摘 要
介绍了纵波检测用对比试块透声特性的控制、测试方法以及试块透声性测试中原材料检测、平底孔的检测、成品试块检测的验收方法,并重点介绍了水浸检测回波幅值拟合曲线的两种制作方法。
Abstract
This paper introduces the control and testing method of the sound transmission characteristic of the contrast test block used for longitudinal wave testing, the testing method of the raw material, the testing of the flat bottom hole and the testing and acceptance of the finished test block in the sound transmission testing of the test block, two methods of making fitting curve of flood detection echo amplitude are also introduced in detail.
