【摘要】 发展了一种用变分法解Ｆｏｋｋｅｒ－Ｐｌａｎｃｋ方程的方法，计算了一维核裂变几率，研究了Ｆ－Ｐ方程与Ｓｍｏｌｕｃｈｏｗｓｋｉ方程的关系，为推导多维的质量系数和粘滞系数随形变参量变化并具有交叉项的Ｓｍｏｌｕｃｈｏｗｓｋｉ方程和解位能形式比较复杂的多维的Ｆ－Ｐ方程打下了基础。更多还原

【Abstract】 A variational method is developed to solve Fokker-Planck (F-P) equation. One dimensional fission probability is calculated and compared with other methods. The relation of F-P equation and Smoluchowski equation is discussed in light of thismethod, which gaves the way to derive the multi-dimensional Smoluchowski equation with varying mass and viscosity and to solve more complicated F-P equations.更多还原
