随着正弦波频率增加岩石的滞回圈频散效应增强，饱和液体加强了这种频散作用。
When the frequencies of the sine waves increase, the frequency dispersion of the hysteresis loops of the rocks is strengthened. This effect is also intensified with the saturation fluids.
自适应IIR陷波器在许多不同的信号处理场合，尤其在估计淹没在噪声中的正弦波频率方面得到广泛应用。
The Adaptive IIR notch filter has been widely used in many signal processing applications, especially in the estimation of the sinusoid component with unknown frequency buried in noise.
现实中的信号由各种频率的正弦波组成，因此，在有限的波长数后，它们会干涉相消，你就得到一个有限宽度和有限延续的信号。
Realistic signals are made by summing sine waves of lots of frequencies, so that after some finite number of wavelengths they interfere destructively and you get a signal of finite width and duration.
