摘　　要：用原子团簇理论和完全量子力学计算，研究了固氦和固氢的等温压缩线．在固氢的分子间相互作用势计算中，采用了球形势近似和等效氦原子模型．计算结果与１００ＧＰａ以下的实验等温线相比较。Abstract Based on the atomic cluster theory and quantum mechanics, the isothermal curves of solid helium and solid hydrogen have been calculated. In the calculation for solid hydrogen, the spherical potential approximation suggested by Cui et al. and the effective helium atomic model of ours were adopted. Comparisons of the theoretical results with the avialable experimental data, which are all below 100GPa, were made and it was found that they are in good agreement with each other
