When the balance of the piston, the pressure difference between the two parts form a cavity upward oil pressure and spring pressure, friction, balance piston weight in balance, the balance of the piston to maintain a certain distance from opening up.

当平衡活塞上、下两腔压力差形成向上的油液压力和弹簧压力、摩擦力、平衡活塞自重处于平衡状态时，平衡活塞上升距离保持一定开度。

Then, to incorporate non-linear earth pressure gradual change theory, to get non-linear earth pressure all spring elastic ground beam method which is related to wall deviation direction and magnitude.

然后结合非线性土压力渐变理论，得出非线性土压力全弹簧的弹性地基梁法，该法与墙体变位方向与大小均有关。

There is much difference between the stress ratio in crown and springe calculated with these two methods. In the crown, most external forces changing into horizontal forces leads to the large decrease of the vertical tension stress. The vertical distribution pattern of the axial forces in the arch and soil pressure is not the same. And near the bottom of the pit the axial tension stress appears. Due to the self-accommodation effect which the external force acts on the arch, the stress in the springe gets lesser too.

拱冠和拱脚处的应力比值跟竖向构件比较相差悬殊；拱冠处由于大部分外力转化为水平拱内轴压力而使得竖向拉应力大大减小；竖向上拱内轴力与土压力的分布模式并不相同，并且在坑底附近出现了轴拉力；拱脚处也由于拱体对外力的自我调节作用而变得比纯竖向构件小的多。

Second, classified by main parameters by pressure classification Working pressure vacuum valve below the standard atmospheric pressure valve.

二、 按主要参数分类按压力分类真空阀工作压力低于标准大气压的阀门。

According to nominal Check Valves pressure classification (1) Vacuum Valve: refers to the pressure below standard atmospheric pressure valve.

按公称压力分类(1)真空阀：指工作压力低于标准大气压的阀门。

The design presented here is a hydraulic unit that converts thrust force of the rocket motor to hydraulic pressure, which may be displayed with the use of a standard pressure gauge.

设计在这里是一个液压装置转换为推力的火箭发动机液压压力，可能会显示与使用一个标准的压力计。

Results show that with the increase of the apparent gas velocity in the riser,there is little change in negative pressure gradient in the standpipe.

结果表明：随着提升管内表观气速的增加，立管内的负压差梯度变化不大；而随着系统循环量的增加，立管内的负压差梯度以及滑移速度均增大；随着加入热解室内松动气量的增加，立管内尤其是立管上部的压力也随之增大，热解室内无论是移动床流动还是流态化流动均对立管的稳定性影响不大；但当热解室内的压力超过某一值时，立管内的料封很快被破坏，导致系统无法运行。

The discussion is focused on the determination of the minimum air rate when there is reservoir fluid influx during air drilling, injection pressure at standpipe, and bit nozzle pressure.

应用气体状态方程、热力学定律对空气钻井中各个流动参数进行分析，重点讨论储层流体涌入时空气钻井过程中最小空气流量的确定，以及立管注入压力和钻头喷嘴压力等问题。

When confined within a suitable pressure vessel, carbon dioxide can exist in any of three states of matter depending on conditions of temperature and pressure.

如果将二氧化碳装入一个可承受适当压力的容器内，只要温度和压力达到一定条件，二氧化碳就会发生固态，液态和气态三种不同状态的变化。

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.
