In the figure, the system will travel along the valley ( R), over the saddle point ( Q), and down into the second valley ( P). The reaction path is represented by R Q-P line.
反应体系的代表点从山谷R沿反应途径爬过鞍点Q后落入另一山谷P中(R-Q-P线就代表反应途径)。
In this paper, the two dimensional Fokker-Planck Equation is exactly solved by means of the numerical method. The velocity distribution at the saddle point, the second moments of the coordinate and velocity, the time development of the nuclear fission rate are studied.
本文应用数值方法严格求解二维福克-普朗克(Fokker-Planck)方程,研究在鞍点上的速度分布、坐标和速度的二次矩以及核裂变速率随时间的演变。
