Besides , two particular working conditions , filling a vessel with gas and sucking gas out of a vessel , are discussed in detail , and the equations for calculating the time for gas filling and suction are presented
在工程实践中，可根据实际气体的临界状态参数，查取其压缩性系数，计入实际气体的状态方程中，并将过程指数换成实际气体的容积绝热指数,这样就可把结论用于实践以解决工程问题。
