不平坦

Slither can mean to slip and slide, as on an uneven surface, often with friction and noise

Slither 可以指在不平坦的表面上的滑行或滑动，通常产生摩擦和噪音

These shoes tend to be more weather and water resistant and are slightly stiffer for better stability on uneven terrain.

这些鞋更趋于天气和耐水性和略带严厉的，为更好地稳定了不平坦的地形。

Beginning with wave equation, the paper has deduced the propagation of gauss pulses in single mode fiber and fiber grating transmission compensation. The characteristics of cascaded phase-shift gratings are discussed by numerical simulations of coupled-mode theory and T-matrix method. The experimental works and measurement results are shown in this paper. On the other hand, we have introduced the basic theory of EDFA and figured out the characteristics for EDFA at different conditions by numerical simulation. Some experimental results for EDFA are also presented here. In this article, you can find the influence on Optical Fiber Amplifier by Gain Tilt, especially, the negative effect on CSO in CATV transmission system.

论文首先从波动方程入手，对高斯脉冲在单模光纤中的传播演化及光纤光栅透射补偿进行了详细的研究；较系统地介绍了光纤光栅的耦合模理论，并将传输矩阵计算法用于计算级连相移光纤光栅的光学特性；重点介绍了作者在光纤光栅刻制及特性测量方面所做的一些实验研究工作；较系统介绍了EDFA的基本理论，计算出各种条件下EDFA的光学特性，并进行了一些实验研究；综合分析光纤放大器对光纤传输系统的影响，特别分析了光纤放大器增益不平坦对光纤CATV系统中CSO恶化的原因及其解决方法，并研究了光纤布拉格光栅在稳定980nm泵浦源输出功率和输出波长方面的应用；结合一个基于光纤光栅和光纤放大器的光纤用户接入网方案，对光纤用户接入网的若干问题进行了理论与初步的实验研究。

Though the road before us is still uneven, and the scenery is not all turquoise water and green hills, what of that? Life's meaning lies in walking firmly ahead, in the courage to not turn back after a hundred setbacks, in every step of our advance toward our own ideals.

尽管前路仍不平坦，风景也并非都是绿水青山，但又有什么呢，生命的意义，在於脚踏实地的行进，在於百折不回的勇气，在於我们朝着自己的理想向前走的每一步。

That's a lot of time to get sidetracked and end up down an unproductive, frustrating and rocky road.

这是一个很长的时间去得到侧面，并最终降低了非生产性的，挫折和不平坦的道路。

They read the nine thousandth tale about Zebulon and Sophronia, and how they loved as none had ever loved before, and neither did the course of their true love run smooth —— at any rate, how it did run and stumble, and get up again and go on!

他们读了九千个关于西布伦和赛福隆尼亚的故事，他们如何相爱，从没有人这样地相爱过，而且他们的恋爱经过也不平坦，——总之是，他们如何爱，如何栽跟斗，如何再爬起来，如何再相爱！
