小径管射线检测时椭圆成像与垂直透照方法的对比

摘要

文章探讨了小径管射线检测时椭圆成像与垂直透照的对比及小径管透照布置对裂纹检出的影响，对于正确执行检测标准和提高裂纹检出率有一定的借鉴意义。%This paper discussed the comparison hetween elliptic imaging and vertical transmit of small diameter pipe, and the impact of radiographic arrangement on detecting the crack, and it had some reference meaning to execute the detecting standard correctly and improve the detection efficiency of crack.
