| 摘 要： | 本文介绍了一种测量超声波传播时间及幅度的计算机程序。该程序是通过检测接收波的首波起点,实现声时和首波幅度的快速、准确测量。由测试结果,基本能够判断混凝土内部的缺陷。应用该程序在PC—AT机上对混凝土试块上16个测试点声时、首波幅度进行计算,并求出它们的最大值、最小值和平均值,总共花时几秒种。

| Abstract: | A computer program to detect the ultrasound transit time and the first ultrasonic amplitude is introduced in this paper, This program can be speedily and accurately realized to measure the ultrasound time and the first ultrasonic amplitude through detecting the first point of ultrasonic waves. Some flaws of the internal concrete can be fundamentally judged according to the measured results. With this program in computer PC-AT, in all it will only take several seconds to calculate the ultrasonic time, amplitude, and their maximum, minimum and average values at 16 Point of the tested concrete. |
