增加相噪的程序，可以把测量结果转化为相为噪声，使用非常方便。-The program to add phase noise, the measurement results can be translated into phase noise, very convenient to use.

展开相位是物体表面三维形貌测量中一项关键技术，为了避免相位展开过程中的误差传播效应，Saldner和Huntlye等提出了时间相位展开方法。用matlab模拟了时间相位展开的方法-Expand the phase surface 3D topography measurement of a key technology in order to avoid the phase unwrapping process of error propagation effects, Saldner and

Lamb波的频散曲线是进行超声Lamb波无损检测的重要依据。本程序对Rayleigh2Lamb方程进行了分析，给出了无限大板中Lamb波频散曲线的数值计算方法，通过Matlab软件对求解过程进行编程，绘制出Lamb波在铝板中传播的相速度和群速度曲线，并通过试验进行了验证对推广应用Lamb波进行无损检测具有实际意义。(The dispersion curve of Lamb wave is an important basis for non-destructive testing of ultr
