峰值振幅 peak amplitude
- 这种脉冲变宽,其峰值振幅时间随相继气帘数目的增加呈直线性延迟。
This pulse broadens and its peak amplitude is delayed linearly as the number of successive air curtains is increased. - 本文提出对于轻阻尼多自由度系统,可以自然地把单自由度系统峰值振幅转速的概念推广为共振转速区的概念。
In this article, we propose the concept of a region of resonant speed to be applied to vibration of lightly damped multi-degree-of-freedom systems. - 第一个空气流使峰值振幅大大降低,以后就保持在无气帘时振幅的0.1到0.2倍。
The peak amplitude is decreased substantially by the first air stream and thereafter remains between 0.1 and 0.2 of the amplitude without air curtains.
