Inspiration from nature?

After reading the book Animal World, I learned about the life characteristics and special abilities of woodpeckers and anteaters. From them, I suddenly thought of a problem and got an inspiration:

In rural orchards, we often find pests getting into tree trunks and ripe fruits. In order to protect the fruit trees, farmers have to spray a lot of pesticides. What is the result? Not only is the cost high, but people eat it, and the pesticides that exceed the standard are scary. If pests are not killed in time, people have to cut down those "incurable" fruit trees. In modern rural areas, it is impossible for so many woodpeckers to help fruit trees see a doctor.

Nature has given people a lot of inspiration. Planes were invented according to dragonflies, and streamlined boats were invented after whales at the bottom of the sea. So I'm thinking: why don't we make a portable pest control machine by imitating the mouth of woodpecker and the tongue of anteater? In this pest control machine, we can install a computer chip, so that it can accurately detect diseased trees. Then, we can press a red button on the handle, and a pointed hooked steel pipe similar to a woodpecker's mouth will pop out from it. It can accurately make a tiny hole in a tree with pests, and then hook it out with a hooked steel pipe mouth. What about termites? Don't panic, we can put the steel pipe mouth in first, then press the green button, and an anteater-like tongue will pop out of it. As soon as the sticky long tongue "drills" into the hole, termites are easily and completely eliminated.

From the foraging of woodpeckers and anteaters, we got an inspiration and an innovation.

The revelation of nature

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 new computing mode computer.

There are still many inspirations that human beings get from nature. For example, an arch bridge was built to imitate the characteristics of egg shape; Inspired by the flight of birds, people invented airplanes. I cut off my fingers from the thatch and invented the saw ... Many animals and plants in nature, with their own unique lifestyles, hint at the mysteries of nature.

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.

The rattlesnake missile, like the rattlesnake, can accurately track the enemy with its "hot eyes" until it is destroyed. Because the "hot eyes" of the rattlesnake can judge the position of the enemy according to the temperature of the enemy, the rattlesnake missile can accurately hit planes, warships, tanks and the like. A maneuvering low-altitude short-range all-weather ground-to-air missile developed by France. It is mainly used to deal with low-altitude and ultra-low-altitude fighters and armed helicopters to defend airports and ports, and can also be used to deal with cruise missiles. The missile is 2.94 meters long, with a diameter of 0. 156 meters, a weight of 84.5 kilograms and a launcher length of 3.02 meters. The warhead focuses on fragments, with a total weight of 13.9 kg and a killing radius of 6 ~ 8 meters. The power plant is a single-stage solid rocket engine, and the guidance mode is full-range radio command guidance, with an operational radius of 500-8500m and an operational altitude of 50-3000m. The missile has semi-off-road maneuverability.

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.

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:

1. The anti-seepage project will block the last passage of 100 hectares of rainwater to the underground, and the ecological environment of 100 hectares of wetland will be destroyed, losing the largest natural wetland in Haidian District, Beijing; Secondly, Yuanmingyuan Lake is an ecosystem, and a large number of underwater microorganisms silently undertake the responsibility of inhaling carbon dioxide garbage and fish manure, 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.

When it comes to environmental protection, we immediately think of the opposition between environmental protection and economic development, even if it is temporary. Specific to the "Yuanmingyuan Lake Leakage Prevention" project, 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, which can save water fee10 million yuan every year, and the cost can be recovered in three years. The seemingly simple economic account does not consider the ecological cost. The ecological cost may not have much to do with Yuanmingyuan itself, but it is related to the surrounding residents, to the ecological environment of the whole region, and to the ecological environment of 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 be disastrous.

There are "too many things" that human beings can do, and 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 built around water, and forests were destroyed to grow grain. There are countless examples of this violation of the laws of nature. What is the final result? Causing 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 human survival.

With the progress and development of human science and technology, there are more and more ways for human beings to influence nature. Less precipitation? Artificial precipitation enhancement. Maybe 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 Diversion Project" on the ground. If there is such a day, it will pose a greater threat to the survival of mankind.

Man's greatest enemy is actually himself. In order to produce more eggs, produce more meat and satisfy human appetite, human beings "invented" lean pigs fed with "broilers", "stuffed ducks" and "lean meat". What does eating meat bring to human beings? Violating the laws of nature will inevitably be punished by them. This kind of punishment may take decades or hundreds of years to appear.

In the end, it can only be human beings themselves. It is better to be kind to the natural environment and have more reverence for nature, so as to achieve harmony and balance. Being kind to nature means being kind to yourself. Respondents: wwcctqqqwJFDHA | Level 1 | 2011-3-2711:51.

The Invention of Human Beings —— Enlightenment from Animals

1. Ships and submarines come from people's imitation of fish and dolphins.

2. Scientists 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.

4. Humans imitate the highly sensitive sense of smell of police dogs and make "electronic police dogs" for investigation.

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. The color of colorful butterflies is abrupt, such as the butterfly with double moon pattern and the monarch butterfly with brown veins. Especially butterflies with fluorescent wings, and then 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.

7.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.

Bionics and high technology

1. Scientists invented the artificial dolphin skin which can improve the torpedo speed by studying the tiny swimming resistance of dolphins; And a wheeled vehicle (jumping machine) that imitates kangaroo's movement in the desert.

2. Inspired by the Emperor Penguin, scientists from the Institute of Zoology of the former Soviet Academy of Sciences designed a new type of car-"Emperor 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.

A research team of Australian National University has developed a small navigation and flight control device by studying several insects. This device can be used to equip a small aircraft for Mars exploration.

Inspired by bionics, British scientists are developing an S-shaped "swimming" that can swing through the tail fin.
