电磁波应用于长导体断点无损检测的研究

Research on Applying Electromagnetic Wave to Long-conductor′s Breakpoint NDT

在对电磁波在传输线中的传播理论进行分析的基础上,根据电磁波在均匀传输线中传播的特点,提出了对长导体内部断点进行精确定位的方法———脉冲反射法.基于脉冲反射法原理设计了一套发射接受电路装置,可以用该装置检测长导体的内部断点或对长导体进行测距.

On the basis of the analysis of the disseminating theory about electromagnetic wave in the dissemination line the feature of the dissemination, raised the method of reflected pulse, a method to accurately locate the breakpoint in the long-conductor.The launching-receiving circuit-device which can use for the testing of breakpoint location in long-conductor or distance of the long-conductor is desighed.
