| 摘 要： | 超声横波周向探伤是超高压水晶釜筒体检验的一个重要手段，为保证扫查到内壁缺陷，其探头入射角在第一临界角附近，由于接近临界角入射，使得声场发生变化，较为复杂，因此给缺陷定位带来困难。通过试验和对声场的定性分析，给出厚壁圆筒形工件周向超声检测缺陷定位的方法。

| Abstract: | 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. |
