平坦地

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。

First, a large class of ideal Einstein and conformally flat immersions are proved to be totally geodesic, which generalizes a theorem of Dillen on the simplest ideal immersion.

首先证明了实空间形式中一大类理想的爱因斯坦和共形平坦浸入均为全测地浸入，所得结果大大推广了Dillen等人关于欧氏空间中最简单的理想浸入定理。

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。

Now, typically it's in a flat file.

现在，典型地它是在一个平坦的文件中。

In addition to the territory of the Central Valley Guangtong flat alluvial terrace, the other areas covered hills, ravines China.

境内除中部广通河谷冲积阶地地势平坦外，其余地区则丘陵密布，沟壑纵横。

During the night the train left the mountains behind, and passed Nassik, and the next day proceeded over the flat, well-cultivated country of the khandeish, with its straggling villages, above which rose the minarets of the pagodas

夜间，火车穿越高止山脉，过了纳西克，第二天是10月21号，火车驶过堪得土地区一片比较平坦的土地。在那精耕过的田野上，零星地点缀着一些小镇。在这些小镇的上空，见不到欧式礼拜堂的钟楼，却看到一些寺院的尖塔。

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！

For those who are determined to travel, they will go forward happily all the way in plains, and they will become more enjoyable, full of humor and wit, while confronted with cragged roads, thinking that they would feel the beauty and interest of the adventure better.

志于旅途的人，走到平坦的地方，因是高高兴兴地向前走，走到崎岖的境界，愈是奇趣横生，觉得在此奇绝壮绝的境界，愈能感到一种冒险的美趣。

When those who have devoted themselves to travelling come to a flat place, they will march on happily; when they come to a cragged place, they might think it very interesting and enjoy trying and doing it.

志于旅途的人，走到平坦的地方，因是高高兴兴地向前走，走到崎岖的境界，愈是奇趣横生，觉得在此奇绝壮绝的境界，愈能感到一种冒险的美趣。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
