摘要
本文由Ｌｉｎｄｅｍａｎｎ定律出发，利用Ｄｅｂｙｅ模型和Ｖｉｎｅｔ方程拟合计算了四种碱金属Ｌｉ、Ｎａ、Ｋ和Ｃｓ在高压下的熔解温度，并与Ｓｉｍｏｎ方程的计算结果进行了比较。结果表明，就与实验值的符合程度而言，前者的计算结果好于Ｓｉ－ｍｏｎ方程的结果。
Starte from Lindemann’s law,the melting temperature of 4 alkali metals (Li,Na,K and Cs)under high pressure are fitted and calculated using the Debye model andVinet equation. The calculated results are compared with that obtained by Simon eua-tion. As far as the agreement with the experimental data is concerned, the comparisonindicates than the former calculated values are better than that obtained by Simon equa- tion.
