摘　　要：研究了二阶摆型振动方程奇调和解的存在性.运用Schwarz不等式估计方程解的先验界技巧和Leray-Schauder度理论得到了方程奇调和解的存在性定理,将Mawhin所给出的力函数周期性条件减弱为线性增长条件,从而改进了JMawhin的结果.The existence of odd-harmonic solutions for a second order pendulum-type oscillation equation was studied. The existence theorems of solutions were obtained by using the technique of Schwarz's inequality to take prior estimate for solutions of the equation and the Leray-Schauder degree theory. In addition, the periodic condition for a force function given by Mawhin was weakened to the condition of linear growth. As a result, the some relative results given by J Mawhin were improved.
