摘要
在二阶线性微分方程Sturm比较定理的基础上,利用Picone恒等式,给出一类三阶线性齐次微分方程的Sturm比较定理,所得结论推广了现有文献的结果。
In the second order linear differential equation Sturm comparison theorem＇s foundation,by using the picone identical equation＇s,a kind of third order linear homogeneous differential equation was given the Sturm comparison theorem.Some results were generalized.
