It is obvious that there is an optimum chain length of diblock copolymer for minimizing the mean domain size. 所以，加入等量的嵌段共聚物，存在一个最佳的链长使体系的相区尺寸最小。
This paper presents two type conforming run length control charts with warning limits based on using the number of conforming items between successive nonconforming items. 研究了两种带警戒限的合格品链长控制图，一种是一个链长控制图，另一种是两个链长控制图。
