不精密

We made sophisticated tools, equipment, and the rest of the world may have not known about us; although we were truly a great and powerful nation.

我们作了精密的工具，设备，而其余的世界可能已经不知道我们；虽然我们是一个真正强大的民族。

In the Expo of 1888, Gaudi was charged by the Marquis of Comillas the design of the Pavilion of the Transatlantic Company in the Maritime section. That same year, Gaudi was flooded with a wide variety of projects. Of these the Episcopal Palace of Astorga was the only one censored by the Royal Academy of the Bellas Artes of San Fernando. Because it was a public work charged by the then Ministry of Justice and Grace, that his plans were so minutely refined that the project began in 1893, two years after it had been proposed. By this time, the Bishop had passed away and Gaudi had antagonized the clergy, leaving the project.

在1888年的万国博览会，高第受Comillas侯爵之邀，负责设计大西洋彼岸的海运部门的摊位棚帐，之后在同一年，高第受到大量的计画邀约，而其中一件Astorga主教广场的计画被San Fernando艺术皇家学院审核不过关，因为这是一件由教会的正义、恩典部门教士们所授与的公共建筑计画，所以计画不断地、精密地被审核，直到1893年---计画提出的第二年才开始动工，此时主教已过世，高第也因此对这些神职人员不满而放弃了这个计画。

对高压背压式气动测量用于小量程线性尺寸测量的静态特性曲线的理论工作拐点进行了推导，对气动测量系统中的喷嘴-挡板型气动传感器中的关键部件——主喷嘴和测量喷嘴的参数进行了理论设计，对主喷嘴和测量喷嘴的不同组合，将影响测量系统静、动态特性指标的喷嘴参数进行了对比实验和优化设计，并通过实验验证了理论推导，从而使气动测量系统量程的示值范围达到40μm，灵敏度达到100mv／μm，分辨率达到0.05μm，测量不确定度小于0.2μm，满足了压缩机缸盖软体垫片厚度尺寸精密测量分组的要求。

I'm extremly fortunate,for i'm not a rocksy who on need to calculate critically how many years does ocean wave turn a rock to the figure of the goodess,but i canmagined that how does the God caver uniquely by his invisible hands at night

我何其幸运，因为我也不是地质学家，用不着去精密地推算海浪需要多少年将一块岩石变成神女的模样，而我会超越时空地想象，黑夜里上帝是怎样用无形的手在别具匠心地雕琢。
