摘要
介绍一种利用LC振荡电路的磁回路探测材料表面和内部伤痕的方法.实验证明,该方法能应用于高压容器的深层探伤,且效果很好.
The property of circular magnetic loop of coil-condenser circuit is studied, and a serials of exploring experiment is carried out to detection of defects for ferromagnetic materials of high pressure vessel. The results show that our instrument is suitable for inspecting the defect of inner of ferromagnetic materials.
