摘要
在传统的《热学》教材中,通过先分别考虑分子引力作用产生的影响和分子斥力作用产生的影响,再综合考虑分子力作用产生影响的方法推导焦耳-汤姆逊效应的转换温度,得到的理论值与实验值相差较大.给出了计算焦耳-汤姆逊效应转换温度的一种方法,由这种方法得到的理论值与实验值相差较小.
In the tradition Heat Studies in the teaching material, through separately considered first the molecular attraction function produces the influence and the molecular repulsion function produces the influence, then the overall evaluation member action of force produces the influence method inferential reasoning Joule-Thomsen effect transformation temperature, obtains the theoretical value and the actual value difference is big, given the computation Joule-Thomsen effect transformation temperature one method. The theoretical value and the actual value difference obtains which by this method is small.
