在非正弦周期性外力作用下受迫振动的实验结果，并十分清楚地显示了受迫振动的较为完整的图像。
This paper mainly introduces and discusses the experimental results of the forced oscillation excited by a non-sinusoidal periodic driving force.
在顺流向初应力为压应力状态下，系统存在非周期响应，如概周期振动及混沌运动。
When the initial stress is pressure stress, more complicated responses such as almost-periodic solutions and chaos motion are found in the system.
