检查气体量的方法,瓶装气体现有气态、液态两者区分;-氧气、氮气、氩气、氢气、氦气、空气为气态气体;-乙炔气为气态溶解在丙酮之中;-液氨、二氧化碳、笑气等为液态气体;-检查气态气体是否符合满瓶,检查方法是用压力表测试气瓶的显示压力。

然后对这些气体的浓度增升进行分析,以得出某个给定表面区域所释放的气体量。
Rising concentrations of these gases are then analysed in order to draw conclusions about the amount of gas being given off by a given surface area.
And we saw that in fact in this case delta S of mixing, we calculated it, saw that it is positive.
实际上如果我们计算气体混合过程中,熵的变化,我们会发现这个量是正的。
