Sinking数字输出通过三极管来控制连接线上的电平为高电平(+ V)或是低电平(0 V)。
The sinking digital output controls the line by using a transistor to leave the line high (at + v) or to ground the line to 0 v.
Sourcing数字输出通过三极管控制连接线上的高低电平。
The digital output controls the line by using a transistor to leave the line at 0 V or to raise the line to +V.
准确、通俗地传递关于三极管输出特性曲线的科学含义，方便教学，是本文的初衷。
Accurately express the scientific meaning of the saturated area of the triode transistor characteristic curve in teaching is the original purpose of this paper.
