关于 Package的选择。 大家来讨论讨论？ 回复 4# lty 这就是我的一个作业 实在想不出。 和同学讨论的结果是 用prsv “peng-robinson：this model is ideal for vle calculations as well as calculating liquid densities for hydrocarbon systems. however, in situations where highly non-ideal systems are encountered, the use of activity models is recommended.” "peng-robinson-stryjek-vera this is a two-fold modification of the pr equation of state that extends the application of the original pr method for moderately non-ideal systems. it provides a better pure component vapour pressure prediction as well as a more flexible mixing rule than peng robinson." 以上两段话来自《aspencomthermov7_1-ref》。 解释的话 ，丙酮 极性大，应该不能算理想体系吧。prsv 是pr 的进化版。 才刚入了点门。教授说选择给出理由就好。 所以 我想选prsv 再稍微写写 应该差不多~ 谢谢你的帮助了、查看更多
