随着电子计算机技术的发展,它的应用也已开始涉足无损检测这一领域。近几年来,欧美、日本等一些国家在这方面发展较快,先后研制成功了数字和电子计算机图象处理的自动化超声波检测系统,计算机的x光、γ射线照相自动检测系统以及应用微型计算机的表面缺 With the development of computer technology, its application has also begun to get involved in the field of nondestructive testing. In recent years, some countries such as Europe, the United States and Japan have developed rapidly in this regard. They have successively developed automated ultrasonic testing systems for digital and electronic computer image processing, x-ray and γ-ray automatic detection systems for computers, and microcomputer-based The surface is missing
