将断层剖面划分为一组网格，并以固定的事件数或固定的扫描半径，计算每个网格点处的b值。然后用色彩表示断层面上b值的分布情况，从而反应断层的应力积累情况，便于地震学家分析该断层是否存在发震的可能(This subroutine creates a grid with spacing dx,dy (in degreees). The size will be selected interactively or grids the entire cross section. The b-value in each volume is computed around a grid point containing ni earthquakes or in between a certain radius. The standard deviation is calcualted either with the max. likelihood or by bootstrapping, when that box is checked. If not, both options can be assigned by the additional run assignment. Standard deviation of b-value in non-bootstrapping case is calculated from Aki-formula!)

基本的数字信号处理matlab源代码，包括IIRdemo.m，nyquist_aliasaudiodemo.m，sinfreqdemo.m等(Basic digital signal processing matlab source code, including IIRdemo.m, nyquist_aliasaudiodemo.m, sinfreqdemo.m etc.)

锁相环就是锁定相位的环路。学过自动控制原理的人都知道，这是一种典型的反馈控制电路，利用外部输入的参考信号控制环路内部振荡信号的频率和相位，实现输出信号频率对输入信号频率的自动跟踪，一般用于闭环跟踪电路。(Locked loop (phase), as the name implies, is the lock phase of the loop. Principle of automatic control of the people know, this is a typical feedback control circuit, the external input reference signal control the frequency and the phase of the oscillation signal inside the loop, the frequency of the output signal of the input signal frequency automatic tracking, generally used for closed-loop tracking circuit. )
