摘　　要：考察一类二阶三点边值问题无穷多解的存在性.先利用分析上下解方法在共振与非共振两种情形下分别证明了上述问题解的个数可以是可数无穷多,并利用打靶法给出了此类问题的数值解法.Th problem. The singularity. F e authors constructed and analyzed an example of a second-order three-point boundary value authors considered the equation and the methods of solving the equation directed at t with the irst, the authors used the analysis of upper and lower solution method to prove this kind of problems in two resonance and nonresonance cases, respectively, to have infinitely many different solutions, and finally on the basis of the shooting method, the authors showed the numerical solution of this kind of problems.

关 键 词：三点边值问题 共振与非共振条件 上下解方法
