摘要
研究了一类非线性常微分方程的非平凡解及其死核问题，证明了在参数ｐ的某些取值范围内，该问题存在非平凡解且具有死核；但在ｐ的另一些取值范围内。
The existence of a nontrivial solution and its dead core problem for a class of nonlinear ordinary differential equations are studied.This problem has a nontrivial solution which has a dead core for some parameters but for another some parameters p, this problem has not any nontrivial solution.
