待定法在求解某些变系数常微分方程中的应用

Application of Method of Undetermined Coefficients in Seeking Solution of Certain Variable Coefficient Ordinary Differentical Equations

分析了变系数常微分方程的特点，提出了两种形式变换的待定法求解某些特殊的变系数常微方程的方法，以实例验证了此法的应用．

In this paper,the feature of variable coefficient ordinary differentical equations is anaylised. The method is put forward which method of undetermined coefficients of two formal transformations seek solution of certain special variable coefficient ordinary differentical equations,however,the application of this method are demonstrated by examples.
