During the pumping cycle the gas is in intimate contact with the sealing liquid and compression is nearly isothermal.
在抽运周期内，气体会与密封液和几乎等温的压缩气体紧密接触。

Further, the principles and ways which solve the crucial question are given, that is, two supports consisted of three-ball bearing are combined with the sealing by differential gas flow cycle.
进而阐述了解决这些关键问题的原理和方法，即两个三滚珠轴承支承和差动气流循环密封相结合的方法。

Because of the action of an outer cover and a sealing gasket in the inside, the change cycle can be extended largely by the water in the tray of the jar body, and the water is not easy to vaporise.
