撑篙竹的三年生纤维长度的变化,从30条原竹选出4条试竿的第2至第24节间的中央位置,在离析材料的制片中,分别以投影方法量度外部纤维、中部纤维和内部纤维,共计13800条纤维的结果,可以概括如次:内部和中部两者的平均纤维长度,系随节间顺序的上升而波动地增加,当长度达相当程度时,则随节间顺序的上升而波动地减少。然而,外部纤维长度是随节间順序的上升而波动地减少的。节间长度的增加和下降,它类似内部和中部的纤维长度,系随节间顺序的上升而发生变化。
The length of the three-year-old bamboo fiber was changed. The central positions of the two test rods from the 30 bamboo strips were selected. The outer fibers were measured by the projection method in the production of the segregation material, The results for a total of 13,800 fibers from the middle and inner fibers can be summarized as follows: The average fiber length for both the inner and middle parts fluctuates as the internode sequence increases, and when the length reaches a certain degree, Fluctuation decreases with increasing sequence. However, the external fiber length fluctuates diminishing with increasing internode sequence. Internode length increases and decreases, which is similar to the length of the fiber inside and in the middle, as the internode sequence changes.
