推导出了成叠带状光纤在松套管中余长的两个计算公式，此两公式是带状光纤缆结构设计需要用到的基本公式。

We have derived two formulas calculating excess lengths for folded ribbon fiber in loose tube . These formulas are useful for structural design of ribbon fiber cable .

最后我们得出：在松套管的挤出过程中，若选择数量比较大的结晶相，则能够减少套管的后收缩，从而减小光纤的衰减，改善挤出套管的机械强度。

It is very probable that greater quantity of the crystalline phase in tubes , selected during losse tube extruding , could reduce post shrinkage , thus reducing fiber attenuation , and improving mechanical strength of the tubes .
