显而易见的

Then, making use of the concept of eigenstate of polarization , the Jone's matrices of the coupler and the fiber are discussed in order to study the polarization state of the light in the resonator ring. The situation can be distributed into three kinds, two ESOPs are orthogonal, not orthogonal and only one ESOP exits, and each coincides to the special quality of the components in the ring.

其次借助偏振特征状态概念对偏振环中的光束偏振状态进行研究，从耦合器和光纤的琼斯矩阵着手，推导出表达偏振特性的公式，再将偏振情况分为三类，分别是两ESOP正交、不正交和只有一个ESOP，每一种情况都与组成光纤环的元件实际的性能相符。

Catch a reflection of yourself in this one every morning and you are guaranteed a super day.
