摘要
该文研究系统ｘ＋ＲＦ＇（ｘ）ｘ＋１ＬＦ（ｘ）＝Ａｅ（ｔ）Ｆ（ｘ）＝∑ｎｉ＝０ａ２ｉ＋１ｘ２ｉ＋１出现的概周期振荡现象，结合运用Ｌｉａｐｕｎａｖ函数，获得了系统产生概周期振荡的先兆性条件，为避免系统产生概周期振荡提供了参考数据。
This paper deals with the x··+RF'(x)
x·+1LF(x)=Ae(t) F(x)=∑ni
=0a2i+1x2i+1 in which almost periodic oscillation may occur.B
y using Liapunov function,the ominous condition of almost periodic oscillation i
s obtained,this work provides the reference data to distinguish almost periodic
oscillation.
