A time always comes at which the moral principles originally adopted have been carried out to all their legitimate consequences, and then the system founded on them becomes as rigid, as unexpansive, and as liable to fall behind moral progress as the sternest code of rules avowedly legal.

这样一个时期是必然会到来的，就是原来采用的道德原则已经发挥出了所有的合法的结果，于是，建筑在这些道德原则上面的制度，就会像最严峻的法律法典那样地生硬、那样地没有伸缩、那样地不得不落后于道德的进步。

The truth was, that the little Puritans, being of the most intolerant brood that ever lived, had a vague idea of something outlandish, unearthly, or at variance with ordinary fashions, in the mother child; therefore scorned them in their hearts, not unfrequently reviled them with their tongues.

事实上，这伙小清教徒们是世上最不容人的，他们早就在这对母女身上模模糊糊地看出点名堂，觉得她们不象是人世间的人，古里古怪地与众不同；于是便从心里蔑视她们，嘴里时常不干不净地诅咒她们。

Quickly he unloaded his burden, wincing as the man thudded ungently to the floor and sprawled on his back, arms outstretched, still unconscious.

很快地他卸货了他的负担，畏缩如不逐渐地被砰地落下到地板而且在他的背部上扩展的男人，伸开的，仍然无意识的手臂。

Sensible of a benignant persistent ache in his footsoles he extended his foot to one side and observed the creases , protuberances and salient points caused by foot pressure in the course of walking repeatedly in several different directions , then , inclined , he disnoded the laceknots , unhooked and loosened the laces , took off each of his two boots for the second time , detached the partially moistened right sock through the fore part of which the nail of his great toe had again effracted , raised his right foot and , having unhooked a purple elastic sock suspender , took off his right sock , placed his unclothed right foot on the margin of the seat of his chair , picked at and gently lacerated the protruding part of the great toenail , raised the part lacerated to his nostrils and inhaled the odour of the quick , then with satisfaction threw away the lacerated unguinal fragment

随后他弯下身去，解起打成结子的靴带：先掰搭钩，松开靴带，再一次一只只地脱下靴子235 。右边那只短袜湿了一部分，大脚趾甲又把前面捅破并伸了出去，这下于便跟靴子分开了。他抬起右脚，摘下紫色的松紧袜带后，扒下右面那只袜子，将赤着的右脚放在椅屉儿上，用手指去撕扯长得挺长的大拇脚趾甲，并轻轻地把它拽掉，还举至到鼻子那儿，嗅嗅自己肉体的气味，然后就心满意足地丢掉从趾甲上扯下来的这一碎片。

But the effect of her being on those around her was incalculably diffusive: for the growing good of the world is partly dependent on unhistoric acts; and that things are not so ill with you and me as they might have been, is half owing to the number who lived faithfully a hidden life, and rest in unvisited tombs.

但是，她的存在给周围人带来的影响曾经不可胜数地四处扩散：因为世上不断增长的善，部分地是由不具历史意义的行为决定著；而你我周围恶的事物之所以没有像它们本来会成为的那样坏，一半也要归功於那些忠实地过著隐秘的生活，如今安息在无人拜祭的坟茔中的人。

We of course can't deny the significance of transcendent asthetics and consumption asthetics. Because transcendent asthetics can give some critical proposal to the negative and had phenomenons in asthetic and art under market economic condition. Consumption asthetics possibly make some contribution to the research about connection between asthetic and consumption. But we should resolve a series of asthetic problem in the development of China socialism market economic realistically, historically and scientifically (expansively speaking, it's problem confronted by world contempory asthetics, including the connection between consumption and asthetic). We can't drop in some unrealistical and unhistorical fantasy, nor confused by temporary froth and illusion.We still need rely on the development of asthetics of Marxism practicing outlook nowadays.

我们当然不可否认&超越&美学及消费美学存在与发展的意义，因为&超越&美学可能对市场经济发展中，在审美与艺术方面出现的某些消极的、坏的现象提出某种批判的见解，消费美学也可能在研究消费与美的关系上作出某种贡献，但要现实地、历史地、科学地解决中国社会主义市场经济发展中出现的一系列美学问题（扩大开来说，也是当代世界美学面临的问题，包含消费与美的关系问题），既不堕入到各种非现实、非历史的玄想中去，也不为一时的泡沫、幻象所迷惑，仍然要依靠马克思主义实践观美学在当代的发展。

Ten years ago, I saw a girl walking in the street companied by a handsome boyfriend, murmuring softly. I whistled angerily kicking off a stone. Ten years later, I see her again in the street unmanneredly pulling a dirty boy with her bald husband 5 or 6 metre apart.

十年以前在街头看见她神情羞涩地挽着一个英俊挺拔的男友，一边柔声低语着什么，我愤懑地吹起口哨踢飞一粒石子；十年以后又在街头看见她头发蓬松地拉着一个拖鼻涕的男孩，一边厉声呵斥着什么，身后5、6米开外，是她头顶微秃、肚腩渐挺的丈夫。

With the support of a major research grant of Zhejiang Province (No. 001101027) and the Plan of Promoting Education of Excellence of Zhejiang University in the 21st Century, this dissertation is devoted to address the above problems and fabricate an L-band EDFA with low cost, high performance and technological innovation.First the mechanism of an erbium doped fiber amplifier is introduced. Various theoretical models based on classical rate propagation equations are summarized and compared for their applications. We use a modified numerical model based on the Giles model, which agrees with the experimental results well. This serves as the theoretical base for the whole thesis and will be used to optimize the characteristics of EDFAs. A novel method based on a map of noise figure and gain is proposed to analyze efficiently the dependence of the noise figure and gain for EDFAs on the EDF length and the pump power. The characteristics of various EDFAs are studied and compared.Secondly, some important parameters are introduced to describe the characteristics of EDFAs. The methods and the experimental setups for measuring the gain and noise figure of an EDFA are emphasized. We introduce how to measure the characteristics of each component of an EDFA, especially the gain and absorption coefficient of an erbium doped fiber.Thirdly, four types of simple and novel L-band EDFA structures with low noise, high gain and low gain ripple are proposed to satisfy the requirement of a DWDM system. They can be classified into two categories. In the first category, a single ASE pumping is served asa secondary pump. This category includes the following three types. Type: a new construction using a fiber Bragg grating in an unpumped EDF section at the input side. Type: a new structure of L-Band EDFA with two-stage pumps, which utilizes the forward ASE as a second pump.

本论文本着科技创新、服务于生产实践的精神，以设计价格低廉，性能优越、结构合理简单的L-band EDFA为目标，依托浙江省科技厅重大科学基金资助项目(001101027)和浙江大学振兴教育计划资助的全光网络的搭建—《光通信技术》课程实验建设项目，展开了如下工作：首先，介绍了掺铒光纤放大器的工作原理，归纳总结了基于速率方程基础的EDFA的各种理论模型，分析比较了各个模型的特点和适用场合，最终选择完善的Giles理论模型作为本论文分析设计EDFA的理论基础；针对实际实验条件提出了修正的EDFA模型的数值计算方法；创新地提出了增益—噪声系数全局分析法，直观有效地分析了EDFA的增益和噪声系数与掺铒光纤长度和泵浦功率的依赖关系，并对各种EDFA的性能作了全面的比较；第二，介绍了掺铒光纤放大器特性参数的定义与测量方法，重点介绍了噪声系数和增益系数的测量方法及实验装置；介绍了组成掺铒光纤放大器各组件的特性测量方法，重点介绍了测量掺铒光纤参数的方法和实验装置；第三，针对WDM系统对L-band EDFA谱平坦、低噪声、高增益的要求，我们创新地提出了四种不同的L-band EDFA结构，按设计思路可以分为两大类：一类是基于单抽运二级泵浦法，这一类包括在未泵浦掺铒光纤的输入端插入一根布拉格光纤光栅的两段L-band的EDFA的新结构；基于前向ASE光作为二级泵浦源推动下一级EDF工作的泵浦分配、两段级联L-band的EDFA的新结构；基于单根光纤光栅、泵浦分配、两段级联的EDFA；另一类则是基于同时应用前后向C-band ASE作二级泵浦源的双抽运法，如基于前后向ASE光作为二级泵浦源的三段级联L-band的EDFA的新结构。

A new case-matching algorithm, namely ANNI, is proposed in this paper. It uses artificial neural network to setup the mapping relationship, which is generally decided by human expert before and full of unreasonability in weight setting. The ANNI algorithm is proven to be very suitable for mapping between complex-related factor sets and can be applied in case-matching calculation.

首次提出基于BP神经网络的事例匹配度计算—ANNI方法，很好地解决了现有的事例匹配算法需要人为定义权值或匹配规则的缺陷，利用神经网络的自适应性可以有效地确定复杂相关因素集之间的相互映射关系权值矩阵，从而能够有效地应用于基于事例的推理方法中多因素的注塑成型特征集匹配度计算。

A Noiseless Patient Spider A NOISELESS, patient spider, I mark'd, where, on a little promontory, it stood, isolated; Mark'd how, to explore the vacant, vast surrounding, It launch'd forth filament, filament, filament, out of itself; Ever unreeling them--ever tirelessly speeding them.

一只沉默而耐心的蜘蛛一只沉默而耐心的蜘蛛，我注意它孤立地站在小小的海岬上。注意它怎样勘测周围的茫茫空虚，它射出了丝，丝，丝，从它自己之小，不断地从纱绽放丝，不倦地加快速率。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
