2, do the human teacher of the animals are tree branch wireless charge : flies, fish, electric fish, jellyfish, bats, frogs, sawgrass and so on. Human beings have modeled the "vibrating gyroscope" (used in rockets and high-speed aircraft) on the "row wings" of flies (also called balance rods).Realized autonomous driving). The eye of a fly is a "compound eye", which is composed of more than 30O0 small eyes, and people imitate it to make a "fly eye lens".
3. Many animals are human teachers. For example, bats, whose ultrasonic positioning method has allowed scientists to develop ultrasonic positioning systems that can locate submarines underwater. Spiders, for example, whose filaments have allowed scientists to develop nanomaterials that are both clean and tough.
4. Radar was invented by studying bats. Bats emit an ultrasonic wave that bounces off objects and is inaudible to humans.Radar was invented based on this characteristic of bats. Radar is used in all kinds of places, such as: aircraft, aviation, etc. By studying the swim bladder, the submarine was invented. Inside a fish's stomach is a substance called the swim bladder, which is filled with air. Bat and radar In the past, people did not have radar when they fought, and they were always attacked by planes when they were not ready. Scientists have studied bats for a long time and found that bats have poor eyesight but can accurately catch prey at night. Why? It turns out that each bat can emit an "ultrasonic wave" in its mouth, which will reflect back at objects.
1, the story of two iron balls landing at the same timeIn the process of pursuing truth in his youth, Italian scientist Galileo dared to challenge authority and doubted the so-called truth of Aristotle, the philosopher believed in by everyone. After repeated tests and verification, Galileo walked on the Leaning Tower of Pisa in people's mockery and suspicion and confirmed the truth with experiments.
2, 【 Boyle 】 Boyle childhood was not particularly smart, speak a little stutter, not like lively games, but is very studious, like to read quietly thinking. He received a good education from an early age, and from 1639 to 1644, he toured Europe. During this time, he read a lot of science booksHe wrangled his eyes and was busy licking the back leg that stuck out like a pistol. He felt neither dull nor happy, and had nothing to hurry about.
2. Little dog Spot is very funny and cute. It is particularly strange when eating, eat a bite to look around, and then eat a bite or look around, as if someone will rob him. He runs very fast, too. Sometimes I can't outrun him. Little bit sleep always used to put the ear to the ground, as long as there is a little movement, it will wake up immediately.
3, describe the animal good words good sentences good paragraph peacock that small head like a few jade flowers,The unfold color screen is like a huge feather fan, a black ring, black, green, yellow, like countless big eyes. The pigeon had feathers as white as snow, a small reddish-brown beak, clever eyes, slender legs, and feet that looked like chicken feet but had no fins. Its ears pointed, nose black, round eyes like a pair of big glass balls, the beard on both sides of the mouth a shake a shake, the whole body hairy, a yellow a white. Sometimes he clumps himself up like a pompom. A group of birds chirping past from our heads, a large honey peak is falling on a golden winter jasmine, beautifulThe butterflies are flying among the flowers. Spring has arrived, and they are busy living up to the opportunity.
1, examples of bionics Dragonfly and aircraft flight technology Dragonfly is a kind of insect in nature, with excellent flight technology and superb air hover ability. By studying the flight mechanism of dragonflies, scientists have discovered the mystery of their wing structure, which can be applied in aircraft design. The wing design of the aircraft refers to the structure of the dragonfly wing, which improves the flight efficiency and stability of the aircraft.
2, bats and radar: at night, or artificially shield the eyes of bats, bats can still fly freely and avoid obstacles. Scientists invented radar based on the way bats find their way by echolocation. The role of radar is very wide, we often sit on the plane, it can not be separated from the help of radar, radar through the antenna radio waves, radio waves encountered obstacles are reflected back, displayed on the electronic instrument. 3, Squid and sidewall hovercraft Squid are amazing sea animals, known as sea rockets. It can reach a top speed of 150 kilometers per hour, which mainly depends on its simple structure and safetyReliable high-speed water jet thrusters. It is modelled on a side-wall hovercraft with a jet propeller, capable of up to 40 metres per second and capable of accelerating in shallow water less than a metre deep. People build boats in the shape of fish, and use OARS to imitate fins. 4, bionics scientist Locke invented the electronic frog eye according to the frog eye principle, this device can help the radar system distinguish between true and false targets, improve anti-interference ability, and quickly and accurately identify aircraft, ships and missiles. Based on the jellyfish's ability to sense infrasound, scientists have developed a "jellyfish ear" device that can predict storms and indicate their intensity, providing guidance to ships15 hours or so of warning.
5, by the revelation of the fly invented the vibrating gyroscope Fly's row wing (also called the balance rod) is a "natural navigator", people imitate it made a "vibrating gyroscope". Such instruments have been used in rockets and high-speed aircraft to achieve automatic piloting. (3) The electric fish inspired the invention of the Volt battery Electric fish has a strange power generating organ in the body. These electricity-generating organs are made of many translucent disk-shaped cells called electroplates or discs.
6. Examples of bionics are as follows: Fireflies and artificial cold light: In nature, the light emitted by fireflies isIt does not produce heat, so it is also called "cold light". The cold light emitted by fireflies not only has a high luminous efficiency, but also the cold light emitted is generally very soft, very suitable for human eyes, and the intensity of light is relatively high. Therefore, biological light is an ideal light for human beings.
Cage squirrels tree branch wireless charging exercise is relatively large tree branch wireless charging , so the bigger the squirrel cage is, the better. Because squirrels like itJump down, so the cage needs a certain height. When keeping squirrels, you can prepare a well-ventilated wire, or half glue and half iron cage.
Squirrels are very lively, especially like to climb trees, the activity space is more three-dimensional, should try to choose a wide and high cage. Since squirrels habitually nest in trees, the nest box should be installed high in the cage. The nest box can be used by birds and the entrance and exit of the nest box at a high place instead. Squirrels can move very quickly, so be careful when opening and closing doors to avoid escaping in a gap. In case of escape, if you suddenly grab hard, to avoid being bitten by the squirrel.
Squirrels are very lively,When choosing a cage, try to let the squirrel have enough room to move around, choose a wide and tall cage. Squirrels are used to nesting in trees, so the nest box should be installed high up in the cage. Squirrels move very quickly, pay attention when opening and closing doors, and escape every minute. A squirrel is not as human as a dog, and even if you keep it for a year, it may not recognize you as its owner.
Squirrels can be kept in the feeding cage, usually feed nuts, the most important thing is to reasonably feed water, water drink more tree branch wireless filled , squirrels are easy to get sick. Squirrels are members of the Sciuridae family of the rodent order. looseThe living habits of rats are different from those of other animals, and they enjoy activities in broad daylight. Squirrels are typically small tree-dwelling animals with long, slender bodies.
Feeding method: Food: squirrels feed on the seeds of fagaceae plants, and can feed nuts such as walnuts and chestnuts. Cages: Because squirrels are very lively, especially like to climb trees, and the activity space is more three-dimensional, you should try to choose a wide and high cage and install the nest box at the height of the cage. Baby squirrel feeding: Warm milk is initially fed through a straw 3-5 times a day.Double cages should be prepared, because squirrels like to do ladder exercise. There should be a cabin in the cage for himRest and hide food, need to buy a hamster kettle, water with the sink is easy to pollute, the bottom of the cage mat newspaper or wood chips, replace once a week tree branch wireless charging ; The daily feeding amount per squirrel is about 30 grams of mixed feed, 200 to 250 grams of roughage and 150 to 200 grams of green juicy feed. Feed three times a day in the morning, middle and evening.
