1, submarine:
Submarine is a kind of ship that can run underwater, and its design is inspired by the shape and swimming style of fish. The streamlined body and scaly surface of fish can reduce the resistance of water flow and make fish swim quickly in the water.
The submarine also adopts a similar design. By changing its own weight and buoyancy, it can float and dive. At the same time, the propeller propulsion system of submarine and the tail fin propulsion principle of fish are also very similar.
2, waterproof material:
Fish scales are waterproof and can keep fish dry. According to the scale structure of fish, many waterproof materials have been developed. These materials have scale-like structures on their surfaces, which can effectively prevent water infiltration and are widely used in the fields of architecture, electronics, aerospace and so on.
3, artificial gills:
Fish gills can extract oxygen from water for fish to breathe. According to the principle of fish gill, people designed an artificial gill. This artificial gill can simulate the breathing process of fish and extract oxygen from water for human breathing. This technology has broad application prospects in diving and rescue fields.
The contribution of scientific inventions to people's lives;
1, improve the quality of life:
Scientific inventions can provide people with better living conditions and facilities, thus improving their quality of life. For example, the invention of air conditioner can make people enjoy cool air in hot summer, the invention of washing machine can save people the hard work of manual laundry, and the invention of automobile can make people travel more conveniently and quickly.
2. Promote social progress:
Scientific inventions can also promote social progress and development. For example, the invention of the Internet has made the dissemination of information faster and more convenient, thus promoting the development and progress of society. At the same time, the invention of new materials and technologies can also promote the development of industry, medical care, energy and other fields, thus promoting social prosperity and progress.
3. Improving human health:
Scientific inventions can also improve human health. For example, the invention of new drugs and medical technology can treat various diseases and prolong people's life. At the same time, the invention of new fitness equipment and exercise methods can also help people keep healthy and improve their quality of life.
