第1条 应该是比较贴切的，同样也是MOS管里漏极的概念；

不知道是汉语语义的漫变还是理工科人文科都差劲，这个词还是别扭。

简单理解，Sink 漏的比较快，“面”漏； Drain是”点“漏；

但是总比什么”灌“要好被人理解；

Sink

Drain

A floor sink is typically a square or rectangular receptacle that sits below the floor level, designed to receive indirect waste from fixtures such as sinks and dishwashers. In contrast, a floor drain is a circular drain situated directly on the floor, primarily intended to remove standing water and prevent flooding.
地板水槽通常是位于地板下方的方形或矩形容器，旨在接收来自水槽和洗碗机等固定装置的间接废物。相比之下，地漏是直接位于地板上的圆形排水管，主要用于清除积水和防止洪水泛滥。

2 Source

1. The source of something is the person, place, or thing which you get it from.
2. In business, if a person or firm sources a product or a raw material, they find someone who will supply it.
3. A source is a person or book that provides information for a news story or for a piece of research.
4. The source of a difficulty is its cause.
5. The source of a river or stream is the place where it begins.

第5条 应该是比较贴切的，同样也是MOS管里源极的概念；

被人通俗的介绍为“拉”，但这样搞不清是往哪个方向”拉“？？汉语的“拉”取决于你自己的相对位置。

还是“源”这个词高一点，起始的位置，或者直接理解为“输出”；
