摘要
介绍了超声波衍射时差法(time offlight dif fraction,TOFD)检测技术的基本原理。为此,基于应用实践,对检测灵敏度的调节等主要问题进行了探讨,为TOFD检测技术的应用推广提供参考。
The ultrasonic diffraction-time detection technology to the basic tenets of this, based on the application of the detection sensitivity of the regulation, and major issues were discussed, TOFD detection technology to provide a wider application of reference.
