摘　　要：制造过程中异常原因引起的样本组内波动会导致控制图监控能力的下降,以制造过程中样本波动为研究对象,采用统计模型将样本波动分离,分析出样本组内波动,为控制图有效构造及提高监控能力奠定基础,并给出了具体的实现过程;最后,通过应用实例表明这种方法对于样本组内波动的分析是行之有效的。In manufacturing process, abnormal causes variations within sample group can increase the line of control chart, and make it＇ s has a lower detection capability. According to this problem, using a statistical model to separate the sample variations can analyze variations within sample effectively, and make a foundation for the construction of control chart and the increasing for its detection capacity. Finally, taking a project as an example, it has been proved that adopting this method to detect the variations within sample in manufacturing is practical and effective.
