摘　　要：利用不动点指数定理讨论了一类二阶非线性常微分方程的三点边值问题正解的存在性,给出了边值问题正解存在的几个充分条件,最后给出了一个实例作为对所获得结果的应用.By applying the fixed point index theorem, the existence of positive solutions to a type of three-point boundary value problems of nonlinear second-order differential equations was discussed. Several sufficient conditions for the existence of positive solutions were given. Finally, an example was presented to illustrate the applications of the obtained result.
