In this paper we study the structure of panda fibers how to effect the birefringence (beat length) by an infinitesimal element method.

This causes what we call Long QT syndrome, where the length of the heart beat is longer than usual, which greatly increases the risk of arrhythmia.

这可导致所谓的长Q-T综合症。此时心律的长度较正常时延长，可大大增加心律失常的风险。

One of the most important parameters about high birefringence fibers is the beat length. Because of its shortness and periodicity, measuring beat length is a critical one.

高双折射光纤的一个重要参数是拍长，由于拍长很短和周期性变化，如何实现准确测量是十分困难的。

In a thrilling final, James and fellow crew members Andy Hodge, Peter Reed and Steve Williams came from three-quarters of a length down to beat Australia and claim gold.
