摘要

从人体声发射技术与医学检测的特点出发

将人体骨科疾病的诊断和人体声发射结合起来

提出了具体的研究问题和解决手段。通过BL—420生物机能实验系统采集人体骨骼中的声发射信号

对该声发射信号利用互相关法计算时差

从而实现声源定位。

Abstract

According to characteristics of acoustic emission and medical test

and combining the orthopedics diagnosis with acoustic emission

and concrete practical problems and solutions are put forth.Acoustic emission signal in human skeleton can be attained through BL—420 organic experiment system

and time difference can be calculated by the acoustic emission signal in applying cross-correlation analysis

so the location of acoustic source can be implemented.
