The speed of China's scientific and technological development has left many countries jaw-dropping.
From artificial intelligence to high-speed rail, from shield machines to super steel, to quantum communication and Beidou systems, there are amazing breakthroughs in every field, almost all of which are stories of breaking the monopoly of technology and fighting their way out of the encirclement.
China's development in the field of artificial intelligence can be described as rapid progress.
This is inseparable from the strong support of the government, abundant data resources and a huge pool of scientific and technological talents.
Since the government made AI a national strategic priority and planned to become a global innovation hub in the field by 2030, China's AI technology has advanced rapidly.
China has made many major breakthroughs in deep learning, natural language processing, computer vision and other fields.
We've all heard of Baidu, Alibaba, and Tencent, right? They are not only showing their skills in e-commerce, search engines, social media and other fields, but also well-deserving world leaders in the research and development and application of AI technology.
Baidu's driverless technology, Alibaba's intelligent logistics system, and Tencent's AI medical care are all real hard-core technologies, and they are all at the top level in the world.
The name of the shield machine may be a little unfamiliar, but if you mention tunnelling and underground engineering, you must be familiar with it.
The shield machine is this kind of heavy machinery and equipment, which is known as "the sharp weapon of underground engineering".
In the past decade, China's shield machine technology has made leaps and bounds, breaking the technological monopoly of European and United States countries.
China's self-developed "Tianhe" shield machine is one of the most advanced equipment in the world, widely used in major projects such as subway and high-speed rail.
You know, in the past, we bought technology and equipment from others, and now we are not only self-sufficient, but also able to earn foreign exchange through exports, so that the international construction machinery market is impressed by China.
This progress has not only enhanced China's position in the international market, but also brought rich economic returns.
When it comes to China's transportation construction, how can it not improve the railway? China's high-speed rail development speed and scale are world-leading, from the initial introduction of technology to the current complete independent research and development, it only took more than a decade.
If there is a milestone, it is the "Fuxing" high-speed train, which not only has completely independent intellectual property rights, but also has a top speed of 350 kilometers per hour.
Today, China has the world's largest high-speed rail network, with a total length of more than 38,000 kilometers, which is the largest in the world.
Not only that, the safety and punctuality of the high-speed rail have also amazed many foreign friends.
It can be said that high-speed rail has become a beautiful business card of China.
You may have heard of Iron Man, but did you know about Super Steel? Super steel refers to alloy materials with ultra-high strength and good ductility, which are widely used in many fields.
China's self-developed super steel material not only has high strength and good toughness, but also has strong corrosion resistance, and can perform stably in extreme environments.
In major projects such as high-speed railways and bridges, super steel has been widely used, such as the Hong Kong-Zhuhai-Macao Bridge.
The 55-kilometre-long bridge connecting Hong Kong, Zhuhai and Macau is one of the longest sea-crossing bridges in the world.
To withstand the test of extreme weather such as seawater corrosion and typhoons, the construction of the Hong Kong-Zhuhai-Macao Bridge is inseparable from the support of super steel.
What is the Internet of Energy? In fact, it is very simple, it is to use Internet technology to realize the intelligent management of energy.
China's practice in the field of energy Internet has attracted global attention.
The government has promoted a number of policies and programmes to support the development of this emerging sector.
China has made a number of breakthroughs in smart grids, distributed energy resources, and energy storage technologies.
Smart grids can manage and distribute power resources more efficiently, and distributed energy resources make it possible for every household to become a producer and consumer of electricity.
Energy storage technology solves the problem of instability in the utilization of new energy.
The application of these technologies not only improves energy efficiency, but also greatly reduces carbon emissions.
When it comes to communication technology, everyone knows about 4G and 5G, but do you know quantum communication? Quantum communication uses the principles of quantum mechanics and has ultra-high security and anti-interference capabilities.
China is also at the forefront of the world in this field.
In 2016, China successfully launched the world's first quantum science experiment satellite "Micius", realizing the world's first 1,000-kilometer quantum experiment.
This is not only a major breakthrough in China's science and technology, but also a milestone in the field of quantum communication.
Subsequently, China also built the world's first quantum secure communication trunk line, realizing a wider range of secure communications.
Finally, let's talk about the Beidou system.
The Beidou Navigation Satellite System is a global satellite navigation system independently built and operated by China.
Compared with GPS, the Beidou system has the advantages of high-precision positioning, wide coverage, and signal stability, and is quite powerful.
The Beidou system has been widely used in transportation, fishery, disaster relief and other fields, not only to provide services for Chinese users, but also to provide navigation and positioning services for global users.
It can be said that the Beidou system is an important step for China's science and technology to go global, and it is also a powerful embodiment of enhancing the country's comprehensive strength.
The future of China's scientific and technological innovation is undoubtedly bright.
These achievements not only demonstrate China's technological strength, but also make great contributions to global scientific and technological progress.
As ordinary people, we should be proud of these achievements of the motherland, and pay more attention to and support China's scientific and technological development in our lives.
