According to this discovery, scientists quickly designed and manufactured the first batch of gas masks. However, this kind of gas mask does not use soil as adsorbent directly, but uses activated carbon with strong adsorption ability, and the shape of pig mouth can hold more activated carbon. Although the performance of adsorbent is getting better and better now, its basic style resembling pig's mouth has not changed.
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.
Fly eye invented the fly eye camera.
The sensitive perception of flies led to the invention of hazard detectors, which were used in dangerous workplaces.
The gliding skill of the eagle invented the glider.
The shape of the bird's thread has changed the appearance of the plane and is more aerodynamic.
The bones of birds have improved the skeleton structure of aircraft, making it lighter and stronger.
Acoustic detection of bats and dolphins invented ultrasonic radar.
What people get from bats is that airplanes fly by radar at night.
Cactus, ants, these natural things can be seen everywhere, so it is not unusual, but don't underestimate them.
Have you ever seen a group of small ants crawling on the wall? They always carry food as small as sand and walk in groups. That tiny figure's life is very weak. As long as it is pressed by people, its life may end like this. Although ants are small, they are very United. When an ant finds food, because the food is too big for him to carry, he immediately returns to his nest and informs his partner that everyone can unite and succeed. We are the same, if we can't unite, we are like a loose sand, with no strength at all; If we can cooperate, we can stand firm in life.
Cactus live in desert areas, where the heat is unbearable and there are many ferocious beasts. The situation is very dangerous. But the cactus lived there for a long time, but it didn't go extinct. This is because it grows sharp thorns to adapt to the dangerous environment, which makes animals helpless. This seems to tell us that we must rely on our own strong perseverance to overcome difficulties and solve the external difficult environment. As the saying goes, "Nothing is difficult in the world, only if you put your mind to it." This is a fact.
In nature, it inspires us too much. As long as we understand them with our heart, we can have a deeper understanding of life. Aren't cactus and ants good examples?
butterfly
Colorful butterflies, such as butterflies with double moon patterns, monarch butterflies with brown veins, especially butterflies with fluorescent wings, suddenly turn into gold, green and 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. 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, despite the German efforts, the military base in Leningrad remained intact, 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.
The constant change of satellite position in space will cause a sudden change of temperature, sometimes the temperature difference can be as high as two or three hundred degrees, which seriously affects the normal work of many instruments. Inspired by the fact that the scales on the butterfly will automatically change their angles with the direction of sunlight to adjust their body temperature, scientists have made the temperature control system of the satellite into a louver style, which has different radiation and heat dissipation capabilities. A temperature-sensitive metal wire is installed at the rotating position of each window, which can adjust the opening and closing of the window with the change of temperature, so as to keep the internal temperature of the satellite constant and solve a major problem in the aerospace industry.
beetle
When the beetle defends itself, it can spray a smelly high-temperature liquid "shell" to confuse, stimulate and scare the enemy. After dissection, scientists found that there are three chambers in the beetle body, which store dihydric phenol solution, hydrogen peroxide and biological enzyme respectively. Diphenol and hydrogen peroxide flow into the third chamber and mix with biological enzyme to have a chemical reaction, which instantly becomes venom at 100℃ and is quickly ejected. This principle has been applied to military technology at present. During World War II, the German Nazis made a new engine with huge power and safe and reliable performance according to this mechanism, which was installed on cruise missiles, making it fly faster, safer and more stable, and improving the hit rate. London, England suffered heavy losses when it was bombed. American military experts have developed advanced binary weapons inspired by the principle of beetle spraying. This weapon contains two or more chemicals that can produce toxins in two separate containers. After the projectile was launched, the diaphragm broke, and the two poison intermediates mixed and reacted within 8- 10 seconds of the projectile's flight, producing deadly venom at the moment when it reached the target and killed the enemy. They are easy to produce, store and transport, safe and not easy to fail. Fireflies can directly convert chemical energy into light energy, and the conversion efficiency reaches 100%, while the luminous efficiency of ordinary electric lamps is only 6%. The cold light source made by people imitating the luminous principle of fireflies can improve luminous efficiency by more than ten times and save energy greatly. In addition, an air-to-ground speedometer based on beetle apparent motion response mechanism has been successfully applied to aviation.
dragonfly
Dragonflies can generate local unstable airflow different from the surrounding atmosphere through the vibration of their wings, and use the vortex generated by the airflow to make themselves rise. 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 are safe when flying 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.
In order to study the aerodynamics and flight efficiency of gliding flight and collision, a mobile wing (wing) model with four-blade drive and remote horizontal control was developed, and the flight parameters were tested in the wind tunnel for the first time.
The second model tries to install a wing flying at a faster frequency, reaching the speed of 18 vibrations per second. What is different is that this model adopts a device that can variably adjust the phase difference between the front and rear wings.
The central and long-term goal of this research is to study the performance of aircraft driven by "wing" and compare it with the efficiency of aircraft driven by traditional propeller.
fly
The special feature of housefly is its fast flying technology, which makes it difficult to be caught by humans. Even behind it, it is difficult to get close to it. It imagines every situation, is very careful and can move quickly. So, how did it do it?
Entomologists found that the fly's hind wings 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 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 the object can be seen clearly in 360 degrees. 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.

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 under the slightest noise or interference.
