摘　　要：综合运用Nevanlinna值分布的理论,Wiman-Valiron的理论及其它复分析中的常用方法研究了复域上高阶微分方程解带有小函数时复振荡的性质,该文的结果将二阶情形推广到高阶情形。In this paper, we mainly use the Nevanlinna value distribution theory, complex oscillation properties of Wiman-Valiron theory and other complex analysis method to study the characteristics of higher order ordinary differential equation with a small function in complex domain.The results of this paper extend the second-order case to the higher-order case.
