摘要
本文以氮气为例,讨论了合理地选择范德瓦耳斯修正常数a和b的问题,使范氏方程能在更大范围内更精确地描述实际气体的性质,获得了良好的结果。
A means of getting Van der Waals' constants a and b is discussed withnitrogen as an example. With the values of a and b which are amendedreasonably, Van Der Waals' equation can be more approximate to the case ofpractical gas in precision.
