【摘要】 研究了方程 y″(x) +p(x) y(x) =f(x)振荡解的充分条件 ,非振荡解为正解的充分与必要条件以及非振荡解的渐近性更多还原

【Abstract】 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.更多还原
