摘要

摘要: 研究了一类非线性催化反应微分方程Robin问题.在一定的条件下，先利用摄动方法求出了原Robin问题的外部解，然后用伸长变量和幂级数理论分别构造了解的第一和第二边界层校正项，从而得到了Robin问题解的形式渐近展开式.最后利用微分不等式理论，证明了问题解的渐近表示式的一致有效性.

Abstract: A class of Robin problems of nonlinear catalytic reaction differential equations were studied. Firstly, under the suitable conditions, the outer solution to the original Robin problem was obtained with the perturbation method. Then by means of the stretched variable and the power series, the 1st and 2nd boundary layer corrective terms were constructed respectively, and the formal asymptotic expansion was structured. Finally, based on the theory of differential inequalities the formal asymptotic expression of the solution to the Robin problem was given. Finally, the uniform validity of the asymptotic expression of the solution to problem was proved.
