我们对经典点粒子通过r（-12）排斥对势相互作用的二维系统进行了计算机模拟，研究了熔化相变。随着密度的增加，平衡系统在低于平衡晶体中可达到的最低值的压力下发展出六角有序。键的取向顺序和平移顺序的有限尺寸标度分析给出的相关性在六角和固体，是一致的Kosterlitz的Halperin-Nelson-Young图片的指数。
We have performed computer simulations for a two-dimensional system of classical point particles interacting via an r(-12) repulsive pair potential to study the melting transition. As the density is increased, the equilibrium system develops hexatic order at pressures lower than the lowest values achievable in an equilibrium crystal. Finite size scaling analysis of the bond orientational order and translational order gives exponents for correlations in the hexatic and solid that are consistent with the Kosterlitz-Thouless-Halperin-Nelson-Young picture.
