Spherical palace: a round nest skillfully woven by African warm birds with their beaks and feet. It starts with a circular bracket, forms a ball, and then hangs on a branch.

Stable light structure: The box nest built by Tian Feng is very delicate. Although it is a light structure, it has incredible stability.

Perfect gluing: the nest of weaving ants is made of leaves glued together. Their larvae can spit out adhesive and are ideal "glue bottles".

Round tower house on the tree: The house where birds live together looks like a crumbling pile of firewood on the tree, but its structure is very strong and can last for decades, often until the tree is crushed and broken.

The "stove" stove on the branch: Bird's nest is made of clay and is generally selected on a relatively stable branch. A bird's nest needs about 2500 grains of clay, all of which are taken away by the oven birds with their beaks. Platform complex: tropical stingless bees use beeswax to build beehives, which are stacked and combined, generally with 40 floors. It looks like a spaceship in the movie Star Wars and can accommodate 65,438+10,000 "residents".

Air-conditioned castle: termites can raise the temperature of their nests through an incredible pipeline system, cooling during the day and heating at night.

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. A very strange small gas analyzer was successfully copied from annoying flies. It has been installed in the cabin of spacecraft to detect the gas components in the cabin from fireflies to artificial luminescence;

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. 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.

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.

Lobster with keen sense of smell provides people with the idea of making odor detectors. . Gecko toes provide an encouraging prospect for manufacturing reusable adhesive tape.

The colloid formed by shellfish and protein is very strong, and this colloid can be used in everything from surgical suture to ship repair. In ancient times, people saw fish swimming freely in the water, so they invented boats and paddles based on fish's breasts and fins. When people saw birds flying in the sky, they invented airplanes and realized their wish of "flying to the blue sky". In the past, tanks had only one floor. If the enemy is on the right wing, it is necessary to airdrop the whole tank. People get inspiration from turtles. The tortoise can face in any direction on its back. Therefore, man invented the rotating gun. Seeing children playing remote control boat and friends playing automaton, I thought: remote control boat is propelled by propeller, and automaton is driven by spring, so the automatic boat should be driven by spring. I tried it at home, and it succeeded, but I couldn't sail fast. I thought the dolphin's tail was triangular and it swam very fast. I made the stick at the tail into a triangle, and it succeeded. Nature has given us so much inspiration! Humans have found something from dragonflies and whales, but flies have inventions that everyone hates! Entomologists found that the back wings of flies degenerated into a pair of balance bars. When it flies, the balance bar vibrates mechanically at a certain frequency, which can adjust the movement direction of its wings. It is a navigator to keep the balance of flies. Based on this principle, scientists have developed a new generation of navigator-vibrating gyroscope, which greatly improves the flight performance LlJ of the aircraft, enables the aircraft to automatically stop the dangerous rollover flight, and automatically restore the balance when the body is strongly inclined, even when the aircraft is in the most complicated sharp turn. The fly's compound eye contains 4000 single eyes that can be imaged independently, and almost 360 can be seen clearly. Objects within range. Inspired by the fly's eye, people made a fly's eye camera consisting of 1329 small lenses, which can take 1329 high-resolution photos at one time. It is widely used in military, medical, aviation and aerospace fields. Flies have a particularly sensitive sense of smell and can quickly analyze dozens of smells and respond immediately. According to the structure of flies' olfactory organs, scientists have converted various chemical reactions into electric pulses, and made a very sensitive small gas analyzer, which is widely used in spacecraft, submarines, mines and other gas components, making the safety factor of scientific research and production more accurate and reliable. Nature is really a good teacher for human beings!

Answer supplement

At present, the development of our human means of transportation is partly due to those diligent and knowledgeable scientists, and the other half is due to our human learning from nature. Humans invented radar according to bats and electronic frog eyes according to frogs, which made great contributions to world traffic and military affairs. Do you know how the helicopter was invented? It turns out that dragonfly can be said to be the flying champion among insects. Inspired by it, people began to fantasize about building a plane that rose directly from the ground without a runway. The Wright brothers were the first people to make a helicopter model. 1907, the world's first dragonfly-like helicopter was successfully developed by French technicians Borregg and Richter. This helicopter has no wings and two long arms on both sides of the fuselage. Each arm has two four-blade propellers, which can rotate horizontally. When the four propellers rotate, the helicopter can rise vertically from the ground. During the flight test, it was found that the aircraft was seriously vibrated and its safety performance was poor, and many accidents occurred. Scientists have repeatedly studied the flying appearance and wing structure of dragonflies, and found that there is a thick brown piece on the side of dragonflies' wings, which can keep the flight smooth. After scientists discovered it, they immediately added weight to the wing side of the helicopter, which greatly improved the stability of the aircraft and rarely caused accidents, so the helicopter was born. Scientists have found inspiration from animals, made inventions and created things. Biology is really a good teacher for human beings.

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, adding 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 horn, a resonator 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. Architects are based on this "thin shell knot"
