1) Nyquist criterion
Nyquist准则
1.
Interpolation function and interpolation method based on Nyquist criterion for PAL signals;
基于Nyquist准则的PAL信号内插函数及插值方式
2) nyquist plot
Nyquist图
1.
Based on the investigation for the relationship between the change rate of the phase angle of a Nyquist plot (CRPA) and the poles of the open-loop system or the closed-loop system, the main regions, in which the frequencies of mechanical oscillation modes lie, are determined and their relevant characteristics with the generators are given using the extreme .
研究了电力系统多变量Nyquist图相角变化率与其反馈模型开环和闭环极点间的关系。

In this article,the authors use C++ and C to compile programs to design a set of computer aided instruction software of drawing methods concerned with frequency response characteristics——the NYQUIST plot and the BODE plot.
采用C+ + 和C混合编程设计了一套有关频率响应特性———NYQUIST图和BODE 图绘图方法的辅助教学软件。
3) Nyquist approach
Nyquist法
4) Nyquist rate
Nyquist率
1.
According to Shannon sampling theorem, however, sampling rate should not be smaller than Nyquist rate, which means that UWB signals have to be sampled at a quite high sampling rate and non-bandlimited signals can not be reconstructed exactly.
根据Shannon采样定理，对信号的采样率不能低于Nyquist率，这就意味着对超宽带信号采样需要很高的采样率，而对于非带限信号更是无法通过采样点准确重建原始信号。

逆Nyquist
1.
A new method based on the inverse Nyquist curve is given to ascertain the stabilizing gain regions of time delay systems using PID controller.
基于逆Nyquist曲线,提出一种时滞系统在PID控制下确定增益稳定范围的方法。

水电站防洪设计几个准则的商榷
2.
Think of Debt Recomposed Standard;
关于债务重组准则的几点思考

分子式：
CAS号：
性质： 系统频率特性是一个复数表示形式，任意频率下的矢量G(jω)，其幅值，∣G(jω)∣，相角为φ(jω)。当频率由零变化到无穷大时，料量G(jω)端点在复平面上连成的一条曲线，由于是复平面上表示，所以称极坐标图。
