论文摘要
基于具有修改的边界条件的BBGKI方程链，该方程考虑了多粒子相关性，近似“对”碰撞中的动力学方程以及在极化近似中，考虑到通过第三个粒子获得的相互作用。考虑了通过短距离和远距离零件的粒子相互作用的模型表示的细节。如果以固体球的潜力形式的短距离潜力，则获得了Enskog修订的理论对动力学方程碰撞完全整合的贡献。碰撞积分包括依赖于粒子数密度和反向温度的非平均平均值的配对准平衡分布函数。集体变量的方法Yukhnovskii用于计算粒子相互作用的短距离和远距离零件的分配，以计算对准平衡分布函数。在这种情况下，具有短距离交互的系统被视为参考框架。
Based on a chain of BBGKI equations with a modified boundary condition that takes into account multiparticle correlations, kinetic equations in the approximate "pairs" collisions and in the polarization approximation, taking into account the interaction through the third particle, obtained. The specifics of the model representation of the pair potential of particle interaction through short-range and long-range parts were taken into account. In the case of the short-range potential in the form of the potential of solid spheres, the contribution of Enskog's revised theory to the complete integration of the collision of the kinetic equation is obtained. The collision integrals include paired quasi-equilibrium distribution functions that depend on the nonequilibrium mean values of the particle number density and the inverse temperature. The method of collective variables Yukhnovskii is applied for the calculation of pair quasi-equilibrium distribution function with an allocation of short-range and long-range parts in the potential of the interaction of particles. In this case, the system with short-range interaction is considered as a frame of reference.
