在考虑自由气体存在的影响下，推导出浆体水击压力波波速的计算公式。

Taking account of the effects of free gaseous phase, the mathematical formulations are presented to describe the pressure wave speeds of transient flow in slurry pipelines.

虽然它作为自由气体在大气中的寿命比二氧化碳要短的多，但要说吸热能力，它比后者强23倍。

Although its lifetime in the atmosphere as a free gas is much shorter than CO2, it is 23 times more potent in terms of its heat trapping ability.

第一个，或许是所涉及到的最简单的一个，就是气体的自由扩散。

And the first one, the simplest one, maybe, to cover, is just free expansion of a gas.

So the Joule free expansion involves opening this valve and asking what happens when this gas moves into the other bulb or distributes between the two.

焦耳自由膨胀就是,打开阀门后的过程,气体从一个腔跑到另一个腔,并在它们之间平均分配。
