Feelings about the rapid development of science and technology in the 20th century:
1. Nowadays, smart phones are rising in China, and the mobile phone industry is also developing rapidly. China used to be the largest assembly base for mobile phone companies, and China provided them with labor and markets. But now China is not what it used to be, from Xiaomi to Huawei, these domestic mobile phones.
It is gradually entering the international stage.
From the production of a memory card to the manufacturing technology of mobile phones with complete intellectual property rights, Chinese companies have put too much effort into it. Originally, each mobile phone uses the patented technology owned by foreign electronics manufacturers, and the cost of each mobile phone is several times that of the current one, and the enterprise surplus is small, and it is impossible to pour too much money into the development of new technology, and China's development is subject to others everywhere.
2. In fact, it is made from China.
Creating in China reflects not only China's achievements in science and technology, but also the inexpensive goods with the connotation of China's science and technology culture in the world, we have no reason to deny that China's science and technology is Chinese culture.
Injected with fresh connotations.
3. China's business card - high-speed rail. High-speed rail is the passage that brings China to the world, and Chinese culture will also be carried by it to every corner of the world. As a new mode of transportation, high-speed rail is faster than trains, more convenient than airplanes, and more importantly, China has complete independent intellectual property rights.
China High-Speed Rail. Going abroad is an innovation in modern transportation.
With a speed comparable to that of an airplane, and a pleasure comparable to that of a yacht, it is impacting the modern mode of transportation again and again under the premise of safety. In the end, the high-speed rail went abroad, highlighting China's scientific and technological development in a foreign country and conveying the message of China's going global.
4. The five major railways connect China with the world. From the ancient Silk Road.
From Europe to Africa, the railway lines connecting the southeast, northwest and northwest are the most beautiful scenery left by China on the world map. Since then, Chinese characters, Chinese calligraphy.
Chinese poetry will converge on the sea of world culture through the railway.
5. The Chinese Dream.
It's not a grand vision to look up to, it's a big dream made up of small dreams in various fields. When the dream of science and technology promotes the formation of the cultural dream, Chinese culture will no longer be just the traditional "Book of Songs".
Zhouyi, it will be integrated into the atmosphere of the times brought by technology.
Chinese culture has ushered in a new chapter that keeps pace with the times. Science and technology are Chinese culture.
Infused with connotation, it is like a sea formed by the convergence of beautiful drops of water, which must be dazzling.

Answer: Human life is better, the economy is more developed, and there is gradually a **. In this way, the future life of mankind is no longer seriously threatened.
Processing uses sound energy and can be applied to ultrasonic welding, ultrasonic cleaning, ultrasonic machining, ultrasonic probing, "stirring", etc. This is mainly applied in the form of mechanical energy of sound energy, such as the application of the "cavitation" effect. Ultrasonic waves propagate forward in the cleaning solution in a dense phase, stretching and squeezing the liquid, causing tens of thousands of tiny bubbles to be generated in the liquid. >>>More
