A formula was derived and given to calculate the Shupe effect in the quadrupolar winding including the effects of the midpoint deviation and the fiber diameter. This formula, compared with that considering only the ideal situation, can not only be used to account the thermally induced nonreciprocal phase shift under different midpoint deviations and fiber diameters, but also indicate the effects of the fiber coil's structure when there exist nonideal factors.

本文分析了中点偏差、光纤直径尺寸对四极性绕法中相向传输光对称性的破坏，推导给出了包括中点偏差和光纤直径尺寸影响的四极性绕法热致非互易相移的计算公式，该公式相对于只考虑理想情况的计算公式，不仅能计算不同中点偏差和光纤直径情况下的热致非互易相移，而且揭示了存在非理想因素时，光纤环结构对热致非互易性的影响。

The Constant Modulus Algorithm antenna arrays in the GSM systems are analyzed, CMA arrays can overcome the CCI from the intercells and partially overcome the ISI. The CMA is nonsensitive with the phase shift. The CMA criteria having real part and imaginary part can decreased the reliance of the sequentially temporal equalizer and carrier tracking measures

最后本文研究了CMA阵列天线在GSM移动通信系统中应用的可能性，CMA阵列可以有效地克服共道干扰CCI，部分克服码间干扰ISI，这样一种对相位不敏感的盲算法必须进行后处理，考虑复数的实部和虚部的CMA准则能够减少对后序处理的依赖程度。

By the method, the phase shift of signal was realized with programma. Together with variable gain larger and ilter processing, it made a positive feedback loop to compensate the variation energy loss of micro cantilever.

利用FPGA的可编程数字信号处理功能实现信号的移相，并与可变增益放大、滤波处理模块一起构成正反馈环路。

This phase shift does not occur when n1 〉 n2, or for the refracted light in any cases.

同时指出，折射光的振幅可以大于入射光的振幅，应从能量的角度正确理解这一结果。
