pcw怎么记

By way of complex extraction with PCW-6 extractant to recover glycolic acid from the wastewater, the paper discussed different effects of each factor ( such as acidity, extractant concentration, oil-water ratio, temperature, and equilibrium time) to the extracting efficiency.

以PCW-6为萃取剂，采用络合萃取法回收废水中的羟基乙酸，探讨了各因素（酸度、络合剂浓度、油水比、温度、萃取平衡时间）对羟基乙酸萃取率的影响；

A series of complex regulations in PCW stage finally affect fiber cell intensity and length. Cellulose synthesis and SCW deposition in later phase determine cotton fiber yield and quality at last.

初生壁阶段一系列复杂的调控影响棉纤维细胞密度和长度，纤维素合成与次生壁沉积最终影响棉纤维的产量和品质。

Cotton fiber cell wall is usually divided into two categories: the primary cell wall ( PCW) and the secondary cell wall ( SCW) during cotton fiber development.

在棉纤维发育过程中，纤维细胞壁发育通常可分为初生壁和次生壁两个阶段。
