摘要
本文研究了几类广义系统，得出了一类广义线性非齐次系统存在周期解的充要条件，一类广义线性时变系统存在唯一周期解的充分条件；一类广义非线性系统存在周期解的充分条件．
In this paper, singular systems of several classes are studied. We obtain the necessary and sufficient condition which singular systems of a class exist only one periodic solution. the sufficient condition which singular linearsystems of variable time exist only one periodic solution and the sufficient condition which singular nonlinear systems ofa class exist only one periodic solution.
