摘要
通过把系数含有负三次幂函数与排列数的交错级数型线性微分方程化为可逐次积分的线性微分方程,找出了求这类方程通解的方法与理论,把所得定理给出了严格的证明,并将其推广,同时通过实例介绍了它的应用。
Throush the interlace series type linear differential equation, coefficient containing three negative number of times, power function and arrangement number can be changed into the linear differential equation of successive integral. The theory and method showed this kind of equation is to untie and happened to have given strict proof,and application.
