Switching phenomena with an associated negativeresistance region have been observed in the current-voltage characteristics of lead oxide film sandwiches.
在氧化铅薄膜三层结构的电流——电压特性中发现了具有负电阻区的开关现象。

In effect, a negativeresistance is inserted in the circuit so that its total resistance is zero.
实际上，这就是把负电阻接入电路，使电路的总电阻为零。

The experimental results of analogue circuit show that type-S negativeresistance can be obtained by using two like polarity transistors with various circuit connections.
