【摘要】 在本文(Ⅰ)报中提出的双阻力模型和质量通量准则的基础上,通过考虑任一微相和无序空间的相平衡,将径向分布函数用局部俘获率和局部位能解析性地表达出来,并解决了局部俘获率和局部位能的计算问题。由于计算公式的解析性,本文的计算速度远远高于分子模拟和积分方程理论。计算结果与分子模拟的结果吻合良好,在第1峰附近,优于积分方程的结果。更多还原

【Abstract】 Based on the double - resistance model and mass flux criterion proposed in part (Ⅰ) of this paper and by considering the phase equilibria between any one micro -phase and disorder space, the radial distribution function was expressed analytically in terms of local capture probability and local potential energy. The methods for calculating local capture probability and local potential energy were given. Because of the analyticity of the equations for calculating radial distribution function, much less computation time was needed than integral equation methods or molecular simulations. The results were in good agreement with those from molecular simulations. Better results were obtained than integral equations near the first peak.更多还原
