您可能已经设计了数据库，以及表
或许大家都设计过数据库,也为表定义过主键,今天我想阐述的是,应该如何正确的设计一个主键,在以往的一些资料中,都没有提及到主键设计的原则.我为此总结了一下:
-you might have designed the database, as well as table-defined primary key, and today I would like to explain is that How should correct the design of a primary key, in the past some of the information. no mention of the primary key design principle. I summarize this for a moment :

本应用例实现NTC热敏电阻器对温度的测量。热敏电阻器把温度的变化转换为电阻阻值的变化，再应用相应的测量电路把阻值的变化转换为电压的变化；SPMC75F2413A内建8路ADC可以把模拟的电压值转换为数字信号，对数值信号进行处理可以得到相应的温度值。-Example realize this application NTC thermistor for temperature measurements. The thermistor temperature is converted to resistance changes, and then the application of the corresponding measuring circuit the resistance change is converted to voltage changes SPMC75F2413A built-in 8-way ADC analog voltage can be converted into digital signal values, Numerical treatment of the signals can be the corresponding temperature value.
