Abstract:: This article mainly solves two problems with the variable coefficient linearly differential equations with characteristic heavy root types: ① If the type of equation has Y heavy characteristics roots, this type of equation can be reduced to N Y -level equations at one time, and the principle of reduction of the constant coefficient equation is promoted. ② This type of equation can find some special solutions on the premise of not knowing any features in advance.
