从而推得多叶应力区扭转光纤中的超本地模，由超本地模的相位常数来确定该光纤的双折射。

Then, super-local modes in multi-lobe stress region spun fibers can be obtained by using mode transform. Finally, the fiber birefringence is decided from the phase constants of super-local modes.

本文还证实了线性超应力模型可以予测实验条件下等应变区的存在，给出了铝和铜的速率灵敏系数K的建议值，讨论了铝的K值的普适性等问题。

The numerical values of the rate-sensitivity parameters K for aluminum and copper are proposed. The essence of general applicability of parameter K is considered for aluminum.
