介绍了共振隧穿二极管（RTD）中电荷积累效应，利用顺序隧穿模型分析了RTD中有电荷积累时器件各部分电压的再分布；

The electric charge accumulation effect in RTD was introduced. The electrical voltage redistribution along the device as charge accumulated was analysed by sequential tunneling model.

结果表明，外加磁场破坏量子点能级的自旋简并，使得电荷流和自旋流的共振峰劈裂开，得不到纯自旋流。

Numerical results show that the resonance peaks of spin current split and the pure spin current disappears due to the magnetic field destroying the degeneration of electron spin in quantum dot.

因此我们会专门讲一讲，如何来画路易斯结构，然后再讨论形式电荷与共振论，它们也属于路易斯结构的范畴。

So we'll talk specifically about drawing Lewis structures and then about formal charge and resonance, which are within Lewis structures.
