"Difficult to see a doctor, expensive to see a doctor" has always been a major problem affecting the development of China's medical industry . The uneven distribution of medical resources has caused the imbalance between supply and demand, which is the main cause of this problem. People are going to the big cities and large hospitals for medical treatment. Currently, only like 120,999 and other first-aid services provide on-site services; some communities also have “film medical consultations†– only when patients have special needs, the local community hospitals will visit the patients’ homes for medical practice. These are the medical industry in China. Severe test. ·Policy support, multi-point practice becomes possible In recent years, modern medical methods such as mobile medical care , mobile phone consultation, and telemedicine have alleviated the situation of “not getting sickâ€, but they are still not optimized medical solutions. Until November, the National Health and Family Planning Commission issued the "Physician Practice Registration Management (Consultation Draft)" public consultation, clearly encourage doctors to practice more, in order to promote the flow of doctor resources, help to solve the shortage of medical resources in some areas. problem. The promulgation of the "Measures" has solved many problems brought about by the practice of doctors' multi-point practice, allowing doctors to use their spare time to increase their income both formal and confident, and encourage more experts from large hospitals to go to grassroots institutions to facilitate patients. Seek medical attention at the door of the house, so that quality medical resources are closer to patients. ·Industry pioneer, multi-point practice successfully landed The New Deal encourages qualified and competent doctors to carry out multi-point practice, paving the way for the development of such organizations as the Doctors Group. Bode Jialian Medical Group (hereinafter referred to as “Bodejialianâ€) successfully practiced doctors' multi-point practice, and quickly became the leader of the industry with keen business insight and strong strength. Bodejialian was established in Shenzhen in March this year. The founder is well-known Lin Feng and Dr. Xie Yushi. He is the first doctor in China to have his own practice standards, quality and risk control system, and registered as a business person. group. At Bodejialian, experts will sign a contract to the doctors' group to provide valuable medical services, breaking the restrictions that experts have only practiced at the first practice point. This move can not provide the market with a variety of quality medical services, but also enable the doctor's professional value to be reflected in the reasonable sunshine, and promote the sound and rapid development of the medical community. At present, Bodg Jialian has more than 300 experts signed through a multi-point practice model, covering 26 majors such as gastrointestinal surgery, hepatobiliary surgery and congenital heart disease. At the same time, Bodejialian also opened a handheld hospital, using Internet technology and platform to carry out the "expert-driven grading diagnosis and treatment" project, which not only allows the citizens of Shenzhen to enjoy the famous doctors' services throughout the doctor's group at their doorstep. It is also possible to sink the wisdom of famous doctors to the grassroots level, so that grassroots doctors can improve their professional quality, continue to receive continuing education, and allow grassroots people to enjoy higher quality medical services. Recently, Bodejialian announced a strategic cooperation with China's health care service Internet leading enterprise health road, the two sides will jointly launch a comprehensive "Traditional Medical Doctor", "Healthy Butler", "Family Doctor", etc. Medical service products, on the basis of reflecting the professional value of doctors, form an efficient expert-driven grading diagnosis and treatment model to achieve a win-win situation for doctors, patients, hospitals and enterprises.

Lamp panel
The lamp panel is divided into ordinary infrared lamps (Dingyuan and Guanglei) and array lamps. The array camera is also divided into 1W, 2W and 3W. Therefore, when choosing infrared lamps, if it is an ordinary infrared lamp, try to choose Dingyuan and 3W array lamps. Since the appearance of infrared lamps is generally invisible, some cottage cameras are filled with Guanglei and 1W array cameras are filled with 3W array cameras. Therefore, try to choose a large brand when choosing cameras.
Maximum Aperture
The real value of the maximum aperture is to improve the light intake under low light conditions, so as to achieve the best exposure combination. In general, the ability to visualize the lens is not required for shooting landscapes. In addition, the lens caliber is not required for shooting landscapes except in particularly dark places. However, when the 70-200mm zoom lens is equipped with a 2-fold zoom lens to make the telephoto section become 400mm and AF is used for automatic focusing, it is better to choose a lens with the largest aperture of F2.8. Large aperture is conducive to accurate focusing in dark conditions. When shooting people with a large aperture lens, even in places where the light is weak, the handset can also use natural light to shoot. In addition, the lens with the largest aperture can bring fast shutter speed, so sports photography also needs a large aperture lens.
Another reason for requiring the lens aperture to be large is to be able to visualize the background freely and ensure the quality of visualization. When the aperture of the lens with the maximum aperture of F1.4 is reduced to F2, both the imaging quality and the blurring quality of the background are better than those of the lens with the maximum aperture of F2. Therefore, it is of great value to reduce the aperture of a large aperture lens by one stop. Any photographer should be good at using the lens.
focal length
The first thing to pay attention to when selecting a lens is the focal length of the lens. In fact, focal length is a matter of perspective. Different focal lengths and perspectives are different. In addition, users should be clear about what is the main purpose of buying lenses? Is it for scenery or people. As we all know, it is better to use a wide-angle lens when shooting landscapes, and a telescopic lens when shooting people. Therefore, you should first decide the focal length of the lens you want to buy according to the purpose of photography.
The best focal sections for shooting scenery are 24 mm wide angle focal section and 200 mm telescopic focal section (both are based on 35 mm specifications, the same below). When the wide-angle focus segment of the standard zoom lens evolves from 28mm to 24mm, the viewing angle becomes larger, and the range of scenery that can be stored is greatly expanded. Generally speaking, the maximum aperture of the lens is not required for shooting landscapes. If you are mainly shooting landscapes, a wide angle focal length of 24mm is basically enough when you select a zoom lens. As for the telephoto section, it must be at least 200mm. If the telephoto section is 300mm or 400mm, it is more ideal, and the degree of freedom will be greatly improved. The telephoto focus segment of traditional zoom lens is 300 mm, which is 450 mm for digital SLR. The focal length has been expanded by 1.5 times, which makes it more enjoyable to use. This is the value of digital SLR. The wide-angle focal section of the digital special ultra wide-angle lens produced is generally 12mm, equivalent to 18mm of 35mm, which is nearly 1.5 times larger than the 28mm focal section of 35mm, thus greatly widening the left and right range of the scenic scene.
The best focal length for shooting people is 85mm. In terms of 35mm standard, 85mm focal length is basically used as the standard for shooting characters. The portrait taken by the 85mm focal section is basically close to the picture effect taken by the medium frame camera. It is not only suitable for the distance, but also the face of the person looks very natural. The distance between the camera and the person being photographed can basically be kept at the normal speaking distance. The 85mm focal length can also effectively blur the background and prominent characters. In order to obtain good visualization effect, the lens with the largest aperture should be selected. The 85mm focal length is about 135mm on the digital SLR. Although the sense of distance of the shot is a little weak, it is basically OK, so the focal length of the person lens should be at least about 85mm.
A 100mm macro lens is enough for traditional SLR to shoot flowers. The 100mm macro lens can be used for equal magnification photography, which can make the flowers very large. However, when taking equal magnification photography or near equal magnification photography, due to the depth of the long focus scene, it is easy to shake, so anti shake measures should be considered when taking photos. From this point of view, 50mm macro lens is easier to use on digital SLR.
