摘　　要：应用混沌理论研究热激发非线性振子的振荡性质，发现对一定的非线性温度场，当参量在一定范围内取值时，阵发混沌脉动会自发出现在由振子所描述的绝热方程中。根据参数Ｑ与Ｒ的不同相对值，可以预测将发生什么样的振荡性质，因而此结果可用来估计脉动变星内部的脉动特性。Basing on the chaotic theory,the oscillating properties of a thermally excited non-lin-ear oscillator has been investigated.The result shows that the pulsation of intermittent chaos canoccur spontaneously in the adiabatic equation described by the oscillator within a certain paramet-ric region when the specific non-linear temperature profile is satisfied.According to the differentrelative values of the parameters R and Q,one may predict what oscillating properties will be hap-pened.Hence,one may use this method to estimate the pulsation properties inside the pulsationvariable star.
