二阶线性微分方程的振动准则

Oscillation Criteria for Second Order Linear Differential Equations

讨论二阶线性微分方程（ｒ（ｔ）ｘ′）′＋ｐ（ｔ）ｘ′＋ｑ（ｔ）ｘ＝０的振动性，利用Ｒｉｃａｔｉ方程的形式特点，结合积分平均技巧，得到了新的判别准则，推广并改进了以往的若干结果．

By using the form of Ricattis equation and combining it with the technique of integral averages, oscillation criteria for second order differential equations (r(t)x′)′+p(t)x′+q(t)x= 0 are obtained. The results are generalizations and improvements of earlier results.
