Summer raising bee four points
In conclusion, we should correctly know about the 4K and the resolution, and choose the most suitable resolution when we buy a electric device, the DVR, the security monitoring device or something.

First, the use of high-quality new king spawning, expanding the egg ring, accelerate the breeding of new bees.
Secondly, the bee farm should select places where there is air circulation and shade, or cover the beech curtains on the beehive to prevent the sun from increasing the nest temperature and disturbing the bee colony; enlarge the nest door so that the air in the box is circulated and the weather is overheated. , Can be sprayed with cold water outside the box, feeding cold water; on crowded bee colonies, early addition of the box, increase empty nest and nest base frame, expand the hive; the use of young bees to produce royal jelly.
Third, prevent pesticide poisoning. In the summer season, the farmland is sprayed frequently and it is necessary to control the bees out of the nest. If poisoning is detected, the poisonous feed on the nest can be eliminated first, and then the thin honey or liquorice soup with 1:4 honey and water can be fed; Organophosphorus poisoning should also be treated with atropine, with 0.3 kilograms of honey water, mixed with 1% atropine sulfate 2 ml, directly sprayed on the bees, so that the bees suck each other to achieve the purpose of rescue.
Fourth, insist on prize feeding. In order to stimulate the enthusiasm of queen bee spawning and worker bee parenting, bees should be fed with thin syrup whenever the weather turns cooler each evening. In order to prevent the bees from alerting when feeding, the self-made rectangular shallow dish can be fed into the box. If there is not enough feed in the nest, feed it with concentrated syrup and feed it on a daily basis.
So what does 4K resolution mean?
In the digital technology field, people usually use the binary operations and the pixels to describe the size of the digital image. Due to the huge number of pixels that make up a digital image, the digital image size is usually represented by K. The 10th power of 2 is 1024, so: 1K=2^10=1024, 2K=2^11=2048, 4K=2^12=4096. How many 1024 pixels there are in the horizontal direction means how many K a video includes. Specifically speaking, for example, the resolution 2048×1080, 2048 represents the number of pixels in the horizontal direction and 1080 represents the number of pixels in the vertical direction; similarly, when the resolution is 4096×2160, 4096 represents the number of pixels in the horizontal direction, and 2160 represents the number of pixels in the vertical direction. In the actual production of alphanumeric version and digital projection, the number of pixels in the horizontal or vertical direction of the image needs to be adjusted according to different aspect ratios. Therefore, the resolution of 8847360 pixels close to the 4K image can also be called the 4K such as the resolution 3840*2160 which is common on the market. And strictly speaking, the standard 4K resolution is exactly 4 times the number of pixels of the 2K resolution 2048×1080, and 16 times the number of pixels of the 1K resolution 1024×540.
4K resolution belongs to the Ultra HD resolution, which means that the audience will be able to see every detail and close-up in the photos/videos at this 4K resolution. If 4K resolution is applied to the cinema, the audiencescan cearly see every detail and close-up of the film whichever cornor of the cinema they are at.
4K resolution refers to that the pixel value per line in the horizontal direction reaches or approaches 4096, regardless of the aspect ratio. 4K resolution also has a variety of derivative resolutions, such as the Full Aperture 4K(4096*3112), the Academy 4K(3656*2664), and the UHDTV 4K(3840*2160), etc.,. And in the security and protection field, when we mention the 4K resolution, it refers to 3860*2160, 800W pixels.
4K resolution fits the resolution standard of the new generation of the Hollywood blockbusters. Different from both the so-called high-definition TV (1920×1080 resolution)that we watch at home and the large 2K resolution screen (2048×1080 resolution) of the traditional digital cinema, the 4K resolution means the ultra-high resolution video of the 4096×2160 resolution. The traditional high-definition TV shows the video of 2.07 million pixels, the traditional digital cinema shows the video of 2.21 million pixels, while the 4096×2160 resolution theater can show the high-definition video of 8.85 million pixels.
