关于PT，见同上，第15卷，第2801页（1982）。本文基于模式耦合理论，给出了高密度下经典硬球流体的密度、横向流和能量密度相关函数的数值结果。的结果进行了比较与广义Enskog理论的近似解和分子动力学实验的结果。作者发现，传播的剪切波以上的临界波数和缓慢衰减的密度相关函数在中间波数，这两个新的定性特征是一致的分子动力学结果。
For pt.I see ibid., vol.15, p.2801 (1982). Numerical results for the correlation functions of density, transverse current and energy density of a classical hard-sphere fluid at high density are presented based on a mode-coupling theory developed in a previous paper. The results are compared with an approximate solution of generalised Enskog theory and with results of molecular dynamic experiments. The author finds propagating shear waves above a critical wavenumber and a slowly decaying density correlation function at intermediate wavenumbers, both new qualitative features being in agreement with molecular dynamic results.
