This model can estimate the size of the affected area in the event of a full-bore rupture by the diameter, the operating pressure and the length of pipeline Hazard area is directly proportional to the operating pressure raised to a half power, and to the pipeline diameter raised to five-fourths power, but inversely proportional to the pipeline length raised to a quarter power.

应用该模型可以通过管道直径、工作压力和管道长度计算出全口径断裂事故的影响范围。危险影响区域与工作压力的平方根成正比，与管道直径的5/4次幂成正比，与管道长度的1/4次幂成反比。

They are used to move gas or liquid from one pressure are to another pressure area.

它们被用来移动气体或液体的压力是从一个到另一个压力区。

When meteorite hit the Earth surface, it created shockwave to transfer the kinetic energy to the Earth surface. When the speed of meteorite strike reached 10 km/second, the pressure of shockwave can reach several millions bar to compress the target terrane to produce heat, the effect of impact deformation caused by it is several scales stronger than rock intensity, the granite would melt down once the pressure of shockwave reached about 500 thousands bar, the granite would gasify (solid became liquid and meanwhile further became gaseity) once reaching over 600 thousand bar.

当陨石撞击地表时产生冲击波把陨石的动能传给地表，在陨击速度达到10公里/秒时冲击波的压力可达到数百万巴并压缩靶点岩层物质产生热，它产生的冲击变形效应比岩石强度大几个量级，冲击波压力约50万巴时花岗岩就熔化，大于60万巴时花岗岩就气化（在固态转为液态同时进一步转为气态）。

As to the content of the research, through the combination of generic and special, point and face, the study surrounds the structure, characteristics and formation of psychological stress and coping ways, takes a comprehensive and systemic research on the problem of ethnic minorities\' psychological stress and coping.

5在研究内容上，围绕着心理压力与应对方式的结构、特点和成因逐层推进，其间通过一般与特殊、点与面相结合的方式对西南少数民族心理压力与应对问题进行了比较全面和系统的考察。

If average values before or after catastrophe point when the pressure at both ends reduces exceed the threshold value, judging that there is leak and positioning: calculating approximate wavelet transformation coefficient of pressure data at both ends, initializing searching interval, calculating a signal time delay value corresponding to approximate wavelet transformation coefficient in the searching interval from maximal scale N; converting the time delay value under scale N to that under N-1 by geometric proportion relation; updating the searching interval, repeating above processes until the scale is 0 and positioning based on the time delay value.

若两端压力下降突变点前后的均值变化均超过阈值，判定有泄漏并进行定位：计算两端压力数据的近似小波变换系数，初始化搜索区间，从最大尺度N开始在搜索区间内计算对应近似小波变换系数的信号时延值，利用等比关系将尺度N下的时延估计值转换为N-1下时延估计值，以该值更新搜索区间，重复以上过程至尺度为0，以此时延估计值进行定位。

Solitude in fact is the oneself give oneself exert of a kind of pressure, positive so-called inside because of decision outside because of, not the oneself gives the oneself even to add a kind of pressure, toing believe the solitude to is a person to break of, many and the external world contact, thus just not standing alone, and there will be more happy and substantial oneselfs!

孤独其实是自己给自己所施加的一种压力，正所谓内因决定外因，不要自己给自己平添一种压力，要相信孤独是人来打破的，多和外界接触，这样才不会孤独，而且会有更多的快乐充实自己！

What is the Cv of a 12 inch Class 900 Pacific pressure seal globe valve 1/4 open?

例： DN300，压力等级Class 900的美国太平洋压力密封截止阀在开心胸为1/4时的流量系数是多少？

I was stress out and one of the best thing to ease your stress is to go out of town.

我是压力，并且对最好的东西，以减轻你的压力之一是出城去。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
