本文介绍根据超声波声场理论对有关基本公式进行变换后建立的数学模型,并以此按JB 1152-81标准编制的程序,可用以计算机绘制距离-波幅曲线,计算当量直径的大小和绘制缺陷的位置图。
This article describes the ultrasonic sound field theory based on the transformation of the basic formula of the mathematical model established, and then according to JB 1152-81 standard program can be used to draw a computer distance-amplitude curve, calculate the equivalent diameter and the location of the location of defects Figure
