摘要
研究了一类具有套层现象的奇摄动微分方程的初值问题 .利用微分不等式理论 ,证明了问题解的一致有效性 .
In this paper, the author discusses the cover layer solution of the singularly perturbed initial value problem for differential equation and proves the uniform validity of the solution for the original problem by using the theory of differential inequality.
