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.

17. The capsules in squid and torpedo bait can secrete black liquid. 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.
18. Spider and armored biologists have found that the strength of spider silk is five times that of steel wire with the same volume. Inspired by this, a technology company in Cambridge, England, tried to make high-strength fibers similar to spider silk. Composite materials made of this fiber can be used as structural materials such as bulletproof vests, bulletproof vehicles, tanks and armored vehicles.
19. Giraffes and "anti-Dutch clothing" giraffes are the tallest animals in the world at present. The distance between their brains and hearts is about 3 meters, and blood is sent to their brains by blood pressure as high as 160~260 mm Hg. According to general analysis, when giraffes bow their heads to drink water, their brains are lower than their hearts, and a large amount of blood will flood into their brains, which will increase their blood pressure even more, so giraffes will die of diseases such as cerebral congestion or blood vessel rupture when drinking water. But the giraffe's thick skin tightly binds blood vessels, which limits blood pressure. Aircraft designers and aviation biologists have designed a novel "anti-load suit" based on the principle of giraffe skin, thus solving the pain caused by cerebral ischemia when ultra-high-speed fighter pilots suddenly accelerate their climb. There is a device in this "anti-load suit", which can compress air when the plane accelerates, and it can also exert corresponding pressure on blood vessels, which is better than the thick skin of giraffe.
20. "Whale Back Effect" between whales and submarines Contemporary nuclear submarines can dive under the ice for a long time, but if they launch missiles under the ice, they must break the ice and float up. This is a mechanical problem. Diving experts are inspired by the fact that whales break ice and breathe every 10 minute. In terms of the podium coaming and superstructure protruding from the top of the submarine, they strengthened the material strength, simulated the whale back, and truly achieved the "whale back effect" when breaking the ice.
2 1. butterflies and satellites with temperature control system travel in space. When they are strongly radiated by sunlight, the satellite temperature will be as high as 200 degrees Celsius; In the shadow area, the temperature of the satellite will drop to about-200 degrees Celsius, and it is easy to bake or freeze the precision instruments on the satellite, which once made the space scientists break their brains. Later, people were inspired by butterflies. It turns out that the butterfly has a layer of tiny scales on its body surface, which can regulate its body temperature. Whenever the temperature rises and the sun shines directly, the scales automatically open, reducing the radiation angle of the sun, thus reducing the absorption of solar heat energy; When the outside temperature drops, the scales automatically close to the body surface, allowing the sun to shine directly on the scales, thus controlling the body temperature within the normal range. After research, scientists designed a temperature control system similar to butterfly scales for artificial earth satellites.

Lu Ban, a famous craftsman in ancient China, cut his hand while cutting trees up the mountain. He wants to know how a grass can be so powerful. After careful observation, he found that there were many sharp teeth on the leaf edge of silk grass. So Lu Ban invented the woodworking saw.
Flies have no noses. What does it rely on to act as a sense of smell? It turns out that the "nose" of flies-olfactory receptors are distributed on a pair of antennae on the head. A very strange small gas analyzer was successfully copied. This instrument has been installed in the cockpit of the spacecraft to detect the composition of the gas in the cabin. It can also measure harmful gases in submarines and mines. This principle can also be used to improve the input device of computer and the structural principle of gas chromatography analyzer.
As early as 1940s, people created fluorescent lamps based on the study of fireflies. In recent years, scientists first isolated pure fluorescein from fireflies, then isolated luciferase, and then synthesized fluorescein artificially by chemical methods. Biological light source composed of fluorescein, luciferase, ATP (adenosine triphosphate) and water can be used as a flash lamp in mines filled with explosive gas. Because this lamp has no power supply and does not produce magnetic field, it can be used to clear magnetic mines under the irradiation of biological light source.
