压力

Owing to pump, when the liquid flow out of the impeller, its speed energy and stress energy both develop much, the liquid debarred by the impeller , most speed energy is transferred to stress energy ,and then it is transported through pipeline .At this moment ,the entry of the impeller become vacuum or low-pressure , hydraulic pressure effect on the liquid in the absorbing pool, and the liquid is pulled into the entry of the impeller , so ,the rotating impeller continuous inhalants and Drainage liquid.

由于泵的作用液体从叶轮进口流向出口的过程中，其速度能和压力能都得到增加，被叶轮排出的液体经过压出室，大部分速度能转换成压力能，然后沿排出管路输送出去，这时，叶轮进口处因液体的排出而形成真空或低压，吸水池中的液体在液面压力的作用下，被压入叶轮的进口，于是，旋转着的叶轮就连续不断地吸入和排出液体。

In this paper, an idea is presented about a larger pressure of percolation flow existed in a part of rock by a high-pressure jet, and the pressure has great effect on the rock fragmentation with jet. A model of calculating the pressure is established.

本文提出了射流作用下岩石局部范围具有较高渗流压力的思想，并认为该渗流压力大小对射流破岩有重要影响，建立了该渗流压力的计算模型。

To adjust pressure setting, loosen the lock nut and turn the adjusting bolt clockwise to increase pressure, counter clockwise to decrease pressure.

要调节压力设置，先松开锁紧螺母，然后顺时针旋转调节螺栓以增加压力，逆时针旋转以降低压力。

To adjust pressure setting, loosen the lock nut and turn the adjusting bolt clockwise to increase pressure, counter clockwise to decrease pressure.

为了调节压力设置，要松开锁紧螺母，顺时针旋转调节螺栓增加压力，逆时针旋转降低压力。

Thepressure history of the porous bed bottom was measured by use of a strain-compensated manganin gage.

利用测压系统对DDT流场尾部的压力进行了直接测试，得到了流场的压力波形及压力值。

From the results, we can analyze the stability of Manganin wire's resistance, and discuss the similarity between the zero-pressure resistance changes and the characters of pressure versus resistance.

本实验结果的分析，首先，拟探讨各加工条件下电阻变化的大小，接著再讨论 Manganin 压力计电阻的压力系数大小，最后，电阻安定性的分析包括了起始电阻的偏移和压力－电阻变化的关系之一致性。

Manganin pressure gauges used in this study are processed by temperature and pressure seasoning, coil sealing, and the fixation of pressure gauge.

本研究中的 Manganin 压力计经过缠绕、温度季化、线圈之封装和压力季化的过程而制作完成，并以直接加压法校正 Manganin 压力计。

The biggest characteristic of this model is that the hydraulic system pump station, operating console and working clamp installation table can be installed and connected in users sites and dived the test workpiece into the pond, can lift up and down, left and right two directions clamp worktables set 90 degree overturn function, especially suitable for gas pressure test.

本机型最大特点由液压系统泵站，操作控制台和工作夹紧装置台在用户现场安装连接，将试验工件潜入水池中目测，可上下升降，左右两向夹紧工作台设有90度翻转功能，特别适应气体压力试验。◎适用于直通法兰式阀门的密封压力和阀体强度压力性能试验。

Pressure trapping unloaders react only to pressure in the system and give you instant pressure when you open the trigger gun.

压力集及型减压器只对系统的压力作出反应，并且当你开起扳机时，就会顺势产生压力。

The spike pressure increases with the unloader setting until it becomes so great that damage begins to occur in the system broken hoses, blown valve caps, leaking unloaders and so on.

当减呵器将水引至旁路时，就会减荷器的压力就会高于其设定压力，如果压力太大，就会损坏泵；软管爆裂，阀盖炸开，减压器泄露等。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
