Of swimming creatures that are destitute of feet, some have winglets or fins, as fishes: and of these some have four fins, two above on the back, two below on the belly, as the gilthead and the basse; some have two only,-to wit, such as are exceedingly long and smooth, as the eel and the conger; some have none at all, as the muraena, but use the sea just as snakes use dry ground-and by the way, snakes swim in water in just the same way.

一些没有脚的动物有小翼或者鳍，如鱼；这样的动物有些有四只鳍，两只在背上，两只在腹部，如乌颊鱼和 BASSE ；一些只有两只鳍，理智的说，就如那些极度修长和平滑的鳗鲡和康吉鳗；一些动物没有鳍，如同 MURAENA ，但是在海里就如同蛇在陆地，并且顺便说一下，蛇在水里游也是使用同样的方式。

Liverpool have a Midlands double-header after Christmas, hosting Wolves on Boxing Day before travelling to Villa just two days later. Although it could be much worse during a congested part of the football calendar, the fixture compilers have been kinder to both United (Hull away on the 26th, Wigan at home on the 28th) and Chelsea (Birmingham away on the 26th, Fulham at home on the 28th). Villa Park has been something of a happy hunting ground for Liverpool in recent years, though. It was 1998 when the Reds last tasted defeat there, after two Collymore goals completed a comeback for the home side who had gone behind to an early Michael Owen penalty. Since then, though, Liverpool are undefeated at Villa's ground, winning six and drawing five of their last 11 visits.

但是利物浦在圣诞节后，有两场重头戏现在节礼日做客狼队，然后两天后飞往维拉，相对于曼联（26号客场胡尔城，主场28号维甘）和切尔西（客场26号伯明翰和28号主场富勒姆），利物浦的赛程要糟糕得多，最近几年维拉公园总是利物浦得分天堂，尽管1998年利物浦1比2在维拉饮恨，当欧文点球首开纪录后，柯利莫尔的两粒进球帮助维拉取得胜利，自那时起，利物浦在维拉未尝败绩，他们在11场做客维拉的比赛中6胜5平。

Based on the analysis of the Jahn-Teller effect,vibronic interaction and the resolution of group representations, the possiblegcometrical configurations of 〓 have been derived for the first time, the results arein good agreement with the calculation esults.Firstly, the reasonable dissociative limits for the diatomic molecules of ZrCo,ZrH, CoH, UH,〓 and AlNi have been derived based on the Atomic and MolecularReactive Statics and the resolution of group representations. The groundelectronic states, which are 〓,〓,〓 and 〓 respectively for thesemolecules, have also been optimized based on the RECP method.

本文根据相对论有效原子实势和密度泛函理论方法(B3LYP／SDD与B3LYP／6-311G〓)，用Gaussian-98W程序研究了ZrCo、ZrH、CoH、UH、〓、AlNi、〓、HZrCo和〓分子的分子结构、分析势能函数、微观力学性质和光谱性质；首次建立了计算固体金属氢化物体系宏观性质理论模型，并应用于ZrCo、Zr和Co的氢化反应体系研究，理论计算与实验结果基本一致；基于Monte-Carlo准经典轨线方法，首次研究了H与ZrCo和Co与HZr的分子反应动力学。

By using all of the above actions, the best benefits can finally be perused. For most of construction enterprises that have the funds problem, to clear up the old debt is their first step, so as to making full use of the funds and guarantee the enterprise's strength. The enterprise with powerful strength will have more opportunities to choose the superior projects, which has a comparative advantage on the cost control and a well credit standing on the recycling of the project funds. Then more funds the enterprise will have and the strength is powered at the same time. On this benign circle, the enterprise's benefit is surly guarantied. What's more, it will set up a bright flag in the comparatively confused construction profession market.

对于大多数被资金困扰的建筑施工企业而言，清理旧帐是第1步，用活资金，保证实力；实力有了，就有更多的机会选择质优工程；对于质优工程，成本相对来说比较好控制，而且工程款的回收也有保障；然后就有更多的资金，更好的实力……在企业实现自身良性循环的同时，效益当然有保障，更重要的是给相对比较混乱的建筑施工行业市场树立1面鲜明的旗帜。

The innovations of the thesis have been shown in several aspects as follows: put forward the transfer mechanism model of the landslide thrust on basis of the soil arching theory, and according to the model the formula about how to compute the thrust acting on the pile and the maximum pile spacing have been deduced. Set up the displacement model about the interaction of the pile and landslide, and their relatively displacement can be taken into consideration when computing the pile, thus the limitation of supposing the distribution of landslide thrust has been avoided, at the same time, the applied condition of the model and the computing procedure have been given. Bring forward the improved computing method of the anti-sliding pile with prestressed cable, which has been verified rational and applicable, making the method more perfectly in theory. Through the study on the mechanical model of the foundation beam with prestressed cable, put up the limit design idea of the structure, and the realization procedure of the idea has been given and programmed with the finite element, which leads to a new thinking for the safe and rational design of the foundation beam with prestressed anchor cable.

本论文的创新之处在于，用土拱理论建立了滑坡推力在抗滑桩与坡体之间的传递机制模型，并由此得到了作用于抗滑桩上的滑坡推力计算式以及最大桩间距的确定条件式；建立了抗滑桩与滑坡体相互作用的位移模型，该模型能考虑桩与坡体相互作用过程中二者相对位移的影响，避免了人为假设滑坡推力分布形式的缺陷，给出了其适用条件和计算过程；提出了预应力锚索抗滑桩的改进计算方法，使得预应力锚索抗滑桩的计算理论更加完善，通过实例验证了该方法的适用性和合理性；在预应力锚索地梁力学计算模型研究的基础上，提出了预应力锚索地梁极限状态设计的新思想，给出了该设计方法的实现途径并编制了有限元计算程序，为锚索地梁合理而安全的设计提供了一种新思路。

Where our dogmatists err on this question is that, on the one hand, they do not understand that we have to study the particularity of contradiction and know the particular essence of individual things before we can adequately know the universality of contradiction and the common essence of things, and that, on the other hand, they do not understand that after knowing the common essence of things, we must go further and study the concrete things that have not yet been thoroughly studied or have only just emerged.

例如，无产阶级和资产阶级的矛盾，用社会主义革命的方法去解决；人民大众和封建制度的矛盾，用民主革命的方法去解决；殖民地和帝国主义的矛盾，用民族革命战争的方法去解决；在社会主义社会中工人阶级和农民阶级的矛盾，用农业集体化和农业机械化的方法去解决；共产党内的矛盾，用批评和自我批评的方法去解决；社会和自然的矛盾，用发展生产力的方法去解决。

I sometimes dream of a larger and more populous house, standing in a golden age, of enduring materials, and without gingerbread work, which shall still consist of only one room, a vast, rude,substantial, primitive hall, without ceiling or plastering, with bare rafters and purlins supporting a sort of lower heaven over one's head —— useful to keep off rain and snow, where the king and queen posts stand out to receive your homage, when you have done reverence to the prostrate Saturn of an older dynasty on stepping over the sill; a cavernous house, wherein you must reach up a torch upon a pole to see the roof; where some may live in the fireplace,some in the recess of a window, and some on settles, some at one end of the hall, some at another, and some aloft on rafters with the spiders, if they choose; a house which you have got into when you have opened the outside door, and the ceremony is over; where the weary traveller may wash, and eat, and converse, and sleep, without further journey; such a shelter as you would be glad to reach in a tempestuous night, containing all the essentials of a house, and nothing for house-keeping; where you can see all the treasures of the house at one view, and everything hangs upon its peg, that a man should use; at once kitchen, pantry, parlor, chamber, storehouse,and garret; where you can see so necessary a thing, as a barrel or a ladder, so convenient a thing as a cupboard, and hear the pot boil,and pay your respects to the fire that cooks your dinner, and the oven that bakes your bread, and the necessary furniture and utensils are the chief ornaments; where the washing is not put out, nor the fire, nor the mistress, and perhaps you are sometimes requested to move from off the trap-door, when the cook would descend into the cellar, and so learn whether the ground is solid or hollow beneath you without stamping.

我有时梦见了一座较大的容得很多人的房屋，矗立在神话中的黄金时代中，材料耐用持久，屋顶上也没有华而不实的装饰，可是它只包括一个房间，一个阔大、简朴、实用而具有原始风味的厅堂，没有天花板没有灰浆，只有光光的椽木和桁条，支撑着头顶上的较低的天，——却尽足以抵御雨雪了，在那里，在你进门向一个古代的俯卧的农神致敬之后，你看到衍架中柱和双柱架在接受你的致敬；一个空洞洞的房间，你必须把火炬装在一根长竿顶端方能看到屋顶，而在那里，有人可以住在炉边，有人可以往在窗口凹处，有人在高背长椅上，有人在大厅一端，有人在另一端，有人，如果他们中意，可以和蜘蛛一起住在椽木上：这屋子，你一打开大门就到了里边，不必再拘泥形迹；在那里，疲倦的旅客可以洗尘、吃喝、谈天、睡觉，不须继续旅行，正是在暴风雨之夜你愿意到达的一间房屋，一切应有尽有，又无管理家务之烦；在那里，你一眼可以望尽屋中一切财富，而凡是人所需要的都挂在木钉上；同时是厨房，伙食房，客厅，卧室，栈房和阁楼；在那里你可以看见木桶和梯子之类的有用的东西和碗橱之类的便利的设备，你听到壶里的水沸腾了，你能向煮你的饭菜的火焰和焙你的面包的炉子致敬，而必需的家具与用具是主要的装饰品；在那里，洗涤物不必晒在外面，炉火不熄，女主人也不会生气，也许有时要你移动一下，让厨子从地板门里走下地窖去，而你不用蹬脚就可以知道你的脚下是虚是实。
