英文摘要：

Properties of meromorphic solutions of a second order linear differential equation with meromorphic coefficients of [p,q]-φ order are investigated by using Nevanlinna＇s value distribution theory of meromorphic functions.And some results on the relations between the order of meromorphic solutions,the convergence exponent of（ distinct） zeros and（ distinct） poles of meromorphic solutions,and the order of the coefficients are obtained,which are improvements and extensions of the corresponding results of previous papers.
