1·In this paper, we discussed the method on surveying the interrupted point and length of concentric cable by alternating bridge.

介绍了利用交流电桥测量同轴电缆断点和长度的方法。

2·In this case, which seems to violate the no shield current rule for receiver circuits, the concentric cable is not used to shield the center lead; instead, the geometrv produces cancellation.

这个例子看起来违背了上文“屏蔽体一定不能有电流”的准则，但是这里屏蔽电缆并非用来屏蔽芯线，而是通过这种特殊接法抵消干扰。
