An Exact Solution of the Fokker-Planck Equation
摘要: 本文首先利用一个变换将描述肿瘤增长模型的Fokker-Planck方程转化为常微分方程，然后利用F-展开法和Mathematica软件构造出方程的一个精确解，最后描绘在不同参数情形下解的图像来展示解的性态。
Abstract:
We first use a transform to convert the Fokker-Planck equation describing the tumor growth model into an ordinary differential equation, then construct an exact solution of the equation by means of the F-expansion method and Mathematica software, and finally draw the figures of the solutions under the different choosing parameters to demonstrate the behaviors of the solutions.
