横截面

It is found that the fiber of phloem of broussonetia is irregular elliptoid at cross section.

现皮纤维的横截面是带有中腔不规则的椭圆形结，且呈束纤维分布。

It was found that fibers of circular cross section produce greater cohesion in webs and slivers than do trilobal fibers.

圆形横截面纤维在棉网和棉条中，三叶形横截面纤维能产生较大的粘着作用。

The cross section morphology and skin-core structure of PAN fiber in wet-spinning are analyzed by the means of electron probe microanalyser (EPMA) and scanning electron microscope (SEM).

结果表凝固浴温度会影响初生纤维的横截面形貌与芯部结。
