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!)

定义法计算计算Lorenz系统lyapunov指数，结果比较精确！ 可以改为任意3维动力系统的lyapunov指数的计算程序！(Define of the method to calculate the Lorenz system lyapunov index, accurate results! Can be changed to any 3-dimensional dynamical systems lyapunov index calculation program!)

MELP是一种先进的语音编码算法，希望对大家有用(MELP is an advanced audio coding algorithm, we want to be useful)

Offset quadrature phase-shift keying (OQPSK) is a variant of phase-shift keying modulation using 4 different values of the phase to transmit. It is sometimes called Staggered quadrature phase-shift keying (SQPSK).
