检测技术是一门既古老又处于迅速发展阶段的学科,是任何科研工作、生产实践必不可少的手段。近些年发展起来的无损检测技术则是一项新颖的综合性测试技术。所谓无损检测,就是在不损伤被检物体的前提下,检查物体内在或表面缺陷,或测定其某些物理量、性能、组织状态等的材料试验方法。最初这种方法仅被用来检查材料、机械零部件和结构件的缺陷。在生命科学、生态平衡、环境保护已逐渐成为重要研究对象的现
Detection technology is an old and rapid development of the discipline, is an indispensable means of any scientific research, production practice. In recent years, the development of non-destructive testing technology is a novel comprehensive testing technology. The so-called non-destructive testing, that is, without damaging the test object under the premise of checking the internal or surface defects, or determine some of its physical properties, performance, tissue state material testing methods. Initially this method was only used to inspect defects in materials, mechanical components and structural parts. In the life sciences, ecological balance and environmental protection have gradually become important research objects now
