1. The build of parametric model and parametric estimate of time and fixed quantity tail of block
    定时与定数截尾试验参模的建立与参数估计

2. By synthetically applying the method of cluster analysis and of parametric test and combining with the traditional means of statistical process control, a highly automatic controlling frame suitable for multi-variety and large quantity machine building process was put forward.
    综合运用聚类分析和非参数检验的方法，结合传统的统计过程控制手段，提出了适用于多品种、大批量的高度自动化机械制造过程控制框架。
