为了解决在海上计算经线的问题,1675年英格兰国王查理二世下令建造了皇家格林尼治天文台,同时他还悬赏了一大笔奖金,给予第一个发明出在海上也能准确计时的钟表的人。
He offered an enormous cash prize to anyone who could build a clock that would remain accurate at sea.
该系统在设计时就已经设计成可自愈的,并且在各层级都可水平扩展,既能在大型数据中心里运行,也能运行在一台桌面电脑中,二者使用相同的代码库。
The system itself has been designed to be self healing and horizontally scalable at each level, applicable to run in a large datacenter, or even on a single laptop, all with the same code base.
在2.0版本倒计时的同时,我们不管是台前还是幕后都作了很多的工作,我想作为我的开篇博文最好的主题就是即将到来的2.0平台的预览了。
As we've had a lot going on both publicly and behind the scenes lately in the countdown to 2.0, I figured the best topic for my inaugural blog Posting would be a preview of the upcoming 2.0 platform.
何赛·穆里尼奥的整个赛前访谈可以在切尔西电视台收看到,今晚6:30,欢迎准时收看《比赛倒计时》节目。
José Mourinho's full preview of the game can be seen on Chelsea TV's Big Match Countdown at 6.30pm tonight.
因此,在厚承台设计时应考虑承台内部的完整应力流,而不是某一平截面上的应力分布。
Therefore, it is not stress distribution in certain even section but integrate stress flow inside the cap that should be considered.
因而,表不仅仅是一种计时器,而且是一台精密的仪表,素有“航空计算机”的美称。
Therefore, Carl F. Bucherer table is not only a timer, and a precision instrument, known as "aviation computer" reputation.
我们都知道时间是个复杂的概念。目前,世界上有一个由大约500台原子钟组成的网络,而我们就通过这些原子钟精确的滴答进行计时。
We all know time is a construct, and right now, it's kept by the very precise tick of an international network of around 500 atomic clocks.
振动台控制系统设计时对物理系统进行了两个基本假设:伺服阀线性、台面和负载刚性。
Currently, the design of shaking table control system is based on two assumptions, i. e. linear servo valve, and rigid table and payloads.
