非线性扩散方程的一个新的近似解
A New Approximate Solution of Nonlinear Diffusion Equation
-
摘要: 本文研究了文献[1]中的同样问题.本文作者的解近似地满足全部基本方程(1.1)和(1.2)和全部边界条件(1.3)～(1.5).而刘氏的解却不满足连续性方程(1.2).Abstract: In this paper, the same problem in ref. [1] is studied. The author's solution approximately satisfies the whole fundamental equations (1,1) and (1.2), and the whole bound values conditions (1.3-1.5). But the Liu's solution(1) does not satisfy the equation of continuity (1.2).
