关于麦克风阵列信号处理，根据声波传达理论，利用多个麦克风收集的信号可以将某一方向传来的声音增强或抑制，通过改变权值来改变某一方向的信号的接收强弱(About microphone array signal processing , according to the theory of sound waves to communicate using signals multiple microphones to collect a certain direction came the sound can be enhanced or inhibited by changing the weights to change the receive signal strength in a certain direction )

说明：  本文利用数值仿真的方法分析了转子系统穿越临界 转速的瞬态响应，研究了转子起动加速度、支承刚度以 及阻尼对转子穿越临界转速振幅的影响规律，得到如下(In this paper, the method of numerical simulation is used to analyze the rotor system crossing the critical state The transient response of the rotor speed, the starting acceleration and the support stiffness are studied And the influence of damping on the amplitude of rotor through critical speed is obtained as follows)

This function is a very simple application of FFT2 for an image to simulate the effect of bandpass filter with two cut off frequencies. One can easily modify the programme to do the processes for different images, and even implement highpass and lowpass filter
