文章叙述了CT探伤原理,介绍了CT在箭药无损检测技术中的应用情况,用资料图片证明它具有密度分辨能力,可区别药柱内部各部位的密度差,它采用分层扫描、重建技术,使得探伤精度大大提高,它采用了电子计算机技术,不但可贮存探伤数据,还可进行数据处理,再现疵病的大小和空间立体结构。这些独特的探伤优点有力地促进了科研、指导了生产。 This paper describes the principle of CT flaw detection, introduces the application of CT in the nondestructive testing of arrowheads, and uses the data to prove that it has the capability of density resolution, which can distinguish the density difference of various parts inside the drug column. It uses the technique of layered scanning and reconstruction , Making the detection accuracy greatly improved, which uses computer technology, not only can store the test data, but also for data processing, the size of defects and reproduction of three-dimensional spatial structure. These unique flaw detection advantages have effectively promoted the scientific research and guided the production.
