本文所做的主要工作包括以下几个内容：一、选取了常见的热膨胀系数大的材料制作封装元件，经过多次一80℃到80℃反复测试，封装元件没有出现老化开裂、封装裂纹、空洞、离层等缺陷，封装材料具有良好的温敏稳定性及复用性，与光纤相容性较好；二、对光纤光栅进行简单、实用的封装处理，就封装效果的优劣性、波长测量的准确度、重复性和封装时产生的波长损失等方面进行了一系列的实验，得出了初步的结论；三、对温敏和温度补偿式封装的实验数据进行了详细的分析和对比，从数字上对温变过程中光纤光栅中心波长的改变及温变曲线进行了定量的分析，在大量实验数据分析结果的基础上，总结出哪种材料封装效果更好，以及如何有效的减小实验误差。

1Niche construction can lead to stable coexistence of diverse genotypes in spatially structured population, which supports a stable polymorphism even without heterozygote superiority.(2)With habitat deterioration, niche construction accelerates the formation of steady polymorphism and hence impedes the harmful influences of environment on the population, which might embody a life-history strategy of organism under the unfavorable environment.(3)Niche construction results in the coexistence with alternative polymorphism through genotype-environment feedback and limited gene flow.(4)The niche-constructing organism is an active force to alter its environment and hence the direction of natural selection in order to better survival.(5)Spatial dynamics and distribution pattern of metapopulation are profoundly influenced by time-lagged niche construction.(6)Metapopulation size can reach a fixed level in the recency effect and equal weighting of time lag but is statistical stability in primacy effect, which implies the primacy effect is most remarkable.(7)The increment in the relative weightingof each generation\' niche construction and the length of time lag are significant factors for system destabilization.(8)Moderate capacity of positive niche construction benefits the metapopulation persistence.(9)The narrowing of niche breadth can decrease the metapopulation size and thereby increase the extinction risk.(10)The coupled function of time lag and niche construction make the system oscillation and generate the spiral wave, spiral-broken and circular wave in heterogeneous habitat.The spatial distributions of metapopulation and resource content are complementary due to a phase lag of their both frequencies.(12)Metapopulation persistence with niche construction depends not only on the balance between colonization and extinction, but also on the balance between the ability of niche construction and natural dissipation of habitat.(13)Metapopula-tion can survive under certain condition when the percent of suitable patches in habitat is lower than the ration of extinction to colonization.(14)Two thresholds exist in the process of transition of habitat quality dynamics from unsuitable to suitable, which include the intensity of niche construction and the initial condition of system.(15)Metapopulation size is positive correlated with the ability of positive niche construction, which means that organism or population who has strongly positive influences on their environment plays an important role to maintain the available habitat.

通过上述几个方面的研究，主要得出以下15条结论：(1)生态位构建可使空间结构种群，甚至是在没有杂合子优势的条件下，形成多种可能的稳定基因型分布模式；(2)随着环境的破坏与恶化，种群的生态位构建作用加速其较早形成稳定多态以阻碍环境对种群的不利影响，解释了有机体在不利环境下的一种生活史对策；(3)生态位构建作用通过基因型—环境反馈机制及有限的基因交流导致基因型多态的稳定共存；(4)有机体的生态位构建作用是一种积极的动力改变环境进而改变其自然选择的方向；(5)生态位构建的时滞作用对集合种群动态和空间分布产生深刻影响；(6)集合种群大小在时滞的崭新效应和等权重效应下达到一固定值，而在首位效应下达到统计稳定，表明首位效应的影响最显著；(7)首位效应下生态位构建相对权重的增量和时滞的长度是影响系统不稳定性动态的关键因素；(8)适中的生态位构建强度有利于集合种群的续存；(9)生态位宽度变窄会减少集合种群的数量从而增加其灭绝风险；(10)时滞和生态位构建的双重作用使系统产生周期振荡，并在异质性环境中产生稳定的螺旋波，破碎的螺旋波和环形波三种分布模式；(11)集合种群与资源含量的空间分布因为相滞而互补；(12)具有生态位构建的集合种群续存不仅取决于侵占率与灭绝率之间的平衡，而且依赖于生态位构建能力同其生境的自然消耗速率之间的妥协；(13)当生境中适合侵占的斑块比例小于其侵占率与灭绝率之比时，生态位构建作用促使集合种群在一定条件下续存：(14)生境斑块的状态从不适合到适合转变过程中存在生态位构建强度和系统初始条件这两个阈值；(15)集合种群的大小同正生态位构建能力正相关，意味着对环境具有较强正作用的有机体对维持有效生境起积极作用。

Being a microcosm himself, he discovers — and it is a true discovery, and he is the man to make it — that the world has been eating green apples; to his eyes, in fact, the globe itself is a great green apple, which there is danger awful to think of that the children of men will nibble before it is ripe; and straightway his drastic philanthropy seeks out the Esquimaux (16) and the Patagonian,(17) and embraces the populous Indian and Chinese villages; and thus, by a few years of philanthropic activity, the powers in the meanwhile using him for their own ends, no doubt, he cures himself of his dyspepsia, the globe acquires a faint blush on one or both of its cheeks, as if it were beginning to be ripe, and life loses its crudity and is once more sweet and wholesome to live.

他是大千世界里的一个缩影，他发现，这是一个真正的发现，而且是他发现的，——世界在吃着青苹果；在他的眼中，地球本身便是一只庞大的青苹果，想起来这却很可怕，人类的孩子如果在苹果还没有成熟的时候就去噬食它，那是很危险的；可是他那狂暴的慈善事业使他径直去找了爱斯基摩人、巴塔哥尼亚人，还拥抱了人口众多的印度和中国的村落；就这样由于他几年的慈善活动，有权有势者还利用了他来达到他们的目的，无疑他治好了自己的消化不良症，地球的一颊或双颊也染上了红晕，好像它开始成熟起来了，而生命也失去了它的粗野，再一次变得又新鲜又健康，更值得生活了。

The output torque is made up of the torque caused by the magnetic field, the torque caused by the plastic viscosity of the MR fluid,and the torque caused by the coulomb friction.

Tent, for the nomad in Chinese history, has been muchly constant as it is the best architecture for the nomad in working. Periodic or aperiodic graze has led in instability of residence and working facility, and tent becomes the sole selection in habitation for thousands of years due to its effective collection and transportation during regular and constant migration.

同样我们再看中国历史上的游牧民族居住的帐篷，之所以长久不变，是因为这是最最适合游牧民族生产作业的建筑功能形式，他们定期或不定期的放牧造成了住所和生产工具的流动性，在经常性的、不断迁徙情况下，帐篷这一简单有效的居住形式因其便于折叠收藏及运输，自然就成了其几千年来不变的居住建筑唯一选择。

Again,he stands there quietly,saying nothing.that's around 5.40am AD 451,in Catalaunian Plain,time freezes at that moment.the sun and the fading moon and stars which has been unchaged for millions and millions of years and will still be unchanged for millions and millions of years and the softened eye lights of hundreds of thousands of brave Roman soldiers are the testimony forever.long time's silence,and general puts on his visor at last and again mounts his horse,he makes a gesture to order his troops to make a circuit,King Theodoric catches up with him,all those soldiers follow closely behind them

那是公元四百五十一年七月二十五日清晨五十四十分左右，时间仿佛在那一刻凝固，那亿万年不变的太阳和那亿万年不变星光以及几十万的罗马战士突然柔和下来的目光是永恒的见证。

The first consequence is that the child will inevitably consider one parent "good", more willing to give in to his desires and the other parent "bad", always ready to prohibit him from doing something. But what makes matters worse is that the child, receiving conflicting messages on the same matter, does not absorb the rule. In other words, as he does not receive clear and univocal messages from the most important people, a child becomes incapable of building up stable reference points, because he acknowledges the concept that there is no such thing as fixed rules and that what parents say can be disputed. A child can also learn to exploit the different points of view to his advantage, turning each time the more permissive parent and ignoring the authority of the more severe one. This can also have important repercussions in the years that follow, because a person who has not learned specific reference points as a child, becomes incapable of respecting the simple rules even at school, at work and those of civil cohabitation. With inevitable consequences from a social and relationship point of view.

第一个我们得到的结论就是小孩子可能会推断只要是能够满足他的欲望的父亲或母亲就是「好的」，而将另一位总是禁止他做某些事情的父亲或母亲当作是「不好的」，但让情况变得更糟的是小孩，在同一个世界当中不断接受到冲突的讯息，但并没有理解这个规则，换句话说，他无法从最重要的人们身上收到清楚、明确的讯息，无法与其建立信赖关系，因为他认知到爸妈说的话是可以被质疑的，且没有任何修改的规则，一个小孩对於他的利益会有不同的观点，只要有一方放纵小孩，而小孩则会去忽视比较严格的那一方，接下来的几年影响力是持续的，因为当他还是孩子的时候他没有去学会那些特定的参考指标，所以就变得没有办法遵循那些很简单的规则，甚至是在学校、工作上或是一般社区的环境，从社交关系上来说这是无法避免的结论。

At length he would reach the corn, and selecting a suitable ear, frisk about in the same uncertain trigonometrical way to the topmost stick of my wood-pile, before my window, where he looked me in the face, and there sit for hours, supplying himself with a new ear from time to time, nibbling at first voraciously and throwing the half-naked cobs about; till at length he grew more dainty still and played with his food, tasting only the inside of the kernel, and the ear, which was held balanced over the stick by one paw, slipped from his careless grasp and fell to the ground, when he would look over at it with a ludicrous expression of uncertainty, as if suspecting that it had life, with a mind not made up whether to get it again, or a new one,or be off; now thinking of corn, then listening to hear what was in the wind.

最后，它终于到了玉米旁，拣定一个玉米穗，还是用那不规则三角形的路线跳来跳去，跳到了我窗前堆起的那一堆木料的最高峰上，在那里它从正面看着我，而且一坐就是几个小时，时不时地找来新的玉米穗，起先它贪食着，把半裸的穗轴抛掉；后来它变得更加精灵了，拿了它的食物来玩耍，只吃一粒粒的玉米，而它用一只前掌擎起的玉米穗忽然不小心掉到地上了，它便做出一副不肯定的滑稽的表情来，低头看着玉米穗，好像在怀疑那玉米穗是否是活的，决不定要去拣起来呢，还是该另外去拿一个过来，或者干脆走开；它一忽儿想看玉米穗，一忽儿又听听风里有什么声音。

Suddenly, the distant sun has twisted, and the light has sparkled too. The captain, known as the "calm orient man", has been shocked at first but not screaming as other colleagues floating beside him. Then he catch the idea that the crystalloid does stand somewhere between them and the sun, the distance of it from them is a couple of miters and from the sun is 100,000,000 miles away.

突然，远方的太阳变形扭曲了，那永恒的光芒也变得闪烁不定，使他吃了一惊，但以&冷静的东方人&著称的他并没有像飘浮在旁边的十几名同事那样惊叫，他很快明白，那块晶体就在他们和太阳之间，距他们有十几米，距太阳有一亿公里。

All the possibilities Things you can pick up and look beneath Just watch your step, Don't fall between the blanks in your memory There's an anchor sinking in the sound of a sense of lack that follows you around Years went by but I know it don't matter what you think of me I'm awake; don't let me go back to sleep Like a fugitive who just quit running Who found out there's no where to escape Some mistakes can't be undone It will never be like it was Wishing for it only makes it worse There's some demons waiting down south Some kind of confederate ghost It holds me close shows me the way to go Until I'm sure I'm lost I built a workshop to find myself Where I can dig in the corners climbing spider webs It's a polaroid cemetery of every look you're ever given me I'm awake; don't let me go back to sleep Like a fugitive who just quit running Who found out there's no where to escape Some mistakes can't be undone It will never be like it was Wishing for it only makes it worse Keep on riding capture feeling It's an outline of a real connection Treat your desires as what they are Imposters and lonely invitations Some mistakes can't be undone It will never be like it was Wishing for it only makes it worse
