我们利用分子动力学计算机模拟技术，研究了二维流体与Lennard-Jones势相互作用时凝固区的开始。我们研究了成对分布函数g(R)及其傅立叶变换S(Q)，以获得与冻结开始有关的唯一、定性和定量的结构特征以及普遍冻结准则的有效性。我们得出的结论是，这样的判据是存在的，但它的值对密度和温度的微小变化都很敏感。
We have investigated, employing the techniques of molecular-dynamics computer simulation, the onset of the freezing region of a two-dimensional fluid interacting with a Lennard-Jones potential. We have studied the pair-distribution function g(r) and its Fourier transform S(q) for unique, qualitative, and quantitative structural characteristics associated with the onset of freezing and for the validity of a universal freezing criterion. We conclude that such a criterion exists, but its value is sensitive to even slight changes in density and temperature.
