用于周期复振荡研究的微分方程解的一个结果

A RESULT OF DIFFERENTIAL EQUATIONS USED FOR THE RESEARCHES OF COMPLEX OSCILLATION

提出了“组合优势条件” ,并用其发展了S .Bank和J.Langley于 1992年证明了的用于周期复振荡研究的一个重要结果 。

S. Bank and J.Langley proved an important result which is used for the researches of periodic complex oscillation in 1992, but sometimes its dominant condition is not applicable. In this paper, the ‘combined dominant condition’ is put forward which developed Bank's and Langley's result and extended its applicability greatly.
