摘　　要：从校准的定义出发,引申出了仪器仪表自校准的概念,并对自校准实现的基本原理和过程进行了分析,提出了自校准设计过程中几个关键点,以及这些关键点对自校准的影响。同时,文章通过对电测仪表和电流源、电压源仪器自校准实现方法的分析,进行一步阐述了自校准仪器仪表的"自校准"机理。最后指出,随着SI单位基准的物理常数化,电测仪表自建参考基准将成为可能,从而真正实现仪器仪表的自动精确校准。The article introduces the method of Self-Calibration from discussing the definition of calibration first,analyzing the key points in the process of self-calibration.Then,the article elaborates the mechanism of the selfcalibration through two examples: self-calibration of measuring instrument and self-calibration of voltage source.At last the article points out that the precise self-calibration will come true with the progress of the design of precise integrated reference measuring standards awing to the effort of making the measuring standard of SI unit to a constant.
