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。

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.

根据这一定律，在热气体与冷气体的自发混合、气体向真空的自由膨胀以及燃料的燃烧之类的不可逆过程中，熵都是增加的。

The law states that entropy increases during irreversible processes such as spontaneous mixing of hot and cold gases, uncontrolled expansion of a gas into a vacuum, and combustion of fuel.

研究一种快速测报铝合金针孔度的方法。该方法是在铝合金凝聚固过程中，通过测量其因氢析出所产生的自由线膨胀而进行针孔度预测的。

The authors recommend a way for estimating the percentage of pinhole in solidified aluminum alloy by measuring its free linear expansion during the solidification.
