5。 According to the visual principle of frog eye, people have successfully developed an electronic frog eye. This kind of electronic frog's eyes can accurately identify objects with specific shapes like real frog's eyes. The anti-jamming ability of radar is greatly improved after the electronic frog eye is installed in the radar system. This radar system can quickly and accurately identify aircraft, ships and missiles with specific shapes. In particular, it can distinguish between true and false missiles and prevent the fake from confusing the real.
electronic frog eyes are also widely used in airports and traffic arteries. At the airport, it can monitor the take-off and landing of aircraft, and give an alarm in time if it is found that the aircraft is about to collide. On the main roads, it can direct the driving of vehicles and prevent vehicle collisions.
6。 According to the principle of bat ultrasonic locator, people also copied the "pathfinder" for the blind.

Japanese scientists have been inspired by ants foraging. They have developed a large-scale integrated circuit to simulate Qi Xin, a foraging ant, working together to carry food and continuously transmit information from the nearest "food source" to the "ant nest". According to this new information processing method, people are likely to develop a computer with a new calculation mode.
There are many inspirations that human beings can get from nature, such as imitating eggs. Inspired by the flight of birds, the airplane was invented. Cut one's finger from the thatch and invented the saw ... There are many animals and plants in nature with their own unique ways of life, which hint at the mysteries of nature.
There are many revelations from nature, among which one kind of snake is called rattlesnake, which has infrared eyes. Through this kind of snake eyes, human beings have developed a missile with rattlesnake-like eyes, and its name is called rattlesnake missile, because human beings. That's why it's called a rattlesnake missile.
Like a rattlesnake, a rattlesnake missile can accurately track the enemy with "hot eyes" until it is destroyed. Because the "hot eyes" of a rattlesnake judge the enemy's position according to the temperature of the enemy, the rattlesnake missile can accurately hit such things as airplanes, warships and tanks. The mobile low-altitude short-range all-weather ground-to-air missile developed by France is mainly used to deal with low altitude. In order to defend airports and ports, it can also be used to deal with cruise missiles. The missile is 2.94m long, with a diameter of .156m, a weight of 84.5kg, and a launcher length of 3.2m. The warhead is fragment-focused, with a total weight of 13.9kg and a killing radius of 6-8m. The power unit is a single-stage solid rocket engine, and the guidance mode is full-range radio command guidance, with an operational radius of 5-85m. The combat altitude is 5 ~ 3m. The missile has semi-cross-country maneuverability.
Colorful butterflies, such as Papilio japonica and Monarch butterflies with brown veins, especially Papilio fluorescens, whose hind wings are golden, green and blue in the sun. Scientists have brought great benefits to military defense by studying the color of butterflies. During World War II, German troops surrounded Lien. Trying to destroy its military targets and other defense facilities with bombers. According to the lack of understanding of camouflage at that time, the Soviet entomologist Schwanovich put forward the principle that the color of butterflies is not easy to be found in flowers, and covered the military facilities with butterfly-like camouflage. Therefore, despite the German army's efforts, the military base in Leningrad remained safe and sound, laying a solid foundation for winning the final victory. According to the same principle, Later, people also produced camouflage uniforms, which greatly reduced the casualties in the battle.
Honeycombs are composed of hexagonal small beehives arranged neatly, and the bottom of each small beehive is composed of three identical diamonds. These structures are exactly the same as those accurately calculated by modern mathematicians-the obtuse angle of the diamond is 19.28' and the acute angle is 7.32', which is the most material-saving structure with large capacity and extremely strong. Many experts are amazed. People imitate its structure and use various materials to make the honeycomb sandwich structure board, which has high strength and light weight and is not easy to conduct sound and heat. It is an ideal material for building and manufacturing space shuttles, spaceships, satellites, etc. Polarizers sensitive to the direction of polarized light are arranged adjacent to each eye of the compound eye of bees, which can be accurately positioned by the sun. Scientists have successfully developed a polarized light navigator based on this principle. It has long been widely used in navigation.
Dragonflies can generate local unstable airflow different from the surrounding atmosphere through wing vibration, and wells use the vortex generated by the airflow to lift themselves. Dragonflies can soar under a small thrust, not only flying forward, but also flying backward and left and right, with a forward flight speed of 72km/ h. In addition, the flying behavior of dragonflies is simple. Only two pairs of wings flap constantly. Scientists have successfully developed a helicopter based on this structural foundation. When the plane flies at high speed, it often causes violent vibration, and sometimes even breaks its wings, causing plane crashes. Dragonflies are safe when flying at high speed, so people follow the example of dragonflies and add balance weights to the wings of the plane to solve the thorny problem of vibration caused by high-speed flight.
The jumping ability of fleas is very high. Aviation experts have done a lot of research on this. Inspired by its vertical take-off, a British aircraft manufacturing company has successfully manufactured a harrier aircraft that can take off and land almost vertically. Modern television technology has created a large-screen color TV according to the structural characteristics of insects' single compound eyes, and can also combine small color TV screens into a large picture, and can frame some specific small pictures at any position on the same screen, which can not only broadcast the same picture. It can also broadcast different pictures. The multi-aperture optical system device successfully developed by scientists according to the structural characteristics of insect compound eyes is easier to find the target, and has been applied in some important weapon systems abroad. According to the principle of mutual inhibition between monocular eyes of some aquatic insects compound eyes, the lateral inhibition electronic model is made and used in various photographic systems. The photos taken can enhance the image edge contrast and highlight the outline, and can also be used to improve the display sensitivity of radar. It can also be used for the pretreatment of character and picture recognition system. The United States has developed an engineering model of terminal guidance seeker imitating insect compound eye search by using the processing information of insect compound eye and the principle of directional navigation. Japan has developed a new construction method of engineering machines and buildings such as hexapod robot by using insect morphology and characteristics.
From the seepage prevention of Yuanmingyuan lake to "man can conquer nature"
Recently, Yuanmingyuan has invested heavily in "laying the bottom of the lake". It has been explicitly opposed by many environmental protection experts and environmentalists. The reason of Yuanmingyuan Management Office is to prevent water leakage and save water charges. The main objections of environmental protection experts are as follows:
First, the anti-seepage project will block the last passage of more than 1 hectares of rainwater to the underground, and the ecological environment of more than 1 hectares of wetlands will be destroyed, losing the largest natural wetland in Haidian District of Beijing; Second, Yuanmingyuan Lake is an ecosystem, and a large number of microorganisms at the bottom of the water are silently responsible for inhaling carbon dioxide garbage and fish feces, recreating oxygen organic matter, so that the clear fish in the lake can swim happily; Now covered with plastic sheets will damage microbial activities, and the whole ecosystem will collapse. Eventually, the whole lake will become a stagnant pool, the river will stink in an all-round way, and the dead fish on the river will turn over, causing ecological catastrophe; Third, the practice of plugging the stone crevices completely destroys the original natural ecological balance, and the plants on the shore can only rely entirely on artificial watering in the future, which is not conducive to water saving.
When it comes to environmental protection, it immediately reminds us of the opposition between environmental protection and economic development, even if it is temporary. As for the "Seepage Prevention of Yuanmingyuan Lake" project, whoever believes that time is fair will have a public opinion several years later. The whole anti-seepage project at the bottom of the lake needs about 3 million yuan, and the annual water fee can be saved by more than 1 million yuan, and the cost can be recovered in three years. The seemingly simple economic account does not consider the ecological cost. The ecological cost may not have much to do with Yuanmingyuan itself, but it is related to the surrounding residents, and it is related to the ecological environment of the whole region, and even to the ecological environment of the whole city, the whole country and even the whole earth. amazon rain forest, Known as the lungs of the earth, if the lungs can't work effectively and normally to maintain the ecological balance of the whole earth, the consequences will be disastrous.
There are too many things that human beings can do, and it's not a problem to go to heaven. Human beings always have the inner impulse to conquer nature, and always think that "man can conquer nature", but the result is mostly punished by nature. Sanmenxia Hydropower Station is an extreme example; During the Cultural Revolution, artificial terraces were built all over the country, and farmland was reclaimed by water, and forests were destroyed to grow grain. There are countless examples of this violation of the laws of nature. What caused soil erosion and serious ecological imbalance in the end? Humans had to return farmland to forests, plant trees and grass in the desert, maintain the simple balance of nature, and seek their own survival.
With the progress and development of human science and technology, There are more and more ways for human beings to influence nature. Precipitation is less than artificial precipitation enhancement. Maybe one day, human beings can control the direction of clouds in the sky, and move the clouds wherever rain is needed, which is much more convenient and less costly than the "South-to-North Water Diversion" on the ground. If that day happens, it will pose a greater threat to human survival.
The greatest enemy of human beings is actually human beings. In order to lay more eggs. To satisfy human appetite more, human beings "invented" lean pigs fed with "meat-eating chicken", "duck-stuffing" and "lean meat". They ate too much meat, but what the meat they ate brought to human beings violated the laws of nature and was bound to be punished. This punishment may take decades and hundreds of years before it will appear.
Will it be human beings who will eventually destroy human beings? Or will it be? Balance. Being kind to nature means being kind to ourselves. Agree with 24| Comment 29-3-24 21:19 Snowy season G | Level 1
Enlightenment from nature
In ancient times, lightning burned the forest, and ancient people found that the food after the fire was more delicious than raw food, and the fire could keep warm; When two stones collide, they will produce sparks, so they learned to make a fire. Ancient people found that plants could grow when seeds fell into the ground, so they learned to farm. ..... Birds have wings to fly, so they invented airplanes; .......
The survival of human beings depends on nature, and the development of human beings is based on the revelation of nature. Without the revelation of nature, there would be no civilization as developed as human beings now!
