ≥90mmHg through lifestyle adjustment and/or drug treatment, but their systolic blood pressure is < <160mmHg and diastolic blood pressure is < <100mmHg on that day.

After vaccination, doctors in the observation area need to strengthen observation.

③ Patients with hypertension were given lifestyle adjustment and/or medication, but the systolic blood pressure was ≥160mmHg and/or the diastolic blood pressure was ≥100mmHg, so vaccination was suspended.

After adjusting the treatment plan of hypertension, vaccination can be carried out when the blood pressure is controlled at systolic pressure < <160mmHg and diastolic pressure < <100mmHg.

2. Can diabetics be vaccinated?

① Diabetes patients can be vaccinated if their fasting blood glucose is ≤13.9mmol/L through lifestyle adjustment and/or drug treatment.

② At present, diabetic patients with acute complications of diabetes (ketoacidosis, hyperosmotic state, lactic acidosis) or those who have recovered from the above acute complications for less than 2 weeks are suspended from vaccination.

③ All kinds of drugs (including insulin injection) used to treat diabetes are not taboo for vaccination.

3. Can patients with thyroid diseases be vaccinated?

① Patients with hypothyroidism who have been diagnosed and taken a stable dose of levothyroxine can be vaccinated.

② Taking levothyroxine (Eupatorium) or methimazole (Saizhi, Tabazol) or propylthiouracil, which is used to treat hypothyroidism, is not a taboo for vaccination.

③ When TSH>10μIU/mL, and T3 and T4 are lower than normal, the vaccination should be suspended.

④ Inoculation is suspended for patients with uncontrolled hyperthyroidism or hyperthyroid exophthalmos.

4. Can chronic gastritis be vaccinated?

Chronic gastritis is in the non-attack stage and can be vaccinated.

Patients with acute attack of chronic diseases or serious and uncontrolled chronic diseases cannot be vaccinated.

5, schizophrenia patients, the condition has been controlled, taking the lowest dose of drugs for a long time. Can I get COVID-19 vaccine?

Can be inoculated.

6. Can I get vaccinated if I have a bad cold?

Vaccination will be suspended during acute attack of gout, bad cold, myocardial infarction and cerebral infarction.

For fever (underarm temperature ≥37.3℃) caused by any reason (cold, wound infection and local inflammation), vaccination shall be suspended.

7. Can patients with heart disease and heart stents be vaccinated?

Diseases such as heart disease, coronary heart disease, coronary atherosclerosis, etc. are not acute attacks and can be vaccinated.

If it has been done for a long time and the physical indicators are stable, consider vaccination as appropriate after consulting the attending physician.

8. Do I need to get Covid-19 vaccine if I have been infected with Covid-19?

Existing research data show that reinfection is rare in Covid-19 within 6 months after infection. COVID-19 virus-infected people (patients or asymptomatic infected people) can receive one dose after 6 months on the basis of full notification.

9. How to judge whether to vaccinate other chronic diseases?

People with chronic diseases with stable health and good drug control should not be considered as the taboo population for vaccination in COVID-19, so vaccination is recommended.

Patients with acute attack of chronic diseases or serious and uncontrolled chronic diseases cannot be vaccinated.

Such as:

Chronic eczema has no obvious attack and can be vaccinated.

The current symptoms of chronic urticaria are not obvious and can be vaccinated.

The symptoms of chronic rhinitis are not obvious and can be vaccinated.

Chronic hepatitis does not need medication, and its liver function is normal, so it can be vaccinated.

Tuberculosis is not active and can be vaccinated.

Acute types such as non-pustular psoriasis can be inoculated.

Chronic obstructive pulmonary disease (COPD) in non-acute attack stage, no obvious cough and asthma, can be vaccinated.

Ankylosing spondylitis has no acute pain and can be vaccinated.

Depression drugs are well controlled, life and work are as usual, and you can be vaccinated.

Before and after operation, patients with malignant tumor are undergoing chemotherapy and radiotherapy, and vaccination is suspended.

The general principle of immune system diseases (systemic lupus erythematosus, rheumatoid arthritis, ankylosing spondylitis, Sjogren’s syndrome, etc.) is cautious vaccination. Generally speaking, COVID-19 inactivated vaccine and recombinant subunit vaccine can be vaccinated when the condition is stable.

After more than three years of malignant tumor surgery, radiotherapy and chemotherapy are no longer carried out; Nephrotic syndrome; Take immunosuppressive drugs after kidney transplantation; Aids patients and HIV-infected people are advised to be vaccinated with inactivated vaccine and recombinant subunit vaccine.

13

About drug users, how to get COVID-19 vaccine?

Answer: 1. Can I still take antihypertensive drugs after vaccination?

Sure.

2. How long does it take to take anti-inflammatory drugs to get a vaccine?

Theoretically, it doesn’t affect, but if you take antibiotics and anti-inflammatory drugs, it means that some diseases are in the onset period, so it is recommended to vaccinate after your body recovers.

3. Does it matter if patients with depression take medicine for a long time?

Depression drugs generally do not affect vaccination.

4. Can I be vaccinated when taking drugs with insufficient cerebral blood supply?

Can be inoculated.

5. Can I be vaccinated while taking immunosuppressants?

Consult a doctor about the metabolic cycle of the drug before making a judgment.

6. Symptoms such as colds and tonsillitis appear after vaccination. Can I take medicine?

Kim Jong-un watched the Air Force Flight Competition, and the North Korean Air Force rarely showed its family.

  The five major services of the Korean People’s Army have always been the object of external attention. Compared with the Korean People’s Army and other services that often appear, the appearance rate of the Korean People’s Army Air Force is very low. However, according to Korean Central News Agency’s report on November 16th, Kim Jong-un, Chairman of the Workers’ Party of Korea, Chairman of the State Council and Supreme Commander of the Armed Forces, watched the "Korean People’s Army Aviation and air defence forces Flight Commanders Combat Flight Technology Competition 2019". This event was initiated by Kim Jong-un five years ago, and it has also become a routine annual competition. Kim Jong-un hopes to further improve the flight skills and actual combat capabilities of flight commanders and combat pilots through competition competitions close to actual combat. Every flight competition, the top leader of North Korea will personally attend and give careful guidance. The purpose of this competition is to demonstrate the ability of air force fighters to destroy enemy targets and strike the ground. In this year’s air force flight competition, North Korea’s main model was publicly unveiled, and this mysterious air force once again entered the public eye.

On November 16, Kim Jong-un took a group photo with the flight controllers who participated in the combat flight technology competition and achieved results. MiG -29 appeared in the photo as the background.

  After observing, Kim Jong-un said that North Korean pilots should fight with enemies armed to the teeth with great ideas and tactics. The victory or defeat of a battle is not determined by the combat data of weapons and equipment, but depends on what ideas and why you fight. The enemy who flaunts his technical superiority cannot overwhelm the superiority of the Korean People’s Army soldiers in political thought and fighting morality. Kim Jong-un also put forward the development direction of air force to develop Korean-style aviation weapons and equipment and contain the enemy’s display of aircraft technical advantages, and put forward the programmatic task of strengthening and developing the main air force.

  As can be seen from the photos published by the official media of North Korea, MIG -29 is still the "apple of the eye" of the North Korean Air Force. Although the MIG -29 is designed to counter fighters including the American F-16, the backwardness of electronic equipment and other systems and short range have made it impossible to compete with its opponents. Previously, most of the upper parts of North Korea’s latest MiG -29 fighter were painted with dark green and the bottom was dark sky blue. At the end of January 2012, the MIG -29 was also shown in the commemorative photos taken by Kim Jong-un when he inspected the air force. From the sky, the color of the upper part of the plane is similar to that of the land, and from the ground up, the color of the bottom of the plane is similar to that of the blue sky, so the concealment performance of the plane is improved. In 2014, North Korea began to repaint the fighter plane, changing the original dark green on the upper part of the MIG -29 fighter plane into light gray with markings, which is what we see now.

  On April 17, 2014, Kim Jong-un inspected the Korean People’s Army Air Force and air defence forces’s No.1017th Army. He said that when he passed by the army, he made a surprise inspection to understand the flight training of fighter planes. At that time, Kim Jong-un also ordered the fighters on duty to take off and complete difficult and complicated air combat actions. The photo taken at that time was also based on MIG -29.

  According to South Korean media reports in 2015, although the fighter planes of the North Korean Air Force are not as advanced as those of the South Korean Army, their number is already twice that of South Korea, and some old fighters will still pose a threat to South Korea. North Korean leaders have always stressed the importance of air combat, but reports from the North Korean media show that the strategy of the North Korean Air Force seems to be developing in the direction of ground attack. The North Korean media reported that Kim Jong-un praised the North Korean pilot’s "spirit of suicide bombing" and his passionate patriotism.

An -2 transport aircraft

An -2 transport aircraft

  Korean media said that North Korea has 300 An -2 transport planes and called them "indigenous steelmaking-class" stealth aircraft. An -2 transport plane is a two-wing transport plane developed by the former Soviet Union in the last century. It is simple to manufacture and low in cost. It has been widely used for spraying pesticides. Because of its wooden fuselage and cloth skin, it is not easy to be found by the Korean Air Force radar once an attack is launched. The DPRK also painted stealth paint for it, and modified the electronic instrument panel. In 2014, it also dispatched more than 10 An -2 transport planes to hold an exercise of airborne troops attacking Incheon Airport at night. Korean media said that what worries South Korea even more is that the An -2 transport plane equipped with rocket launchers and the Il -28 bomber can attack South Korea’s Bering Island and Yeonpyeong Island within 2-3 minutes after taking off from the North Korean Air Force Base. The Korean army should be alert to North Korea’s air force.

  Compared with the Korean Air Force, which is equipped with a large number of third-generation aircraft, the old models of the Korean Air Force occupy the majority. The South Korean military even said, "Three days after the start of the war, South Korean fighters will be able to fly freely in North Korea’s airspace." Although the fighter plane has fallen far behind the times, the North Korean military’s flight contest may also be aimed at sending a signal to other countries, including the United States, that the Korean People’s Air Force is fully capable of defending the country.

  Two days after observing the Air Force Flight Competition, on November 18th, Kim Jong-un, Chairman of the Workers’ Party of Korea, Chairman of the State Council and Supreme Commander of the Armed Forces, instructed the Korean People’s Army Air Force and the air defence forces Sniper Division to conduct parachute training. According to Korean Central News Agency, Kim Jong-un instructed the training after receiving the report of the training plan from the observation center. Kim Jong-un said that the snipers landed very well. After receiving the sudden order, the brigade commander and the brigade political commissar took the lead and used their troops as gods. They personally led the troops to the front in strange areas, and their combat actions were very mature and impressive. They were all brave and reliable real soldiers. Kim Jong-un expressed great satisfaction with it.

How to solve the two "one kilometer" problems of science and technology innovation in Hangzhou universities

Some time ago, a media report triggered a heated discussion among the public-a university in Guangxi received 131 million yuan in research funding, implemented 862 research projects, and realized zero results transformation. The data comes from the list of the management and use of special funds of nine district-administered universities from 2020 to 2022 published by Guangxi Audit Office.

Hundreds of millions of scientific research funds, the conversion rate of results is 0? The huge digital contrast makes the topic of difficult transformation of scientific and technological achievements in China become the focus again.

What is behind the 0 conversion rate? For Hangzhou and universities, how to do a good job in accelerating the transformation of scientific and technological achievements?

How to calculate the account with a conversion rate of "0"

The low conversion rate of scientific research achievements has always been a "long-standing problem" in domestic universities.

Take the key output of scientific research and innovation "invention patent" as an example. According to China National Intellectual Property Administration’s Patent Investigation Report of China in 2022 (hereinafter referred to as "Report"), the implementation rate of invention patents in China universities is 16.9%, of which the industrialization rate is only 3.9%. According to a report in Beijing Daily, the conversion rate of American colleges and universities’ achievements is about 50% according to relevant research calculations. Compared with developed countries, there is still a lot of room for improvement in the ability to transform achievements in Chinese universities.

As far as the whole society is concerned, a report entitled "Analysis Report on the Transformation Prospect of Scientific and Technological Achievements in Strategic Emerging Industries" shows that only 10%-30% of China’s cutting-edge scientific and technological achievements have been applied to actual production, and only 20% of them can truly form industries. The report pointed out that in the transformation of scientific and technological achievements, the institutional and institutional obstacles of "what to turn", "how to turn" and "who will turn" still exist.

The conversion rate of scientific research achievements is 0, does it mean that the scientific research funds hit Shui Piao?

Deng Haijian, chief expert of the network education teacher studio of the Ministry of Education of Hangzhou Dianzi University, thinks that it should be dialectically viewed from three levels.

From the total amount, 131 million yuan is indeed a large number, but it is spread evenly over 862 projects, with an average of only 150,000 yuan per project. Therefore, it is inevitable that some people will vomit. These expenses may not be enough for scientific research. How to realize the transformation of results? "Of course, the accounts are not calculated in this way. The projects are heavy and light, and the budget is large and small. What we have to focus on are those projects that should have been transformed but the results have not been transformed."

Judging from the standard of measuring scientific research work in colleges and universities, the conversion rate of achievements is not the only standard. There are many kinds of scientific research, which can be divided into basic research, application, technology development and so on. "Basic research is not about transformation, or it can’t be considered by transformation. Therefore, when evaluating scientific research, it is necessary to classify and analyze specific problems. What needs serious accountability should be a project that was originally directed at transformation, but the result was to fish in troubled waters. "

Deng Haijian feels that from the perspective of researchers themselves, we must be highly alert to this set of figures. "The urgent task is to do pragmatic scientific research, not to do scientific research for scientific research, or to do scientific research for topics, but to do more scientific research projects closely related to people’s lives and production."

The road to science and technology innovation in colleges and universities is difficult in two key "one kilometer"

What are the reasons why scientific and technological achievements are difficult to get out of the ivory tower? Perhaps it can be analyzed from the relationship between "scientific research", "scientific and technological innovation" and "innovation and entrepreneurship"

Professor Zhang Yu, Executive Dean of School of Life and Health Sciences, Hangzhou Institute of Advanced Studies, University of Chinese Academy of Sciences (Hangzhou High Court, National University of Science and Technology), has been deeply involved in scientific research for many years. In her view, the whole science and technology innovation chain can be compared to three stages-

"Scientific research" is like a process from 0 to 1, "scientific and technological innovation" is from 1 to 100, and "innovation and entrepreneurship" is constantly expanding from 100 to 10000. On the surface, the whole process seems to be the relationship between "scientific research" at the forefront and "innovation and entrepreneurship" at the end, which is separate. "But to maintain a long-term virtuous circle, the whole chain is mutually reinforcing, and all three links are inseparable from the practical exploration of related industries."

Zhang Yu’s point of view has been recognized by another senior researcher, Professor Yang Wei, Dean of the Institute of Basic Medical Innovation of Zhejiang University. He vividly compared the relationship between the three to three intertwined rings. "The three overlap and influence each other. It is not so much a science and technology chain, but actually more like a Ke Zhang network. A net, a chess game, a careless game will lose. "

If the relationship between the three is clarified, the crux can be found.

During the two sessions of the National People’s Congress this year, "scientific research" was frequently mentioned and became a hot topic. Liu Qiang, member of Chinese People’s Political Consultative Conference and member of the Standing Committee of 301 Science and Technology Committees of China Academy of Aerospace Science and Technology, said: "China’s scientific and technological circles are facing a relatively prominent common problem, that is, the original and leading scientific and technological research results are insufficient."

The source innovation ability is insufficient, and the "from 0 to 1" is lacking. The "first mile" on Kechuang Road has a difficult start. This difficulty also makes other institutions and units in the chain feel helpless. In a media interview, Hu Xiaowei, general manager of Paifu Intellectual Property Investment and Operation Company, pointed out: "There may be hundreds of colleges and universities working on the same subject and in the same direction, but the things they make are very general. The source is not good, how to transform it? "

Not only that, but the "last mile" problem on Kechuang Road has attracted more and more attention. Academician Shi Yigong, President of West Lake University, once said to the media: "The last straw to crush camels is to encourage scientists to start businesses."

It is understood that technology transfer and transformation needs compound professionals with backgrounds in intellectual property, law, management and industry, but there has been a lack of professionals and service institutions in this field in China. Colleges and universities are subject to institutional mechanisms and lack such talents. Most colleges and universities are responsible for transfer and transformation management, and most of them are part-time.

Will this source innovation incubation model bring "ice-breaking" effect?

Faced with the "two kilometers" problem, some forces are seeking a breakthrough.

In 2019, a brand-new innovative incubation model of medicine source was born in the Institute of Basic Medical Innovation of Zhejiang University. The Institute, jointly established by Zhejiang University and Hangzhou Linping Economic and Technological Development Zone, is an innovative platform led by basic medical disciplines and aimed at transforming the source of high-level original academic achievements.

Dean Yang Wei introduced that under the pressure of "generic drugs come quickly", "follow-up innovation" and "lack of innovative drugs with the first target", the institute focused on the field of biomedical source innovation and strived to incubate several innovative drugs and new medical devices with the first target in the world in China.

In other words, the first thing that the institute solves is the "first mile" problem of medical innovation. Therefore, a special incubation fund for innovative medicine is set up every year to collect high-level research results with transformation value for universities, scientific research institutions and medical institutions. At present, four rounds of global solicitation for innovative scientific research projects have been completed, and more than 100 million yuan of incubation funds have been invested to provide industrial incubation funds for more than 50 selected projects from Peking University, Zhejiang University, Xiamen University and China Pharmaceutical University. "Even if the result is only a paper, as long as it has the value of medical innovation and transformation, we are willing to give it the first bucket of help." Yang Wei told reporters.

In the "last mile" of the transformation of scientific research achievements, the institute also provided a new model-the "housekeeper" of the whole project. To put it simply, it is to let "professionals do professional things" and equip each project with a project management team, which is composed of project leaders, project management department personnel and industry experts in related fields, to control the progress of project implementation throughout the process and provide multi-level and three-dimensional results transformation services such as intellectual property consultation, commercialization strategy, project investment and financing docking, cooperation and docking of pharmaceutical companies, and assisting enterprises in industrial and commercial registration. At present, the Institute has successfully landed nine funded projects in project companies, and is promoting the incubation in a market-oriented way, and it is expected that 8-9 will land in the near future.

The reporter learned that among the top 50 universities that have entered the contract value of scientific and technological achievements transformation for five consecutive years, Zhejiang University has always ranked second in the country. Linping District regards biomedicine as one of the three leading industries and anchors the goal of "80 billion biomedical industry cluster". "Our ultimate goal is to become a world-class platform for incubating the results of medical sources, incubating the world’s first innovative target drugs for major disease interventions, medical devices and diagnostic products with independent property rights, helping the high-quality development of Linping biomedical industry and contributing to Zhejiang’s biomedical industry highland." Yang Wei also expressed the hope that the incubation model of the research institute can play more exemplary and leading roles in the innovation field of domestic pharmaceutical sources.

DJI came to the conclusion through experiments that, even if the safety blade passes through an object during flight, it will generally only leave a scratch, and it will not be directly split. But even so, it is not recommended that you try, which may cause a bomber or your own safety hazards.

Fast charging charger of DJI Mavic 3 Classic

The battery of DJI Mavic 3 Classic, like Mavic 3, has the capacity of 5000mAh and 77Wh, and the voltage is 15.4V. This battery provides the longest battery life of 46 minutes and the longest cruising range of up to 30 kilometers.

In addition, DJI Mavic 3 Classic is equipped with a GaN (gallium nitride) fast charging charger with a power of 65W, which is compatible with PD protocol. Besides charging the battery of DJI Mavic 3 Classic, it can also charge laptops, cameras and other devices.

Image system: 4/3 format Hasselblad camera is very powerful.

DJI Mavic 3 Classic inherits the design of this series of 4/3 format Hasselblad lenses, with 20 million pixels, equivalent to 24mm focal length and aperture range F2.8-F11. The 4/3 frame is what we often call M4/3 frame. However, in order to meet the take-off weight and size requirements of UAV, DJI and Hasselblad jointly developed a brand-new design.

That is to say, this lightweight and compact UAV lens can not only meet the requirements of image quality and resolution of 4/3 frames, but also meet the requirements of size, weight and power consumption required by DJI Mavic 3 Classic.

4/3 frame is the largest sensor size of consumer UAV at present. As the saying goes, the bottom is the first step to crush people. Thanks to the CMOS sensor with the bottom, DJI Mavic 3 Classic can bring excellent photography and video capabilities, not only better dynamic range performance, but also better color performance and resolution.

At the same time, in the dark environment, 4/3 frame can bring better noise suppression effect and make our dark video picture more pure. The newly added night video, cruise control and other functions can better serve users, so that users who have just stepped into photography can easily complete the shooting of various styles of videos.

The video specification of DJI Mavic 3 Classic also inherits the strength of Mavic 3 family, and supports the video specification of up to 5.1K 50P, and also supports the slow-motion video capture of 4K 120P. DJI Mavic 3 Classic supports 10-bit D-log, which provides a foundation for our later stage and color matching space. Supporting Hasselblad Natural Color Solution (HNCS) can make its color effect even better.

Through the video, we can easily understand the core competitiveness brought by the 4/3 format Hasselblad camera. Video is not only rich in details, but also remarkable in color expression, which can restore natural colors very accurately, as if it were the color appearance of the real world seen by our naked eyes.

In addition, the video itself has a dynamic range of 12.8 files, which is very helpful for later repair and adjustment. That is to say, with the help of DJI Mavic 3 Classic, we can shoot professional-grade videos, which can be used for video production in professional fields.

In terms of focusing, the experience effect of DJI Mavic 3 Classic is the same as that of DJI Mavic 3, and the focusing experience is excellent, just like we are using the camera’s focusing system. For users, it is more reassuring to hand over the focus to DJI Mavic 3 Classic to complete it by themselves.

In the photo section, we can see that the performance of DJI Mavic 3 Classic is still remarkable. After all, it is a 20-megapixel M4/3 format camera that can fly to the sky. 20 million pixels is close to the mainstream pixel specifications of the current camera, so the photos brought by DJI Mavic 3 Classic have delicate analytical performance, which can present the details clearly and completely.

The 12-bit RAW format file provides a very large space for our later period, which can make the photos more professional. When you encounter good scenery, you can use this 4/3 format Hasselblad camera to take pictures.

Obstacle avoidance: You can fly safely by avoiding obstacles in all directions.

When Mavic 3 in DJI was launched, an upgrade that surprised users was its obstacle avoidance system, and DJI Mavic 3 Classic completely inherited this obstacle avoidance capability. In other words, DJI Mavic 3 Classic supports omni-directional obstacle avoidance capability, which is the best performance of consumer drones in obstacle avoidance at present.

What is omni-directional obstacle avoidance, that is, DJI Mavic 3 Classic can sense the 360-degree spherical range of the whole body. We often say that up, down, front, back, left and right can avoid obstacles in these directions.

DJI Mavic 3 Classic’s down-looking obstacle avoidance vision sensor, ToF ranging sensor and fill light.

DJI Mavic 3 Classic has designed eight vision sensors, including two fisheye cameras at the front, back and bottom, which provide a 185-degree viewing angle and can cover a wider visual area. There are also two wide-angle cameras at the top of the fuselage, and there are ToF ranging sensors and fill lights below. Together, these designs provide powerful hardware support for obstacle avoidance vision.

In terms of software, DJI Mavic 3 Classic supports APAS 5.0 obstacle avoidance system. Thanks to the improvement of system algorithm, it can help DJI Mavic 3 Classic to avoid obstacles faster, more dexterous and smarter, and ensure the UAV to fly and take aerial photos safely.

When flying, DJI Mavic 3 Classic can identify obstacles and avoid obstacles by itself, even if it only makes the plane fly forward. We can choose emergency stop or detour in the menu, and detour can also choose safe or radical, which has achieved different results. No one will take corresponding measures to avoid obstacles according to our choice.

With excellent obstacle avoidance ability, it can bring excellent intelligent following ability to users. When we are outdoors, whether we let DJI Mavic 3 Classic follow our own walking and running shooting, or follow our own riding and driving shooting, we need the powerful following ability and obstacle avoidance ability of the drone to work together.

The overall performance of DJI Mavic 3 Classic is excellent. Because its obstacle avoidance system is smarter, it will have better path planning when following, and at the same time, its recognition ability is more stable, and it can keep up and keep up well.

Return flight: advanced intelligent return flight efficiency

DJI Mavic 3 Classic also has advanced intelligent return function. In the past, the unmanned aerial vehicle (UAV) was very unwise to return home. It needed to fly to a preset altitude, then fly back to the take-off point, and then descend. If you encounter a tall obstacle in the middle, you need to continue to climb the height and then cross the obstacle, which is time-consuming and electricity-consuming. Therefore, when we experience aerial photography, we will reserve enough power for the drone for returning flight. In this way, our experience time of aerial photography and flight will be greatly reduced.

DJI Mavic 3 Classic’s return flight ability is more intelligent and fully inherits the new skills of Mavic 3 family. During the flight, the visual processing engine of DJI Mavic 3 Classic can scan the surrounding environment in real time and build a three-dimensional environmental map. In this way, when returning, the drone will find a safe and efficient path to return.

If we return in the wild, the performance of DJI Mavic 3 Classic will not be particularly outstanding. After all, there are not too many obstacles in the wild to prevent us from returning. If you are returning in a city, especially in a city with many high-rise buildings, the intelligent return performance of DJI Mavic 3 Classic can be revealed. When encountering a tall obstacle, the drone does not climb or leap, but cleverly bypasses the obstacle and continues to return, which can save a lot of return time and electricity, and let us have more time to experience flying and aerial photography.

Image transmission: the picture is clear and stable.

The evaluation product we got this time is the remote control version of DJI Mavic 3 Classic RC, which means we got the remote control version with screen. However, both the remote controller DJI RC with screen and the remote controller DJI RC-N1 without screen have the same image transmission ability. DJI Mavic 3 Classic supports DJI O3+ image transmission, and can support the image transmission distance of up to 15 kilometers, and the transmitted images reach 1080P 60fps.

With this set of graphic transmission system, the experience of our daily use of DJI Mavic 3 Classic is directly improved. The first is the improvement of the picture transmission. The picture of 1080P 60fps is not only clear but also very smooth, which allows us to better view the flight picture and control the composition and flight. Although it is impossible to reach the image transmission distance of 15 kilometers in a city with serious interference, this image transmission system is still very stable and can ensure our safe flight experience. Even if it is disconnected, the plane can return intelligently, so don’t worry too much.

Endurance: 46 minutes can be a happy aerial photography.

The endurance of DJI Mavic 3 Classic is also 46 minutes, which is consistent with the products of Mavic 3 family. The test version we get will contain a battery itself, as well as two extra batteries in the battery pack and the charging housekeeper, which will ensure that we have a long flight experience and aerial photography time. At present, the 46-minute battery life ranks second among the consumer-grade UAVs in DJI, and the first one is the 47-minute battery life of the Mini 3 Pro with long battery life.

Battery and charging housekeeper of DJI Mavic 3 Classic

In the past, the average battery life of consumer-grade UAV products in DJI was around 31 minutes. Suppose we fly for 31 minutes, excluding the take-off, composition and adjustment time, which is about 10 minutes, and excluding the return time of about 6 minutes, our actual shooting time is only 15 minutes. The battery life of DJI Mavic 3 Classic is 46 minutes, so the actual shooting time can reach 30 minutes.

Summary: cost-effective flagship consumer drone

So far, our evaluation and introduction of DJI Mavic 3 Classic has come to an end. DJI Mavic 3 Classic has the same flying ability, obstacle avoidance ability, image transmission ability, endurance and so on as the consumer flagship drone DJI Mavic 3. At the same time, it also has a Hasselblad camera with 4/3 frame, which provides professional-grade imaging ability. The only difference is the telephoto camera. Of course, DJI Mavic 3 Classic has many functions that serve users, such as time-lapse photography, focus following, master shots, etc. Because these functions are completely consistent with the performance of Mavic 3, we will not repeat the test and introduction.

DJI's new UAV Mavic 3 Classic evaluation: more cost-effective.

DJI Mavic 3 Classic is a differentiated Mavic 3 family member.

Consumer vouchers show a "multiplier effect". Hangzhou has driven consumption by nearly one billion yuan in six days.

  Hangzhou announced today that on the basis of the previous first coupon, an additional 150 million yuan will be issued for the second coupon. The coupons for this issue will be distributed from 10: 00 am on April 3, and consumers can participate in the coupon collection activities from the entrance of Alipay homepage or by searching for "Hangzhou".

  There are 1.5 million additional coupons for the second phase, each of which includes 3 coupons for 45 yuan, 35 yuan and 20 yuan. Direct deduction of cash use through Alipay when paying offline at designated merchants, valid for 7 days. Users who have received the first coupon can also apply again.

  In the past few days, consumer vouchers have become the most popular keyword in Hangzhou except the epidemic, and they are also like a needle catalyst, igniting the enthusiasm of offline consumption in Hangzhou’s "post-epidemic era". In Hangzhou Century Lianhua No.1 Supermarket, the store was crowded with orderly consumers, and there was a long queue in front of the checkout counter. Ms. Wang, a citizen, received a coupon from 50 yuan the day before. "Milk, meat, eggs, and many daily necessities, most of them were originally bought. With the coupon, you can just buy more."

  Wu Jingli of Century Lianhua Qingchun Store said that many customers come with coupons, and under the incentive of coupons, they can obviously feel the rebound of passenger flow.

  It is reported that in the three days from March 27 to 29, the sales of Century Lianhua in Hangzhou exceeded 60 million yuan. "Coupons have boosted the sales of high-end aquatic products, beef, etc., and the increase in turnover is very obvious."

  Snack bars, supermarkets, shopping malls, gas stations &hellip; &hellip; Consumer vouchers have boosted consumption, and they can be seen in almost every field of living consumption in Hangzhou. More than 10,000 pieces of Hangzhou "Xianfeng Fruit" were written off on March 27th, the first issue, and the customer unit price increased from 30 yuan to 70 yuan. Joe Doo, the person in charge of the operation, said that as of March 29th, their store had written off more than 30,000 copies.

  Hangzhou Yonghui Supermarket also ushered in a business peak because of coupons. Jiang Yajing, head of Hangzhou regional brand of Yonghui Supermarket, said that after the issuance of consumer vouchers, the daily passenger flow of the supermarket exceeded 6,000, an increase of about 70% compared with last week. On the 27th, the number of customers who paid through Alipay transactions increased by nearly 100% compared with the previous day.

  Consumer vouchers undoubtedly played the role of a catalyst, so that the consumption power that was originally suppressed by the epidemic rose rapidly. According to the data of Hangzhou Bureau of Commerce, from the issuance of the first coupon on March 27 to 16:30 on April 1, the government subsidy of 66.95 million yuan has been paid, driving Hangzhou to spend 949 million yuan.

  Wang Jianming, dean of the School of Business Administration, Zhejiang University of Finance and Economics, believes that guiding the consumption direction, adjusting the consumption structure, and promoting the consumption upgrade, the "leverage effect" of consumer vouchers has achieved the greatest economic benefits in the most effective way.

  Sun Hao, a teacher at the School of Economics of Zhejiang Gongshang University, also believes that the "multiplier effect" of the expansion of consumer vouchers will help to activate and release the consumer demand suppressed by the epidemic, boost consumption and promote the economy.

  Since March, in addition to Hangzhou, governments in Guangxi, Nanjing, Hefei and other places have issued consumer vouchers through platforms such as Alipay. Jiaxing announced the issuance of 200 million yuan of consumer vouchers; Shaoxing will carry out nine consumption promotion actions and distribute 180 million yuan coupons to the public; Ningbo, county (city) governments and enterprises will jointly launch 100 million yuan of cultural and tourism vouchers for benefiting the people. The Zhejiang Provincial Department of Culture and Tourism said that through the linkage of provinces, cities and counties, a total of 1 billion yuan worth of travel coupons and 100 million yuan worth of travel coupons will be launched.

  "Promotion fees and expanding domestic demand are a lasting battle." Many experts have reminded that as a short-term emergency policy and means, consumer vouchers have a certain effect on stimulating the economy, especially consumption, but they will not play a long-term role. To really stimulate domestic demand, only by enhancing residents’ consumption confidence and ability, increasing residents’ income and reducing the national burden, "comprehensive measures and stabilizing consumption expectations can people really consume, be willing to consume and dare to consume."
