摘　　要：研究了方程 y″(x) +p(x) y(x) =f(x)振荡解的充分条件 。It reserched on equation y″(x)+p(x)y(x)=f(x) oscillatory solution. Ample reasons are given for this equation oscillatory solution and nonoscillatory solution being positive solution, and, essential condition are given for this equation nonoscillatory solution being positive solution and advance little by of nonoscillatory solution.

关 键 词：振荡解 非振荡解 正解
