摘要翻译:
在一个非相互作用的布朗粒子系综中,有限的系统平均速度可能暂时发展起来,即使它最初为零。这种影响源于对耗散力的一个小的非线性修正,导致速度一阶矩方程耦合到高阶矩。当复杂系统在动量守恒的粘性介质中解离时,这种效应可能是相关的。

英文摘要:
In an ensemble of non-interacting Brownian particles, a finite systematic average velocity may temporarily develop, even if it is zero initially. The effect originates from a small nonlinear correction to the dissipative force, causing the equation for the first moment of velocity to couple to moments of higher order. The effect may be relevant when a complex system dissociates in a viscous medium with conservation of momentum.
