I barely got off a shocked "Hello" when the raspy voice said: "I saw your show on the History Channel, and I have a business proposition for you."
我还没在惊吓中回他一句:“你好。”这个急躁的声音又说:“我看了你在历史频道的节目,我有一个业务要给你。”
The design incorporates a channel thin enough to become entirely devoid of carriers (ie, free electrons or holes) when switched off, thus acting as a valve, yet full of them when switched on.
这一设计包含了一条足够细的隧道,当它关闭时,里面完全没有载流子(电子或空穴),当它打开时,里面便充满了载流子,起到了阀门的作用。
