A | (ECNS) -- China has successfully achieved the independent mass production of various high-end specialty steels, securing domestic supply chains across marine, aerospace, and electronics sectors. By manipulating atomic structures to prevent brittleness and corrosion, researchers have developed high-performance steel for offshore wind turbines that allows for thinner plates and reduced alloy usage. This breakthrough is part of a newly established research-to-production system covering deep-sea, shipbuilding, and aerospace fields. Key innovations include a 0.07mm-thick steel with high strength and ductility used in integrated circuit (IC) substrates and 5G receivers, and low-expansion steel for large aircraft molds. This year, seven new high-end steel types achieved major breakthroughs, with specialized steels mass-produced for electric vehicles, humanoid robots, and energy storage. To support this high-end transition, China’s steel industry has accelerated smart upgrades, boasting three global “Lighthouse Factories” and 38 benchmark intelligent manufacturing plants.

。 8月25日消息,微软已经确认Windows 11 26H2将于今年秋季推送,对于已经升级Windows 11 24H2或25H2的设备,升级到26H2只需下载一个174KB的启用包,不需要几个GB的完整升级包。
这一变化的基础是微软引入了共享维护平台,24H2、25H2和26H2三个版本建立在同一套底层代码上,安全补丁、错误修复和兼容性测试在多个版本间统一进行,三个版本之间的区别本质上只是哪些功能被激活。
不过下载量小并不代表26H2本身只有174KB,只是大部分组件已经通过之前的更新预装到系统中了,升级过程只是把这些功能激活,随后调整版本号。 而且174KB这个数字只适用于已经运行在24H2共享维护基础上的设备,仍在使用23H2的用户需要完整的功能更新,因为必须先切换到新的维护基础。 微软给出的对比数据显示,从23H2升级到25H2需要5.3GB的基础镜像加887MB累积更新包,总计约6.5GB,而174KB大约是6.5GB完整更新的三千分之一。
目前的Windows 11 24H2的家庭版和专业版将在2026年10月13日结束支持,26H2还将开启新的支持周期,预计会支持到2028年。
