摘要
通过几个矩阵形式的微分恒等式，建立了几个关于二阶自共轭微分系统（Ｐ（ｔ）Ｙ′（ｔ））′＋ Ｑ（ｔ）Ｙ（ｔ） ＝ ０的预备解及其导函数的Ｓｔｕｒｍ 比较定理，推广了若干经典结论。
To utilize a few of matrix differential identies,in this paper,we establish some sturm comparison theorems of prepared solutions and derivative function of prepared solutions for second order selfadjoint differential system (P(t)Y′(t))′+Q(t)Y(t)=0,and generalized some classic results.
