Study of Sound Field Characteristic and Defect Position while Inspecting the Ultra-high Pressure Artificial Crystal Reactor by Transverse Wave

It is an important inspection method to inspect the ultra-high pressure artificial crystal reactor by transverse wave. In order to checking the defect in the inner face, the angel of the probe is closed to the first critical angle , and the sound field characteristic is more complex than others. It is difficult to determine the defect position. Through experimentation and analyzing the sound field characteristic, a way to solve the problem was given.
