压缩气体

Therefore, when the piston is pushed up in the cylinder, the air in the cylinder is trapped above the piston and compressed.

因此，当活塞在气缸里被推动向上时，气缸内的气体便被集聚在活塞上面并被压缩。

Propane is a three- carbon alkane , normally a gas, but compressible to a transportable liquid.

丙烷是一种三碳烷烃，通常是气体，但可压缩到运输的液体。

Most of the students wrote proofs of their beliefs using Boyle's law (gas cools off when it expands and heats up when it is compressed), or some variant.

绝大部分的学生都是用波义耳定律（即：在定量定温下，理想气体膨胀冷却，压缩变热。）或者一些变量来证明。

大部分学生应用波义尔定律(气体膨胀时变冷而被压缩时变热)或其变型来证明他们的看法。

In short, because of water ring pump gas compression is isothermal, and it can be pumped in addition to flammable and explosive gases.

总之，由于水环泵中气体压缩是等温的，故可以抽除易燃、易爆的气体。

Because of the connecting rod is one of dyadic engine of piston and main compression engine part, whose larger end hole and crank shaft link up , the small head hole links up by the wrist pin and the piston , whose effect is that the piston gas pressure is transmitted to the crank shaft , collect crank shaft gas in driving but setting a piston in motion to compress a cylinder.

本文主要论述了液压设计。因为液压是活塞式发动机和压缩机的主要零件之一，其大头孔与曲轴连接，小头孔通过活塞销与活塞连接，其作用是将活塞的气体压力传送给曲轴，又收曲轴驱动而带动活塞压缩汽缸中的气体。

因为连杆是活塞式发动机和压缩机的主要零件之一，其大头孔与曲轴连接，小头孔通过活塞销与活塞连接，其作用是将活塞的气体压力传送给曲轴，又收曲轴驱动而带动活塞压缩汽缸中的气体。

The center compresses enough to become a protostar and the rest of the gas orbits/flows around it.

三、中心的尘埃气体压缩到能够形成原恒星，剩下的气体在其周围围绕或流动。

The compression process difference between real and perfect gas model is also compared in the case of equal specific volume ratio .

使用实际气体模型对R134a在半开式离心压缩机叶轮内部三维湍流进行了数值计算，比较了比容比相等情况下实际及理想气体模型对压缩过程的差异。

The quasi-3D S〓/S〓 streamfilaments iterative computation is used to analyse the flow field in centrifugal impellers compressing perfect gas and real gas respectively.

使用准三元S2/S1流面迭代计算，对压缩理想气体和实际气体的离心叶轮流场作了分析。
