摘要
在研究一类二阶微分方程解的振动与渐近时,增加一个条件,即新方程中新出现项的系数函数与自变量同号,并且一阶连续可导,从而构成了新方程解振动与渐近的一个充分条件.
In the studying of the oscillatory and asymptotic behavior of solutions about a kind of second order differential equation, a new condition , namely that the new emerged coefficient function is one-order continuously derivable and has the same sign with its factor, is added to the known sufficient condition so that a new sufficient condition is obtained.
