振幅

The waves are sinusoidal in nature, and they have an amplitude and a frequency.

声波实质上是正弦曲线，它有振幅和频率。

The output of the filter was squared in order to store the intensity of the sound rather than just the amplitude.

Furthermore,the stability behavior and accuracy characteristics of the algorithmare proven by a spectral decomposition method.

在前人工作的基础上，提出了一种新的用于解决结构动力分析问题的时间积分方法——Taylor级数方法；建立了求解线性问题和非线性项可以表示为多元多项式形式的非线性问题的Taylor级数方法的理论，并给出递归求解通式；阐述了该方法的程序实施过程，给出了计算流程图，并在非线性有限元分析平台NFAP中嵌入了Taylor级数方法的计算模块；利用谱分解的方法分析了该方法的稳定性和精度特性，以封闭的解析形式给出了描述积分法特性的周期延长率和振幅衰减率的表达式；通过对该方法的理论分析和特性研究，阐述了该方法的可行性和高效性。

For this purpose, the time course of the electromyogram has to be analysed, in order to detect typical fatigue-induced changes such as an increase in EMG amplitude or a shift in the spectral distribution towards lower frequencies.

对於这个目的，肌电讯号的时间轴是必须被分析的，为了检测出典型引起疲劳的改变，例如增加EMG的振幅或是转换频谱分析至较低的频率。

We measure the spectral ratio of E01 to E02 in a window which includes direct S waves.

首先，我们将E01和E02的记录分别截取一段包含直接S波的波线，并求其傅氏振幅谱，然后再求E01对E02之频谱比。

It also has a built-in amplitude envelope editor, a customizable spectrogram mode and a frequency analysis window for audio analysis applications.

它也有一个内置的振幅包络编辑器，可定制的频谱模式和音频分析应用的频率分析窗口。

In this paper the complex scattering amplitude functions of a small metamaterial spheroid particle is derived.

This research uses high sensitive piezoelectric sensor for developing a sensitive sphygmograph to detect anthropic pulse and to determine parameters to diagnose physiology of human. From spectrum of pulse, the analysis processes are to determine the high pass frequency used in the analysis, uses the IIR Buttorworth filter to remove the noise, to calculate the Hermite curve for filtering the oscillation parts caused by breathe, then to calculate the parameters in strength, time and angle domains from the processed signal to study their correlation with the physiology of the studied experimenters and compared the results with the machine from the market.

The historic display mode for seismic records graphs amplitude as a function of time for each geophone group output, giving wiggle trace or squiggle or conventional display.

以前的地震记录图形显示方式是把每一组检波器的输出振幅作为时间的函数，给出波形道或波形曲线或常规显示。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
