气体的绝热节流过程不是等焓过程

Adiabatic Throttling Process of Gas Is Not Isoenthalpic

说明气体的绝热节流过程不是等焓过程 ,指出用焦 -汤系数 μ= T p H来说明焦耳 -汤姆孙效应所存在的弊端 。

It is pointed out that the adiabatic throttling process of gas is not an isoenthalpic one and that there are some drawbacks for interpreting the Joule Thomson effect with the Joule Thomson coefficient μ=  T  p H . A proper interpretation for the throttling process is given.
