摘要翻译：
我们对方阱势的气液临界点进行了模拟研究，当阱宽δ小于0.005倍粒子直径σ时。对于较小的delta，临界点b2*c处的约化第二维里系数与delta成线性关系。由于临界温度T_c与B_2*c之间的高度非线性变换，如果通过常数B_2*c假设来估计T_c，所观察到的弱线性依赖不足以产生任何显著的可观测效应。这解释了先前观察到的相应国家法律的有效性。临界密度rho_c以两键合粒子间的立方平均距离(1+0.5δ)/σ为单位测量时也是常数。用精确的函数形式描述delta->0依赖关系的可能性提供了粘着硬球AHS模型临界参数的改进的累计估计。

英文摘要：
  We report a simulation study of the gas-liquid critical point for the square-well potential, for values of well width delta as small as 0.005 times the particle diameter sigma. For small delta, the reduced second virial coefficient at the critical point B_2*c is found to depend linearly on delta. The observed weak linear dependence is not sufficient to produce any significant observable effect if the critical temperature T_c is estimated via a constant B_2*c assumption, due to the highly non linear transformation between B_2*c and T_c. This explains the previously observed validity of the law of corresponding states. The critical density rho_c is also found to be constant when measured in units of the cubed average distance between two bonded particles (1+0.5 delta)/sigma. The possibility of describing the delta -> 0 dependence with precise functional forms provides improved acccurate estimates of the critical parameters of the adhesive hard-sphere AHS model.
