摘　　要：本文研究了一类二阶非线性微分方程解的振动性质,利用Riccati变换和某个不等式得到了保证方程一切解都振动的充分条件。In this paper, the author studies the oscillation of a second order nonlinear differential equations. Sufficient conditions for the oscillation of all solutions of the equation are obtained by using the Riccati transformation and certain inequality.
