中国“新四大发明”之首-欣闻世外
导读
中国的“新四大发明”,蛇缠腰分别是高铁、支付宝、共享单车和网购吊唁的意思 。近日中国在北京和上海之间运营的高铁以350公里/小时的速度,创下世界最快长途高速列车的纪录。这既是行业政策也是工程技术的胜利欧兴田。(英国《经济学人》)

中国标准动车组
The China Standardized EMUis an electric multiple unit high-speed train developed by China Railway Corporation.

It designates Fuxing Hao(Rejuvenation)间客全文阅读, nicknamed "Blue Dolphin" (CR400AF) and "Golden Phoenix" (CR400BF).

“复兴号” 是拥有完全自主知识产权的的中国标准动车组(China Standardized EMU),试验速度可达400km/h及以上,持续运行速度为350km/h。

9月21日,拥有完全自主知识产权的的中国标准动车组“复兴号”与乘客见面,高铁时速重回350成为现实。至此,中国再次成为世界上高铁商业运营速度最快的国家。

为何研发复兴号?
小闻
统一的技术标准体系
‘复兴号’中国标准动车组构建了体系完整、结构合理、先进科学的高速动车组技术标准体系,标志着我国高速动车组技术全面实现自主化、标准化和系列化,极大增强了我国高铁的国际话语权和核心竞争力。(人民日报)

我们当初从海外引进了1型车、2型车、3型车和5型车四种不同的技术平台。基于不同技术平台研发出的车型“和谐号”不仅司机操作台不同夏洛特麦金尼,车厢定员座位数与布局不同,有些车甚至车厢连挂处的高度都不一样。如果某节车出现故障,需要组织乘客换乘24睡姿图,临时调来的车一旦车型不同,就会出现要么“挂不上”,要么“缺座位”。

标准不一,不仅增加了运营难度,也提高了运营和维保成本梦见海市蜃楼 。因为车型标准不统一,蒋多多高铁车站不得不将每种车型都预留备用车来应急虫虫果实 ,动车检修的车间也要把4种车的零部件全配备约拿的家 ,甚至高铁司机也要把各种车型都学习一遍。

因此,我国急需针对不同型号的动车组建立统一的技术标准体系,实现动车组在服务功能、运用维护上的统一柳条人,提高效率,降低成本。

复兴号有哪些不同李林金?

四大特色
“复兴号”与“和谐号”有什么不一样最牛班规?
“寿命”更长(“复兴号”设计寿命比“和谐号”多10年)
“身材”更好(动车组车顶没有“鼓包”---受电弓和空调系统下沉到车顶下的风道系统中)
“容量”更大(高度4米,比“和谐号”高30厘米王春露,座位间距更宽)
“舒适度”更高(车厢内实现了WiFi网络全覆盖)

This was a _____ of industrial policy asmuch as of engineering. China's first high-speed trains started _____ only a decade ago; today the country has ________ of high-speed track, more than the rest of the world combined.
2.China could not have built this without a strong _______. The state provided funds for research, land for tracks, ______ for loss-making railways镜仙缘 , subsidies for equipment-makers and, most controversially, ________ for foreign companies to share commercial secrets.
3.High-speed rail is a _____ example of the Chinese government's prowess at identifying priority industries and ______ money and policy tools to nurture them. It inspires awe ofwhat it can accomplish and fear that other countries stand little chance against such a formidable (难以对付的)________.
4.Yet there have also been big industrial-policy ______, notably the failure to develop strong _____ anufacturers and semiconductor-makers.
