棉纤维长度受制于水分和热量条件。

The fibre length is influenced by water and heat conditions.

这个大小可以代表第二层壳沉积或棉桃开裂干涸前棉纤维本来的大小。

This large size may represent the initial size of the fiber before secondary-wall deposition or fiber desiccation upon boll opening.

在高温烘烤过程中，棉纤维变成了碳纤维，后者再与硼溶液发生反应生成碳化硼。

The strips were later removed from the solution and heated in an oven. The heat changes the cotton fibers into carbon fibers, which react with the boron solution and produce boron carbide.
