摘 要: 本文研究了几类高阶线性微分方程解的增长性,零点,以及构成基础解的一组线形无关解的乘积的增长性.得到了5个定理,推广了陈宗煊,S.Bank和J.Langley给出的结果. In this paper, we investigate the growth and the zeros of solutions of some classes of higher order differential equations. We also investigate the growth of the product of a solution base of the equations and obtain five theorems which are improvements of related results given by Chen Z. X. , S. Bank and J. Langley.
