摘要 运用靶向法研究了一类非线性二阶常微分方程三点积分边值问题正解的存在性.通过构造一个二次函数及一个正弦函数做为目标函数,并结合使用积分中值定理及Sturm比较定理,得到了上述边值问题存在正解的充分条件. Using the method of shooting, the existence of positive solutions for a class of second-order three-point integral boundary-point problem is studied. By constructing a quadratic function and a sine function as the objective functions and combining with the In- tegral Mean Value Theorem and Sturm Comparison Theorem, we obtained the sufficient conditions for the existence of positive solutions to the boundary-value problem.
