摘　　要：NB/T 47013-2015标准中的CSK-ⅡA-2、3试块引入了一个90°尖角,成功地解决了在纵波检测时,各孔相互遮挡而无法实现不同距离反射体正常回波这一问题,但在解决问题的同时,并没有及时地给出各个反射体距离的尺寸与算法。本文从孔距的算法开始,讨论了原设计中参数的不足,并提供了新的参数,使计算公式简单明了,计算结果均为整数,避免了无理数的使用,同时给出了两个试块在纵波检测时各个孔与检测面的组合使用大表。CSK-ⅡA-2/3 blocks in NB/T 47013-2015 standard introduce a sharp angle,which successfully solve the problem that the holes overlap each other and can not realize long-distance reflector in Pwave inspection,but the distance of each long transverse hole to any plane is not provide,and the algorithm of the distance is not provide too.In this article,the shortcomings of the parameters in the original design are discussed,and new parameters are provided,which make the calculation formula simple and easy.The calculation results are all integers and convenient to use.
