刘维尔方程在推导用相互作用粒子近似的物理系统的连续模型中具有根本的重要性。然而,当粒子经历瞬时相互作用(如碰撞)时,刘维尔方程的推导必须适用于排除非物理粒子位置,并包括瞬时相互作用的影响。本文给出了具有一般粒子动力学和相互作用的相互作用粒子的刘维尔方程的弱形式,并通过两个例子讨论了结果。
The Liouville equation is of fundamental importance in the derivation of continuum models for physical systems which are approximated by interacting particles. However, when particles undergo instantaneous interactions such as collisions, the derivation of the Liouville equation must be adapted to exclude non-physical particle positions, and include the effect of instantaneous interactions. We present the weak formulation of the Liouville equation for interacting particles with general particle dynamics and interactions, and discuss the results using two examples.
