1. The separability of asymptotically strongly periodic function space and asymptotically periodic sequence space are also discussed. 研究了渐近强周期函数空间、渐近周期序列空间的可分性质。
2. Exciting results are obtained when this control algorithm is applied to the structural vibration reduction with periodic and pseudo-periodic signals. 此种方法，对于周期扰力以及拟周期扰力激起的结构振动响应都有很好的控制效果。
3. The method can correctly testify the distorted points in single periodic signal. Thus it is applicable in the periodic signal which can not be eliminated by averaging method. 此方法可在单个周期性信号中确定畸点，适用于无法用多次平均法消除畸点的周期性信号。
4. It proves by the generalized degree theory that the equation has at least one N-periodic solution if the corresponding homogeneous equation has only a trivial N-periodic solution. 利用广义度理论证明了方程在对应齐次线性方程只有平凡的N周期解的情况下至少存在一个N周期解。
5. Although manufacturer people had become mature in periodic oscillation, but in the future the periodic oscillation of the market still will long-standing, just amplitude will be smaller and smaller. 当然厂商们已经在周期振荡中变得成熟，但未来市场的周期性振荡仍旧将长期存在，只是振幅会越来越小。
