摘要: <正> 一、引言目前高分子材料耐腐蚀性能的测定主要采用静态浸泡法,虽然其数学处理简便,但往往不能反映真实情况,动态耐腐蚀研究是今后发展的方向,它能较真实地反映高分子材料内存在温度梯度时的介质扩散情况。奥田聡曾对在温度梯度下渗入介质的浓度分布与着色深度关系作过报导。

Abstract：Diffusion of the medium in the polymer plate material of the lining with variable thermo-diffusivity was discussed in-the paper. By means of weighted residuals, a general approach for the N-th approximation was achieved. The second approximation of the concentration was achieved, and the relation between the temperature and the plate life time was established on the basis of specific examples.
