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. After installing electronic frog eyes in radar system, the anti-jamming ability of radar is greatly improved. 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 false confusion.
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 call the police in time if it is found that the aircraft is about to collide. On the main road, you can direct the vehicles to prevent them from colliding.
6。 According to the principle of bat ultrasonic locator, people also copied "Pathfinder" for the blind.

Japanese scientists were inspired by ants foraging. They developed a large-scale integrated circuit to simulate the foraging ants Qixin carrying food together and sending information from the nearest "food source" to the "ant nest" in sequence. According to this new information processing method, it is possible for people to develop a computer with a new computing mode.
There are still many inspirations from nature, such as: imitating the characteristics of egg shape and building arch bridges; Inspired by the flight of birds, people invented airplanes. I cut off my fingers from the thatch and invented the saw ... There are many animals and plants in nature, which hint at the mysteries of nature in their own unique way of life.
There are many inspirations from nature. There is a kind of snake called rattlesnake. It has an infrared eye. Through the eyes of this snake, human beings have developed a missile with eyes like rattlesnakes. Its name is rattlesnake missile, so it is named rattlesnake missile, because humans are made according to the eyes of rattlesnakes.
Sidewinder missiles, like rattlesnakes, can accurately track the enemy with "hot eyes" until they are destroyed. Because the "hot eye" of the rattlesnake judges the position of the enemy according to its temperature, the rattlesnake missile can accurately hit planes, warships, tanks and the like. The mobile low-altitude short-range all-weather ground-to-air missile developed by France is mainly used to deal with low-altitude and ultra-low-altitude fighters and armed helicopters to defend the airport. It can also be used against cruise missiles. The missile is 2.94m long, with a diameter of 0. 156m, a weight of 84.5kg, a launcher length of 3.02m, a warhead focused on fragments, a total weight of 13.9kg and a killing radius of 6 ~ 8m m. The power plant is a single-stage solid rocket engine, and the guidance mode is full-range radio command guidance with a combat radius of 500 ~.
Colorful butterflies, such as butterflies with double moon stripes, monarch butterflies with brown veins, especially butterflies with fluorescent wings, have their hind wings that turn from golden to green and from purple to blue in the sun. Scientists have brought great benefits to military defense by studying the color of butterflies. During World War II, the Germans surrounded Leningrad in an attempt to destroy its military targets and other defense facilities with bombers. According to people's camouflage at that time, Vanovic, an entomologist in the Soviet Union, suggested that the color of butterflies was not easy to be found in flowers, and military facilities were covered with butterfly-like camouflage. Therefore, although the Germans went all out, the military base in Leningrad remained safe and undisturbed, laying a solid foundation for winning the final victory. According to the same principle, people later produced camouflage uniforms, which greatly reduced the casualties in the battle.
The beehive is 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-rhombic obtuse angle 109.28' and acute angle 70.32'. They are the most material-saving structures, and they are large in capacity and extremely strong, which makes many experts admire them. People imitate their structures and make honeycomb sandwich panels with various materials. It is not easy to conduct sound and heat, so it is an ideal material for building and manufacturing space shuttles, spaceships and artificial satellites. A polarizer sensitive to the direction of polarized light is arranged adjacent to each monocular of the compound eye of bees, which can be accurately located by using the sun. Based on this principle, scientists have successfully developed a polarized light navigator, which has been widely used in navigation.
Dragonflies can generate local unstable airflow different from the surrounding atmosphere through the vibration of their wings, and wells use the vortex generated by the airflow to lift themselves up. Dragonflies can soar under a small thrust, not only forward, but also backward and left and right. The forward flight speed can reach 72km/ h, and the flight behavior of dragonflies is simple, with only two pairs of wings flapping constantly. Scientists have successfully developed a helicopter based on this structure. When an airplane flies at high speed, it often causes violent vibration, and sometimes even breaks the wing, resulting in the plane crashing. Dragonflies are safe when flying at high speed, so people follow the example of dragonflies and add counterweights to the wings of aircraft to solve the thorny problem of vibration caused by high-speed flight.
Fleas have a high jumping ability, and aviation experts have done a lot of research on it. 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. According to the structural characteristics of insect's single compound eye, modern TV technology has made a large-screen color TV, and can also make a small color TV screen into a large picture, and can frame several specific small pictures at any position on the same screen. The same picture and different pictures can be displayed. According to the structural characteristics of insect compound eyes, scientists have successfully developed a multi-aperture optical system device, which is easier to find targets and has been applied in some important weapon systems abroad. According to the mutual inhibition principle of some aquatic insects compound eyes and monocular eyes, an electronic model of lateral inhibition is made and used in various photographic systems. The photos taken can enhance the image edge contrast and highlight the outline. It can also be used to improve the display sensitivity of radar, and can also be used for preprocessing of character and image recognition systems. Based on the processing information of insect compound eye and the principle of directional navigation, the United States developed an engineering model of terminal guidance seeker imitating insect compound eye search. Japan has developed new construction methods of construction machinery and buildings such as hexapod robots by using the morphology and characteristics of insects.
From Seepage Prevention of Yuanmingyuan Lake to "Man can conquer nature"
Recently, Yuanmingyuan spent a lot of money to "lay the bottom of the lake", which was clearly opposed by many environmental experts and environmentalists. The reason of Yuanmingyuan Management Office is to prevent water leakage and save water charges. The main objections of environmental experts are:
First, the anti-seepage project will block the last passage of 100 hectares of rainwater flowing underground, and the ecological environment of 100 hectares of wetland will be destroyed, losing the largest natural wetland in Haidian District, Beijing; Second, Yuanmingyuan Lake is an ecosystem. A large number of underwater microorganisms are silently responsible for inhaling carbon dioxide garbage and fish feces, recreating oxygen organic matter, and letting the clear fish swim happily in the lake. Now covering with plastic sheets will destroy the activities of microorganisms and the whole ecosystem will collapse. In the end, the whole lake turned into a stagnant water, the river stinked in an all-round way, and the dead fish on the river turned over, causing ecological catastrophe; Third, the practice of blocking stone crevices completely destroyed 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.
Speaking of environmental protection, we immediately think of the opposition between environmental protection and economic development, even if it is temporary. As for the anti-seepage project of Yuanmingyuan Lake, whoever believes that time is fair will have his own views in a few years. According to the latest report, the whole anti-seepage project at the bottom of the lake needs about 30 million yuan, and the annual water fee can be saved by more than10 million, which can be recovered in three years. A seemingly simple economic account. However, the ecological cost is not considered. The ecological cost may not have much to do with Yuanmingyuan itself, but it is related to the surrounding residents. It is related to the ecological environment of the whole region, the whole city, the whole country and even the whole earth. The Amazon rainforest is called the lungs of the earth. If the lungs can't work effectively and normally to maintain the ecological balance of the whole earth, it will have disastrous consequences.
There are so many things that human beings can do that it is not a problem to go to heaven and go to earth. Humans always have the inner impulse to conquer nature, and always think that "man can conquer nature", but most of them are punished by nature. Sanmenxia hydropower station is an extreme example; During the Cultural Revolution, artificial terraces were built all over the country, 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? Humans have 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. Perhaps one day, humans can control the direction of clouds in the sky and move them to places where it needs rain, which is much more convenient and cheaper than the "South-to-North Water Transfer Project" on the ground. If that day really happens, it will pose a greater threat to the survival of mankind.
In fact, man's greatest enemy is himself. In order to produce more eggs, produce more meat and satisfy human appetite, human beings "invented" lean pigs fed with "broilers", "duck stuffing" and "lean meat", and they ate more meat. The edible meat brought to human beings violates the laws of nature and is bound to be punished by them. This punishment may not appear for decades.
In the end, mankind can only be destroyed. Let's be kind to the natural environment and have more awe of nature, so as to achieve harmony and balance. Being kind to nature means being kind to yourself. Agree with 24| Comment on 2009-3-24 2 1: 19 snow season G | level 1.
The revelation of nature
In ancient times, lightning burned the forest. The ancients found that food after fire is more delicious than raw food, and fire can keep warm. When two stones collide, there will be sparks, so they learned to make a fire. The 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; ......

Squid and torpedo bait The capsule in squid can secrete black liquid, and when it is in danger, it will release this black liquid to trick the attacker into falling for it. Submarine designers imitate this function of squid, and readers design torpedo bait. Torpedo vinegar lure is like a pocket submarine, which can sail at the same speed according to the original course of the submarine, and can also simulate noise, spiral beat, sound signal and Doppler tone change. It is this vivid performance that makes it difficult to tell whether the enemy submarine or the attacked torpedo is true or not, and finally makes the submarine escape.
Shark skin swimsuit At the Sydney Olympic Games, a swimsuit changed the swimming mode of the world. Almost half of the gold medal winners are wearing a special swimsuit-one-piece shark suit. This shark suit imitates the skin structure of the overlord shark in the sea. Some rough dentate protrusions are designed on the swimsuit, which can effectively guide the water flow, tighten the body and avoid the vibration of the skin and muscles.
Since then, the bionic swimsuit has become more exquisite. The second generation of shark clothing has added some new highlights and a material called "elastic skin", which can reduce people's resistance in water by 4%. In addition, two accessories have been added, and the bumper made of titanium silicone attached to the forearm can make athletes swim more easily; Vibration control systems attached to the chest and shoulders can help guide the water flow.
Jellyfish-Jellyfish Ears Before the storm warning, the oldest coelenterate seemed to be able to predict the future and swam to the offshore early to avoid disaster. It turns out that jellyfish has an "ear facing the wind", and its "ear" (a small ball on a thin handle) has a small auditory stone covered with nerve receptors, which can hear infrasound (generated by the friction between air and waves, the frequency is 8 Hz-13 Hz, and the propagation speed is faster than storms and waves).
By simulating the organs of jellyfish that feel infrasound, scientists and technicians have designed a "jellyfish ear" instrument, which can forecast storms about 15 hours in advance. It consists of a loudspeaker, a vibrator for receiving infrasound waves, a transducer for converting this vibration into electric pulses and an indicator. This instrument is installed on the front deck of the ship, and the horn rotates 360. When it receives 8 Hz- 13 Hz infrasound, the rotation stops automatically, and the direction indicated by the horn is the coming direction of the storm. Indicators can also tell people the intensity of the storm. A man holds an egg and squeezes it hard, but no matter how hard he tries, it won't break. How can a thin eggshell be so strong? Scientists studied this problem with great interest, and finally found that the thin eggshell can bear such great pressure because it can evenly distribute the pressure to all parts of the eggshell. According to the characteristics of this "thin shell structure", architects have designed many buildings that are both light and material-saving. The roofs of the Great Hall of the People, Beijing Railway Station and many other famous buildings are of this "thin shell structure".

The story of Lu Ban inventing the saw.
The story of Lu Ban inventing the saw has been circulated among the people for thousands of years. Legend has it that one year, Luban accepted the task of building a huge palace. The palace needed a lot of wood, so Lu Ban sent his disciples up the mountain to cut down trees. Since there was no saw at that time, his disciples had to use axes to cut, but the efficiency was very low. The craftsmen had to work hard every morning. I'm exhausted. I can't cut down many trees, which is far from meeting the needs of the project. The progress of the project has been delayed again and again. Seeing that the project deadline is getting closer and closer, I am anxious for Luban. To this end, he decided to personally go up the mountain to see the situation of cutting trees. When going up the mountain, he accidentally caught a handful of weeds growing on the mountain, but suddenly cut his hand. Lu Ban wants to know why a grass is so sharp. So he picked a leaf and observed it carefully. He found many small teeth on both sides of the leaf. These little teeth are very sharp when he touches it gently. He knew that his hand had been cut by these small teeth. Later, Lu Ban saw a big locust eating leaves in a meadow. The two large molds are very sharp. As soon as they opened and closed, they quickly ate a big piece. This also aroused Lu Ban's curiosity. He caught a locust and carefully observed the structure of its teeth. He found that locusts also had many small teeth on their two big dies, which were used by locusts to bite grass leaves. These two things left a deep impression on Lu Ban, and also gave him great inspiration. He fell into deep thinking. He thought, if the tool for cutting wood is serrated, isn't it sharp? It will be much easier to cut down trees. So he made a bamboo with many small serrations from a big bamboo, and then went to a small tree to do experiments. The result is really good. After a few quick tugs, the bark was torn, and after a few more tugs, a deep ditch was made in the small tree stem. Luban is very happy. However, bamboo can not be used for a long time because of its softness and poor strength. After pulling for a while, some small serrations are broken and some are dull, so it is necessary to replace bamboo. This affects the speed of cutting down trees, and it is also a great waste to use too many bamboo pieces. It seems that bamboo is not suitable for making sawtooth, so we should find a material with higher strength and hardness to replace it. At this time, Lu Ban thought of the iron sheet. So they immediately went down the mountain, and the blacksmith helped to make small serrated iron pieces, and then went up the mountain to continue their practice. Lu Ban and his apprentice each pulled one end and pulled it up on a tree. I saw them coming and going, and soon I sawed off the tree, which was quick and labor-saving, and the saw was invented.
Before Luban, many people would encounter similar situations in which their hands were cut by weeds. Why only Luban was inspired by it and invented the saw is undoubtedly worthy of our consideration. Most people just think that this is a trivial matter in life and it is not worth making a fuss about. After the wound heals, they tend to forget it. However, Lu Ban has strong curiosity and correct ideas. He paid great attention to observing, thinking and delving into some small things in life, from which he found ways and ideas to solve problems and even obtained some creative inventions. This tells us a truth. Paying attention to many trivial things in life and thinking seriously will increase a lot of wisdom.

Fish have the ability to come and go freely in the water, so people imitate the shape of fish to build ships and use wooden paddles to imitate fins. According to legend, as early as the Dayu period, the working people in ancient China observed fish swimming and turning with their tails wagging in the water, so they put wooden paddles on the stern. Through repeated observation, imitation and practice, it was gradually changed to paddle rudder, which increased the power of the ship and mastered the means of capsizing. In this way, even in the rolling river, people can let ships sail freely.
The wings of flies (also called balance bars) are "natural navigators", and people imitate them to make "vibrating gyroscopes". At present, this instrument has been applied to rockets and high-speed aircraft, realizing automatic driving.
The fly eye is a kind of "compound eye", which consists of more than 30O0 small eyes. People imitate it and make a "fly-eye lens". The "compound eye lens" is composed of hundreds or thousands of small lenses arranged in sequence. It can be used as a lens to make a "compound eye camera" and can take thousands of identical photos at a time. This kind of camera has been used for printing plate making and copying a large number of tiny circuits of electronic computers, which greatly improves the work efficiency and quality. "Compound eye lens" is a new type of optical element, which has many uses.
Birds' wings have many special functions and structures, which make them not only good at flying, but also perform many "stunts" that are difficult for human technology to achieve at present. Hummingbird is a "helicopter" among birds. It can take off and land vertically and fly backwards. When sucking nectar, it does not stop on the flower like a bee, but hovers in the air. What a clever flight this is. It has become the dream of many aircraft designers to make vertical take-off and landing aircraft with hummingbird flight characteristics.
Inspired by penguins, people designed a new type of car "Penguin Polar Off-road Vehicle". This kind of car is stuck on the snow surface with wide bottom and pushed forward with a wheel spoon, which not only solves the polar transportation problem, but also can drive in muddy areas.
