The revelation of nature

Colorful butterflies, such as those with double moon patterns, those with brown veins, especially those with fluorescent wings, have golden wings, green wings and blue wings 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. Schwarzenegger, an entomologist in the Soviet Union, put forward the principle that the color of butterflies is not easy to be found in flowers, and covered military facilities with butterfly-like camouflage. Therefore, although the Germans went all out, the military base in Leningrad remained undisturbed, which laid 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.

Beehives are composed of small hexagonal beehives, and the bottom of each beehive is composed of three identical diamonds, which are exactly the same as those calculated by modern mathematicians-rhombic obtuse angle 109. 28', acute angle 70. 32' is exactly the same, it is the most material-saving structure, and it has a large capacity and is extremely strong, which makes many experts admire it. People imitate its structure and make honeycomb sandwich structural plates with various materials. This structural plate has high strength, light weight and is not easy to conduct sound and heat. They are ideal materials for making space shuttles, spaceships and artificial satellites. 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. 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, while Wells uses the vortex generated by the airflow to lift himself up. Dragonflies can soar under a small thrust, not only forward, but also backward and left and right, and its forward flight speed can reach 72 km/h. In addition, the flight behavior of dragonflies is simple, with only two pairs of wings flapping constantly. Scientists have successfully developed a helicopter based on this structural foundation. When an airplane flies at high speed, it often causes violent vibration, and sometimes even breaks its wings, causing the airplane to crash. Dragonflies rely on aggravated wing moles to fly safely at high speed, so people follow the example of dragonflies and add weights to the two wings of the plane 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 successfully manufactured a Harrier aircraft that can take off and land almost vertically. According to the structural characteristics of insects' single compound eyes, modern television technology has created a large-screen color TV, which can also be composed of small color TV screens. Some specific small pictures can be framed at any position on the same screen, and the same picture can be played as well as different pictures. According to the structural characteristics of insect compound eyes, scientists have successfully developed a multi-aperture optical system device that is easier to find targets, and it has been applied in some important weapon systems abroad. According to the mutual inhibition principle of some aquatic insects compound eyes, an electronic model of lateral inhibition is made, which can be used in various photographic systems. The photos taken can enhance the edge contrast of the image and highlight the outline of the image, and can also be used to improve the display sensitivity of radar, and can also be used for the preprocessing of text and picture recognition systems. Based on the processing information of insect compound eye and the principle of directional navigation, the United States has developed an engineering model of terminal guidance seeker with great practical value. Japan has developed new construction methods of construction machinery and buildings such as hexapod robots by using the morphology and characteristics of insects.

4。 The windward ear of jellyfish imitates the structure and function of jellyfish ear, and designs a storm predictor of jellyfish ear, which can predict the storm 15 hours in advance, which is of great significance to navigation and fishery safety.

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. This pathfinder is equipped with an ultrasonic transmitter, which blind people can use to find telephone poles, steps, people on bridges, etc. Nowadays, "ultrasonic glasses" with similar functions have also been made.

The invention of mankind-inspired by animals-ships and submarines came from people's imitation of fish and dolphins. Scientists have made the first batch of gas masks in the world according to the unique drug detection ability of wild boar nose. The rocket takes off by using the recoil principle of jellyfish and squid. Researchers have developed many military camouflage equipment for the army by studying the chameleon's color-changing ability. Scientists studied frog eyes and invented electronic frog eyes. The US Air Force has developed a miniature thermal sensor through the "hot eye" function of poisonous snakes. Humans also used the principle of leapfrog to design a toad ram (hang). Humans imitate the highly sensitive sense of smell of police dogs and create "electronic police dogs" for investigation.

Bionic and high-tech modern radar, a radio positioning and ranging device: scientists found that bat monsters rely not on eyes, but on an echo positioning system consisting of mouth, throat and ears. Because bat magic emits ultrasonic waves when flying, it can also detect the ultrasonic waves reflected by obstacles. Based on this, scientists have designed a modern radar-a radio positioning and ranging device ... Scientists have invented an artificial dolphin skin that can improve the speed of torpedoes by studying the tiny swimming resistance of dolphins; And a wheeled vehicle (jumping machine) that imitates kangaroo's movement in the desert.

Inspired by King Penguin, scientists from the Institute of Zoology of the former Soviet Academy of Sciences designed a new type of car-"King Penguin" brand polar off-road vehicle. The wide bottom of this car is directly attached to the snow surface and supported by a wheel spoon, and the driving speed can reach 50 km/h.

Scientists make space robots by imitating insects.

Inspired by bionics, British scientists are developing a new submarine, which can swim in an S shape by swinging its tail fin. The main innovation is the use of a device called "trunk actuator". "Elephant trunk" consists of a group of thin and soft hoses, which imitate muscle activity and promote fin movement. This new submarine can be used as an underwater mine-clearing submarine to deal with mines that will detonate at the slightest sound or interference.

The origin of compound eye camera

The compound eye of an insect is made up of thousands of small eyes. Because of the mutual inhibition between small eyes, eyes have the function of highlighting the image boundary and increasing the clarity. People made a "fly eye camera" for scientific research by imitating the honeycomb structure of small eyes in flies' stomachs. You can take 1329 photos at a time with a resolution of 4000 lines.

The revelation of nature is: the origin of fly-eye camera: the compound eyes of insects are composed of thousands of small eyes!
