In this paper,the maximum principlscs of some functional solutions of a class of asemilinear parbolic equations are derived,The principles may be used to prove somenonexistence theorems of global solutions for the parbolic problcms under certainassumptions tions and estimate the bounds of blow-up time.
借用这些极值原理，不仅可获得在一定条件下该类抛物型问题整体解的不存在性，而且可给出解的破裂时刻估计。
This paper studies the formal similarity of solutions of a type of ordinary differential equations with closed right boundary conditions and the left boundary conditions with respect to independent variable r.
本文作者研究了一类常微分方程组在定值右边界条件和随自变量r变化的左边界条件下解的结构,从结构中可以清晰看出方程组中出现的参数对解的影响,能帮助人们认识模型遵从的内在规律,从而更加方便简单的编制相应的分析软件。
