还有一个小玻璃瓶，里面装着加了芳香剂的糖果。中层放着一只盛了胡椒粉的有缺口的蛋杯，饭桌上还摆着那种鼓状食盐瓶，用油纸包着的四颗粘成一团的黑色橄榄，一听李树商标肉罐头的空罐儿，垫着纤丝的椭圆形柳条筐里是一只泽西梨，喝剩下的半瓶威廉。吉尔比公司釀造的药用白葡萄酒（裹在瓶子上的粉珊瑚色薄绘纸已剥掉了一半），一包埃普斯公司制造的速溶可可；一只绉锡纸袋里装着安妮。林奇公司出品的五英两特级茶叶，每磅二先令；一只圆筒形罐子，盛着优质结晶角沙糖；两颗葱头，较大的那颗西班牙种的是完整的，较小的那颗爱尔兰种的已经切成两瓣儿，面积扩大了，气味也更冲鼻了；一罐爱尔兰模范奶场的奶酪，一只褐色陶罐，盛着四分之一品脱零四分之一兑了水并变酸了的牛奶（由于炎热，它已化为水、酸性乳浆与半固体凝乳，再加上布卢姆先生和弗莱明大妈作为早餐消费掉的部分，就足够一英品脱了，相当于原先送来的总量）；两朵丁香花蕾，一枚半便士硬币和盛有一片新鲜排骨肉的一个小碟子。

In this thesis,based on the DFT+NEGF first-principles method,we construct a lead-molecule-lead sandwich system with single benzene-based molecule to investigate the relationship between the structure and properties of the molecular devices and the factors that influence properties of the molecular devices.Our computational investigations on these molecular devices are primarily concentrated on the effect of contact geometry between molecules and electrodes,the effect of side groups,the effect of different torsion angle between two phenyl rings and the effect of external electric field.This thesis consists of five chapters:In Chapter one,we mainly introduce the research background and development of the molecular electronics,including the experimental fabrication of molecular electronic components and theoretical simulation methods.Afterwards we discuss the questions that need to be solved in this area.Finally,the main contents of this thesis are listed.In Chapter two,we introduce the theoretical methods used in this thesis, including the main first-principles calculation methods,i.e.,the Density-Functionmethod and nonequilibrium Green\'s function.

There is a small action range in archery.Simple methods and analysis is inadequate,so the author,on the basis of testing the archery athletes in national team with the Qualisisy infrared photoelectric testing system,Footscan sole pressure testing system,Noraxon myoelectricity remote testing system, etc,analyzes comprehensively the action technique of the athletes in national team from the posture,body motion characteristics,body posture equilibrium and stability,distribution of centre sole pressure, myoelectricity characteristics,etc,with the methods of relative software and data statistics.The conclusions and the suggestions are as follows:Conclusion:Firstly,the communality of posture angle,muscle strength,the activation order of main muscle during raising the bow, raising the bow and the timing of the raising could be used as the evaluation index of technique action in archery;Secondly,the length of the time needed in the different periods couldn\'t be used as technique evaluation index since it has no relation with the result.But the time of raising and pulling back the row is relatively fixed,and the time has a positive relation with the archery achievement of the national team in China.Thirdly,the central index of the sole pressure could be used as the reference criterion of selecting athletes and forecasting achievement.During playing archery,the interrelation between the central index of the sole pressure and the achievement is different individually and in different periods.Fourthly,there is low stability of the archery athletes in the front and back direction during the action, caused by the athletes\' posture disequilibrium of dorsal abdominal muscle and non-professional sport shoes..Fifthly,kinematics and electromyography shows that the people on archery in China haven\'t taken the raising and pulling back the row seriously.

射箭的肢体动作幅度小，简单的手段和分析不能满足其需要，笔者结合各种运动生物力学仪器优点及射箭项目的特性，选用Qualisisy红外光点测试系统、Footscan足底压力测试系统、Noraxon肌电遥测系统等对国家队射箭队运动员进行多方位的测试，运用相关软件及数理统计方法，对运动员的射箭动作技术，从射箭动作的姿态构架、肢体运动特点，身体姿态平衡稳定性、足底压力中心分布、肌电特性等进行全面分析，结论及建议如下：结论：第一，姿态角、肌肉用力激活程度、举弓阶段主要用力肌肉激活顺序、举弓、开弓时间等的一致性可作为射箭技术动作评价指标；第二，各动作阶段所用时间的长短不能作为技术评价指标，但举、开弓的时间相对较固定，开举弓时间比与中国国家队射箭成绩正弱相关达到显著性；第三，闭眼状态下足底压力中心单位面积轨迹长与144支箭最好成绩正相关达到显著性，可作为身体素质、选材及成绩预测的参考依据；实射时身体平衡的足底压力中心指标与成绩的相关程度具有个体性差异、阶段性差异；第四，射箭运动员实射时身体在前后方向上的稳定性较差，这与运动员的站立姿态、腹背肌力量的不匹配以及射箭没有专业运动鞋有关；第五，运动学及肌电学都表明中国射箭训练对举弓、开弓阶段的重视不够，背部肌肉用力特征不明显，撒放技术合理性不高。

NodD binds to and bends target promoters through anchoring two tandem and individual specific DNA sites. NodD functions as a tetramer, which has a V-shaped main body. Tetrameric NodD is to change its own conformation rather than its oligomeric forms in response to small signal molecules. The specific interaction between each NodD DNA-binding domain and each specific DNA site does not alter itself in spite of naringenin induction, and the induced conformational change is transferred from protein to DNA. Only the DNA conformation incited by induced NodD is competent for RNA polymerase to form the transcriptional open complex. It cannot be excluded that NodD may have protein-to-protein contacts with RNA polymerase, and that the NodD conformational change may also directly contribute to the transcriptional open complex formation. However, the NodD conformational change itself cannot serve as the determinant of the transcriptional molecular switch.

通过研究，我们提出了初步的NodD操纵子激活模型：第一，四聚体是NodD蛋白的功能单位，它通过铆钉两个串联的相对独立的DNA靶位点结合被诱导的启动子；第二，小分子配基的结合是改变NodD四聚体的构象而不是引发不同形式的寡聚体，在我们的模型中，NodD四聚体缩小其V形主体的弯折角，进而缩短其DNA结合功能域的间距；第三，小分子信号的诱导并没有改变NodD的DNA结合域和其DNA靶位点的相互作用，NodD的构象改变由蛋白质经其双铆钉位点传递给DNA；第四，只有诱导状态的NodD激发的DNA构象才能有效地使RNA聚合酶形成转录开放复合物；第五，不排除NodD与RNA聚合酶可能有直接的相互接触位点，不排除NodD构象的改变可能直接有利于RNA聚合酶形成转录开放复合物，但是我们认为NodD构象改变本身不是充当转录激活开关的决定因素。

Squatting, lying, and milling aimlessly about the lower level were a dozen of so large lizard-like beasts that looked like the product of some mad geneticist's cross of Tatooine krayt dragons wit h Haruun Kal ankkoxen : four meters tall at the shoulder, long crooked legs that ended in five-clawed feet clearly designed for scaling rocky cliffs, ten meters of powerful tail ridged with spines and tipped with a horn-bladed mace, a flexible neck leading up to an armor-plated head that sported an impressive cowl of spines of its own—they looked fearsome enough that Obi-Wan might have thought them some sort of dangerous wild predators or vi cious watchbeasts, were it not for the docile way they tolerated the team of Utai wranglers who walked among them, hosing them down, scraping muck from their scales, and letting them take bundles of greens from their hands.

在下层那儿，蹲着的，躺着的，或是在漫无目的地殴斗的，是整整一打类似蜥蜴的巨型野兽，它们看上去就像是某个科学狂人将塔图因的克雷特巨龙和哈伦·卡尔的安科森兽糅合在一起的成品：肩高四米，长而弯曲的腿的末梢长着五根用于攀登岩壁的爪子，十米长的强壮尾部上扎满了尖刺，末端是一个尖角满布的骨槌，柔韧的颈部支撑着一个布满铠甲的脑袋，脑袋上又炫耀着一簇可怕的尖刺——它们的长相实在太恐怖了，使得欧比旺不禁觉得这些家伙不是危险的野生掠食者，就是冷血的守卫神兽，可恰恰相反，它们在那些尤泰牧人面前却表现得十分乖巧温顺，任由他们从中穿行，往它们身上浇水降温，从它们的鳞片上刮去污物，以及将一捆捆青草递到它们嘴边。

Having undertaken for the Glory of God, and Advancement of the Christian Faith, and the Honour of our King and Country, a voyage to plant the first colony in the northern parts of Virginia; do by these presents, solemnly and mutually in the Presence of God and one of another, covenant and combine ourselves together into a civil Body Politick, for our better Ordering and Preservation, and Furtherance of the Ends aforesaid; And by Virtue hereof to enact, constitute, and frame, such just and equal Laws, Ordinances, Acts, Constitutions and Offices, from time to time, as shall be thought most meet and convenient for the General good of the Colony; unto which we promise all due submission and obedience.

我们在上帝面前共同立誓签约，自愿结为一民众自治团体。为了使上述目的能得到更好地实施、维护和发展，将来不时依此而制定颁布的被认为是对这个殖民地全体人民都最适合、最方便的法律、法规、条令、宪章和公职，我们都保证遵守和服从。据此于主后l620年11月11日，于英格兰、法兰西、爱尔兰第十八世国王暨苏格兰第五十四世国王詹姆斯陛下在位之年，我们在科德角签名如下。因为这一段文字，第一次从民众的角度阐述了国家权力的来源：国家是民众以契约的形式合意组建的，国家的公权力来自于民众所度让的部分权利的组合。法律实施的真正力量源于民众对于国家法律合法性与公正性的认同，出于对法律的敬畏而自愿服从，而不是慑于国家暴力。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。
