摘　　要：射线检测技术几乎可用于所有材料的检测,可直观地显示缺陷的特点,便于定性、定量分析缺陷,但很难发现垂直射线方向的薄层缺陷。采用平移法测量缺陷深度能够准确地测量出缺陷在工件中的深度,适合工业射线对缺陷深度进行定位,特别适用于野外等施工条件较差的工作环境。平移法测量缺陷深度基本达到了节约资源、节约时间、误差较小的目的。Radiography can be used for nearly all materials testing,visualize the characteristics of defects,flaws in qualitative and quantitative analysis,but difficult to find vertical-Ray thin-layer defects.Translation method for measuring defect depth can be accurately measured the depth of the defect in the work piece,particularly suitable for field construction conditions such as poor work environment.Translation method for measuring defect depth reached the purpose of saving resources and time saving and less error.
