摘要
讨论了一阶非齐时变线性系统解的渐近性和振动性，得到了两个充分条件和必要条件．对一般的非线性系统得到了一个必要条件．
The oscilation and asymptotic behavior of solutions for the first order linear functional differential equations with oscillatory coefficients are discussed. A sufficient condition and a necessary condition of solutions with asymptotic behavior are obtained,and a necessary condition is obtained for the general nonlinear systems.
