But programs set, time of course, amount of curriculum, teaching condition, and teaching form are still insufficient.4The reasons why other universities and colleges do not set elective physical education course are mainly due to leaders" consciousness, quantity and quality of physical education teachers, the field and equipment.5The reform and development of elective physical education course in universities and colleges should incarnate the guideline "health first. people oriented". Teaching content should be pertinent, scientific, arranged, and systematic, so as to build up a teaching content system combined theory, skills and abilities. Set programs on base of students" choice, at the same time, give attention to the requirement of social development and students" interest, and make differential treatment according to gender. The classroom teaching should be sportful, joyful, and successful. The organizing of course could be mutual choice, compensating service, both in and out classroom. The score could be graded synthetically assess knowledge, innovation, and effect.6Strengthening the management to elective physical education course, improving teachers" comprehensive quality, making full use of fields and stadiums are all supporting conditions for the development of elective physical education course.

但是开设的项目、开课的时间、教学时数、教学条件、教学组织形式还难以满足学生学习和掌握知识和技能的需要。4、未开设公共体育选修课的高校其主要原因与领导的认识程度、体育教师的数量和质量、体育场地器材等有关。5、高校公共体育选修课的改革发展应体现&健康第一、以人为本&的指导思想：教学内容突出针对性、科学性、层次性、系统性，构建理论、运动技能、能力培养相结合的内容结构体系；运动项目设置以大学生对体育的选择性为基本前提，同时兼顾社会发展的需要和学生兴趣的需要，注重性别差异与因材施教；教学方法力求教懂、教会，体现课堂教学的娱乐性、快乐感和成功的喜悦：教学组织实施双项选择、有偿服务、课内课外相结合等多种形式；学习成绩实施知识+创新+效果的综合考核评价方法。6、加强公共体育选修课动态管理，提高教师综合素质，挖掘现有体育场馆设施的潜力，充分提高利用率是公共体育选修课改革发展的基本保障条件。

After we had fisht some time and catcht nothing, for when I had Fish on my Hook, I would not pull them up, that he might not see them; I said to the Moor, this will not do, our Master will not be thus serv'd, we must stand farther off: He thinking no harm agreed, and being in the head of the Boat set the Sails; and as I had the Helm I run she Boat out near a League farther, and then brought her too as if I would fish; when giving the Boy the Helm, I stept forward to where the Moor was, and making as if I stoopt for something behind him, I took him by Surprize with my Arm under his Twist, and tost him clear over-board into the Sea; he rise immediately, for he swam like a Cork, and call'd to me, begg'd to be taken in, told me he would go all over the World with me; he swam so strong after the oat that he would have reacht me very quickly, there being but little Wind; upon which I stept into the Cabbin and fetching one of the Fowling-pieces, I presented it at him, and told him, I had done him no hurt, and if he would be quiet I would do him none; but said I, you swim well enough to reach to the Shoar, and the Sea is calm, make the est of your Way to Shoar and I will do you no harm, but if you come near the Boat I'll shoot you thro' the Head; for I'm resolved to have my Liberty; so he turn'd himself about and swam for the Shoar, and I make no doubt but he reacht it with Ease, for he was an Excellent Swimmer.

我们钓了一会儿鱼，一条也没有钓到；因为即使鱼儿上钩，我也不钓上来，免得让那摩尔人看见。然后，我对他说，这样下去可不行，我们拿什么款待主人呢？我们得走远一点。他一想这样做也无妨，就同意了。他在船头，就张起了帆；我在船尾掌舵。就这样我们把船驶出了约三海里，然后就把船停下，好像又要准备捕鱼似的。我把舵交给摩尔小孩，自己向船头摩尔人站的地方走去。我弯下腰来，装作好像在他身后找什么东西似的。突然，我趁其不备，用手臂猛地在他裤裆下一撞，把他一下推入海里。这个摩尔人是个游泳高手，一下子就浮出海面。他向我呼救，求我让他上船，并说他愿追随我走遍天涯海角。他在水里像鱼，游得极快，而这时风不大，小船行驶速度很慢，眼看他很快就会赶上来。我走进船舱，拿起一支鸟枪。我把枪对准了摩尔人，并对他说我并没想伤害他，如果他不胡闹，也不会伤害他。我说：&你泅水泅得很好，你完全可以泅回岸去。现在海上风平浪静，就赶快泅回去吧。我是不会伤害你的。要是你靠近我的船，那我就打穿你的脑袋！我已决心逃跑争取自由了！&他立即转身向海岸方向游回去。我毫不怀疑，他必然能安抵海岸，因为他游泳的本领确实不赖。

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.

Men, at first, for the most part, contented themselves with what unassisted nature offered to their necessities: and though afterwards, in some parts of the world,(where the increase of people and stock, with the use of money, had made land scarce, and so of some value) the several communities settled the bounds of their distinct territories, and by laws within themselves regulated the properties of the private men of their society, and so, by compact and agreement, settled the property which labour and industry began; and the leagues that have been made between several states and kingdoms, either expressly or tacitly disowning all claim and right to the land in the others possession, have, by common consent, given up their pretences to their natural common right, which originally they had to those countries, and so have, by positive agreement, settled a property amongst themselves, in distinct parts and parcels of the earth; yet there are still great tracts of ground to be found, which (the inhabitants thereof not having joined with the rest of mankind, in the consent of the use of their common money) lie waste, and are more than the people who dwell on it do, or can make use of, and so still lie in common; tho' this can scarce happen amongst that part of mankind that have consented to the use of money.

最初，就绝大部分人而言，满足于自然直接提供给他们的生活必需品；然而后来，世界某些部分的种群，（在那里，人口和储蓄的增长，并随着货币的使用，使土地变得不足，因而有了一些价值）多个社群之间确定了他们各自的领土边界，并在社群内部通过法律管理他们社会的私人财产权，于是通过契约和协议，确定由劳动创造的财产权；多个国家和王国之间则订立盟约，以明确表达或默认的形式否认了彼此之间的土地要求和权利，从而，基于共同的同意，放弃了他们原初对于别的国家所拥有的自然的共有权利的要求，于是，通过肯定性的协议，确定他们之间的财产权，在地球上形成各个不同的国家；然而还有大片土地被发现，（那里的居民并未与其余的人类通过使用共同的货币而融合在一起）这些土地处于荒芜状态，多于那里的居民所能够使用，因而仍处于共有状态；不过这种情形很少发生在那些同意使用货币的人群之中。

He bid me observe it, and I should always find, that the Calamitles of Life were shared among the upper and lower Part of Mankind; but that the middle Station had the fewest Disasters, and was not exposd to so many Vicisitudes as the higher or lower Part of Mankind; nay, they were not subjected to so many Distempers and Uneasiness either of Body or Mind, as those were who, by vicious Living, Luxury and Extravagancies on one Hand, or by hard Labour, Want of Necessaries, and mean or insufficient Diet on the other Hand, bring Distempers upon themselves by the natural Consequences of their Way of Living; That the middle Station of Life was calculated for, all kind of Vertues and all kinds of Enjoyments; that Peace and Plenty were the Hand-maids of a middle Fortune; that Temperance, Moderation, Quietness, Health, Society, all agreeable Diversions, and all desirable Pleasures, were the Blessings attending the middle Station of Life; that this Way Men went silently and smoothly thro the World, and comfortably out of it, not embarassd with the Labours of the Hands or of the Head, not sold to the Life of Slavery for daily Bread, or harrast with perplexd Circumstances, which rob the Soul of Peace, and the Body of Rest; not enragd with the Passion of Envy, or secret burning Lust of Ambition for great things; but in easy Circumstances sliding gently thro the World, and sensibly tasting the Sweets of living, without the bitter, feeling that they are happy, and learning by every Days Experience to know it more sensibly.

他说，我自己可以从下面的事实中认识到，中间地位的生活确实幸福无比；这就是，人人羡慕这种地位，许多帝王都感叹其高贵的出身给他们带来的不幸后果，恨不得自己出生于贫贱与高贵之间的中间阶层。明智的人也证明，中间阶层的人能获得真正的幸福。《圣经》中的智者也曾祈祷：&使我既不贫穷，也不富裕。&他提醒我，只要用心观察，就会发现上层社会和下层社会的人都多灾多难，唯中间阶层灾祸最少。中间阶层的生活，不会像上层社会和下层社会的人那样盛衰荣辱，瞬息万变。而且，中间地位不会像阔佬那样因挥霍无度、腐化堕落而弄得身心俱病；也不会像穷人那样因终日操劳、缺吃少穿而搞得憔悴不堪。唯有中间地位的人可享尽人间的幸福和安乐。中等人常年过着安定富足的生活。适可而止，中庸克己，健康安宁，交友娱乐，以及生活中的种种乐趣，都是中等人的福份。这种生活方式，使人平静安乐，怡然自得地过完一辈子，不受劳心劳力之苦。他们既不必为每日生计劳作，或为窘境所迫，以至伤身烦神；也不会因妒火攻心，或利欲薰心而狂躁不安。中间阶层的人可以平静地度过一生，尽情地体味人生的甜美，没有任何艰难困苦；他们感到幸福，并随着时日的过去，越来越深刻地体会到这种幸福。
