在不假定非线性项非负的情况下，利用半序理论讨论了Ｈａｍｍｅｒｓｔｅｉｎ型积分方程非零解的存在性，并将所得结果应用于常微分方程两点边值问题．

in the case of not requiring the nonlinear terms non-positive, the existence of nontrivial solutions for the Hammerstein Integral Equations by using the partial ordering theory was discussed and some applications to ordinary differential equations with two-point bounded values.
