摘要
本文详细阐述了超声波透射法的工作原理,并借助工程实例,从声时、声幅、声速、PSD、波形几个方面比较了其对缺陷的敏感程度,以供同行参考。
This paper intcoduces the work principle of ultrasonic penetration,and based on the practice,it compares the defect sensitivety in acoustic time,acoustic amplitude,acoustic speed,PSD and wave and it is hoped to be a references for other similar engineering.
