摘要 本研究了一类非线奇摄动人口问题.在适当的条件下,首先求出了原问题的外部解,然后利用伸长变量和幂级数展开理论构造出解的形式渐近展开式.最后利用微分不等式理论,讨论了问题解的一致有效性. A class of nonlinear singularly perturbed population problem is considered.Under some suitable conditions,firstly,the outer solution of the original problem is obtained, secondly,using the stretched variable and the expanding theory of power series the formal asymptotic expansions for the solution is constructed,and finally,using the theory of differential inequalities the uniform validity of the solution are studied.
