在本文中，我们考虑的自相互作用的粒子云在一个固定的势场的存在下的演变。设f（x，v，t）为位置-速度相空间中的云的单粒子分布（或质量分布）。用U（x，t）表示云在点x· R ′ ′和时间t·~+处通过自相互作用产生的电势，
In this paper we consider the evolution of a self-interacting cloud of particles in the presence of a fixed potential field. Let f (x, v, t) be the single-particle distribution (or the mass distribution) of the cloud in the position-velocities phase space R,~® Ro~. Denote by U (x, t) the potential induced by the cloud at a point x• R~'and time t•~+ via self-interaction,
