摘要 研究了二阶线性微分方程f″+A1eazf'+A0ebzf=0和f″+A1eazf'+(A0ebz+A2edz)f=0的解的无穷级射线,是在前人研究结果的基础上的又一结果。 In this paper we investigate the rays of infinite order of linear differential equations f″+A1e^azf′+A0e^bzf=0 and f″+A1e^azf′+(A0e^bz+A2e^dz)f=0 and this is another result on the basis of predecessors'research.
