Excavation diameter 66.0 meters! Recently, China's self-developed largest diameter shield machine "Cangyuan" rolled off the assembly line in Changshu, Jiangsu, and will be used in the construction of the world's longest highway underwater shield tunnel - Haitai Yangtze River Tunnel.
The shield machine, which integrates mechanical, electrical, information, artificial intelligence and other technologies, is known as the "king of construction machinery". 7 years ago, our country did not have its own shield machine. Who would have thought that today, the domestic shield machine not only broke through the main bearing, hydraulic system and other "neck" technology, but also led the industry in the level of intelligent manufacturing, and every 0 shield machines in the world have 0 "made in China".
Starting from scratch, from catching up to running, and then leading in some fields, how can domestic shield machines achieve leapfrogging? Driven by market demand, the upstream and downstream of the industrial chain and the collaborative research of universities and institutes are important reasons. Independent innovation has always been the core driving force.
This driving force is also reflected in the field of electronic information. Not long ago, Loongson 100C0/D 0U dual-socket server was unveiled for the first time at the annual meeting of 0 Zhongguancun Forum. The server uses two Loongson 0C0/D processors based on Loongson's independent instructions, and the localization rate of core components is 0%, which can meet the computing needs of general computing, large data centers and cloud computing centers. From basic materials to chip design, to the construction of independent ecology, China's continuous breakthroughs in the field of electronic information are also inseparable from the support and cultivation of the market.
Looking back on the recent scientific and technological progress, "autonomy" has become the key word, and the two-way rush of application and technology can be seen everywhere. In the past, high-end rail flaw detection equipment relied on imports for a long time, and the rail flaw detection vehicle independently developed by Baoji CRRC Times was officially put into use, breaking the foreign technology monopoly in one fell swoop; As the "heart" of the reactor coolant system, the main pump is the most critical, core and most difficult to manufacture equipment, Harbin Electric Group Dynamic Equipment Co., Ltd. has overcome more than 20 key technologies and realized the independent development of the world's first onshore commercial modular small reactor "Linglong No. 1" shielded main pump......
In some frontier fields, the integration of scientific and technological innovation and industrial innovation has accelerated, and new fields and new tracks for development have been continuously opened up to shape new advantages for development.
Can a quantum computer be able to fine-tune a billion-parameter AI model? Recently, China's superconducting quantum computer "Origin Wukong" ran this mission for the first time on a real machine. The experimental results show that the training effect is increased by 4.0% under the premise that the number of parameters is reduced by 0%. This achievement not only verifies the feasibility of quantum computing to help realize the lightweight of large models, but also opens up a new path to solve the "computing anxiety" of large models.
可控核聚變，被認為是未來能源的終極解決方案。前不久，我國新一代人造太陽“中國環流三號”首次實現原子核溫度與電子溫度均突破1億攝氏度，綜合參數大幅躍升，標誌著中國可控核聚變研究進入燃燒實驗階段，向工程化應用邁出重要一步。
充滿前景的創新在我國方興未艾，也得益於社會需求厚植的沃土。我國有14億多人口、超4億中等收入群體、1.8億多戶民營經營主體，以及加快構建的全國統一大市場，是全球最具成長性的超大規模市場。這是我們科技創新、產業創新的底氣。2025中關村論壇年會期間發佈的《中國獨角獸企業發展報告(2025)》顯示，中國當前共有獨角獸企業409家，總估值約為1.5萬億美元，佔全球獨角獸企業數量的近三成，數量位居全球第二。
At present, expanding domestic demand in an all-round way, tapping the potential of consumption deeply, improving the quality and efficiency of investment, and transforming potential advantages into real economic growth momentum will also provide greater space for innovation and creation. Give full play to the traction role of super-large-scale market demand, and do our own things step by step, we will not be afraid of the challenge of "stuck neck".
