油环注油器

Firstly, this thesis presented the theory of overspeed protection system. And pointed out the reason why the emergency stop system is often fails in stroke. And then use the theory of hydrodynamics and fluidics jet to solve the problem. The conclusions can be used to analyze the status of emergency stop system, which often acts early.

本文首先分析了该型超速保护的动作原理，指出该型危急保安器注油试验拒动的原因；首次利用流体力学的相关理论引入射流的概念，提出了改造方案，同时对该型危急保安器注油试验装置改造后飞环提前动作作出了理论分析。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
