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，存在一個(gè)最佳的鏈長(zhǎng)使體系的相區(qū)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. 研究了兩種帶警戒限的合格品鏈長(zhǎng)控制圖，一種是一個(gè)鏈長(zhǎng)控制圖，另一種是兩個(gè)鏈長(zhǎng)控制圖。
