稍微补充点。Process变量是什么呢?不像温度,电压这些物理量,process不是一个可以计量的量。它是为了达到数字化特性描述和验证的目的slow, typical或fast process中的一个。
What is the Process Variable?
Unlike temperate and voltage which are physical quantities, the process is not a quantifiable quantity. It is likely to be one of slow, typical or fast processes for the purposes of digital characterization and verificaiton. |
