This article proposes an optimization design parameters of CUSUM control chart based on quality fraction defective. 提出以质量不合格率这一质量指标为目的,优化CUSUM控制图的参数,建立了优化设计理论模型,提出了优化分析的流程,进行了实例分析和验证。
A quality-oriented fraction defective optimized design on CUSUM chart 面向质量不合格率的CUSUM控制图参数优化设计
When the mole fraction of ursolic acid is small, the morphology of monolayer appears defective film. With the increase of the fraction of ursolic acid on the monolayer, obviously aggregation can be found. 在熊果酸的摩尔分数较小时,单分子层会出现有缺陷的膜的形貌,随着熊果酸含量的增加,单分子层上出现更明显的聚集现象。
