摘要
本文利用室温下21种化合物的压强与体积压缩比的实验数据,以及对于NaCl和CsCl在不同温度下压强和体积压缩比的实验数据,对Kumari-Dass方程和Vinet方程的普适性作了检验和比较。结果表明,就普适性而言,K—D方程优于Vinet方程。
In this papetr,the universality of both Vinet equation and Kumari—Dass (K—D)equation is tested and compared using the compressibility data for 21 compounds at room temperature as well as for NaCl and CsCl at various temperatures . The results indicate that,as far as the universality is concerned,the K—D equation is better than the Vinet equation.
