摘　　要：为进一步研究计算机射线照相(CR)检测技术与常规射线检测(RT)技术的差异,以包含气孔、裂纹、未焊透等典型缺陷的构件为对象,分析了其CR检测与常规射线检测的检测结果,一定程度上验证了二者的等价性问题,为后续实际产品的检测应用奠定了基础。In order to further study the differences between computed radiography(CR) testing technique and conventional radiography testing(RT) technique, components with typical defects such as pores, cracks and incomplete penetration were taken as the research object, and the results between CR testing and conventional RT were analyzed. To a certain extent, the equivalence of the two is verified, which lays a foundation for the subsequent application of actual product testing.
