摘要
本文讨论了较一般的一类具有转向点曲线的奇摄动椭圆型方程的边值问题 ,利用多重尺度法和比较定理 ,研究了边值问题解的一致有效渐近近似式 .
In this paper, we study a class of singularly perturbed elliptic equation boundary value problem on a curve with turning point by using the method of multiple scales and the comparison theorem. The uniformly valid asymptotic approximations of solution for the boundary value problem is studied.
