超声波检测混凝土，正演分析，通过一正弦入射波检测混凝土内部是否发生破坏或损伤(Ultrasonic inspection of concrete, forward analysis, incident detection by a sinusoidal internal concrete damage or injury has occurred)

最速下降法就是梯度下降法,可以用于求解最小二乘问题(线性和非线性都可以)。可以说是求解机器算法的最古老、最经典的模型，另一种常用的方法是最小二乘法。(The steepest descent method is the gradient descent method, which can be used to solve the least squares problem (both linear and non-linear). It can be said that it is the oldest and most classical model for solving machine algorithm. Another commonly used method is the least square method.)
