摘　　要：统计过程控制(SPC)技术就是选用适宜的统计技术或方法对生产过程实施控制,通过统计分析,科学地区分出生产过程中的随机波动与异常波动,从而实现对生产过程的预防,达到保证产品质量的目的;SPC技术的种类很多,适用于不同的过程控制;选择适宜的SPC技术监控过程质量,是进入SPD(统计过程诊断)和SPA(统计过程调整)必不可少的一步。文章简单介绍统计过程控制(SPC)技术的设计原理和判断准则,重点阐述如何应用SPC技术监控生产质量的过程与方法,并给出应用和分析实例。Statistical process control technology is that choices suitable statistical technology or method to control product process, distinguishes different undulation between conventionality and unconventionality by statistical analyze in order to realize preventing product process and ensure product quality. There ere many SPC technology to be applicable different proccess control To control and watch process by SPC technology is a step indispensably to realize SPD or SPA. This paper simply introduces design principle and judgment rules of statistical process control （SPC） technology, mainly elaborates process and method how to control and watch the process quality by SPC, and the instance of application end analyze was given.
