近几年来，对固态氩的热力学性质进行了测量，为晶格理论的验证提供了理想的材料。本文从晶格的基本问题出发，评述了惰性气体晶体的动力学和热力学。当计算是基于具有（12，6）原子间作用势的非简谐爱因斯坦理论时，在许多情况下理论和实验之间获得了令人满意的一致性。它示出，进一步的进展需要，特别是，延长实验到较低的温度和理论计算的排斥氩原子到一个更高的近似。
In the last few years measurements have been made of the thermodynamic properties of solid argon which provide ideal material for the verification of the theory of crystal lattices. Starting from the basic problem of the crystal lattice, a review is given here of the dynamics and thermodynamics of the inert gas crystals. Satisfactory agreement is obtained in many cases between theory and experiment when the calculations are based on an anharmonic Einstein theory with a (12,6) interatomic potential. It is shown that further progress requires, in particular, the extension of experiments to lower temperatures and of theoretical calculations of the repulsion of argon atoms to a higher approximation.
