secondary wall

Fiber elongation and secondary wall thickening stages take a large part of time in the course of cotton fiber development, fiber traits such as length, fineness, and strength are determined by fiber elongation and secondary wall thickening process to a great extent.

纤维伸长和次生加厚占纤维发育过程中绝大部分时间，纤维长度、细度和强度等重要性状在很大程度上由纤维伸长和细胞壁次生加厚进程决定。

Secondary end points included change in L end-systolic and end-diastolic volume indices and wall motion.

次要终点为左室收缩末期和舒张末期容积指数和室壁运动改善.

In a word,α-tubulin has an important action on fiber elongation and secondary wall thickening.

表明α-微管蛋白与纤维发育有关，其变化影响着棉纤维的形态建成，控制着纤维素的沉积方式，即对纤维伸长及次生壁增厚有重要作用。

Light microscopy has also been useful in studies on the secondary wall of the cotton fiber.

光学显微镜还可以用来研究棉纤维的次生层.

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。

The cell wall has undergone secondary thickening , and is often lignified.

细胞壁多发生木质化而次生加厚.
