At the same time, This part elaborate detailedly his transformation of his poems style, from simulate to mature, which relates to his vagabondage .

同时，这一部分对其各个时期诗风的转变进行了详细的阐述，从最初的模拟之作到最终走向成熟，无不与其漂泊的人生有着密切的联系；第三部分对汪元量诗歌创作进行成因分析，揭示出蒙元统治是汪元量诗歌创作的政治动因，宽松的文化环境是他诗歌创作的契机，而"宗唐得古"风尚，则是汪元量诗歌创作的温床；第四部分对汪元量研究中存在的"宋旧宫人诗词真伪"和汪元量仕元两个问题进行了更加全面、更加科学的论述，揭示出王国维先生提出的宋旧宫人诗词为伪作这一观点不能成立。

The Mo center of [Mo8](superscript 4)-shows a slight distorted square antiprism coordination environment. The N atoms of cyano groups, acting as acceptors of hydrogen bonds, together with protonate N atoms from organocations and the lattice water, serving as donors of hydrogen bonds, form intricate hydrogen bond interactions, thus generating three-dimensional supramolecular network with the help of π-π interactions of some organocations.

Mo8(上标 4-)离子中，Mo中心处于扭曲的反四棱柱配位环境。8个未配位的氰基氮原子作为氢键的受体，有机阳离子上质子化的氮原子和结晶水作为氢键的给体，形成了丰富的氢键作用，这些氢键作用连同部分有机阳离子间的π-π堆积、阴阳离子间的静电力和Van Der Waals力构筑成三维超分子网络。

By describing Pythagorean theorem, the first time-space view explain the plane-line thought which impacts human's thinking manner; the second time-space view is absolute time-space theory of Newton and three-dimensions space-time view intersected by space-time; the third space-time view is curve space-time view which is generated from Einsteinian relative theory. The fourth space-time view is the directional, irreversible entropy time-space thought; the fifth time-space view is dense time-space view of cracked fractal generated from chaos-fractal theory.

第一时空观是通过对勾股定理的描述来说明影响人们思维方式的平直时空观；第二时空观是牛顿的绝对时空理论，是时空分割的立体三维时空观；第三时空观是爱因斯坦的相对论理论所带来的弯曲时空观；第四时空观是具有方向不可逆的熵时空观；第五时空观是混沌与分形理论所带来的破碎分形的稠时空观。

The wave function of the phonon is assumed to take thecoherent state,a self-consistent integrodifferential equationsatisfied by the electron wave function is derived.Solving for thisequation,we get the polaron ground-state energy E=-0.1085α2, whichis very close to these of previous strong-coupling theories.In chap.4,we will apply approaches developed in chaps.2 and 3 to discuss theimportant two-dimensional(2D)polaron problem.

把声子部分取成相干态的形式，我们推导出电子波函数所满足的非线性的微分积分方程，求解这个方程，我们得到基态能为E＝-0.1085α2，它与以前的各种强耦合理论的结果非常接近，在第四章中，我们利用在第二，三章中发展的方法讨论很重要的二维极化子问题。

Several early 14th-century theorists referred to the idea of an Ars Antiqua, represented primarily by Franco, and an Ars Nova instituted by Philippe de Vitry(see, for instance, CoussemakerS, iii, 371,408),but in historical terms the usefulness of the idea is supported more by the treatise Ars novae musicae(c1320)of Johannes de Muris, the 1324-5bull lf Pope John XXII decrying the musicians who were 'novellae scholae discipuli' and the reference in Jacobus of Liege's Speculum musice to 'moderni cantores' and to'aliquinunc novi'.

一些十四世纪早期的理论家已经谈到以弗朗科为首要代表的古艺术的观念，新艺术是由维特利建立起来的，但从历史角度来看，这一观念的实用价值更多是由穆里斯的论文《新音乐艺术》、1324-1325年教皇若望二十二世贬斥那些&信奉新学派&的音乐家们的训令，以及列日的雅各布的《音乐明鉴》中所提到的&当代歌手&和&一些现在的认识&支撑着。

Scanning electron microscopy,transmission electron microscopy,circular dichroism and small-angle X-ray diffraction were used to analyze the aggregation mode of CSG in the organogel phase.A hierarchical self-assembly model was proposed to explain the transition from molecular to primary and secondary structure.It is shown from our results that CSG can aggregate into a micellar fibril nanostructure with high length-to-width ratio which is bundled and entangled to form a three-dimensional(3D) network that immobilize the fluid component probably by surface tension.Moreover,sol-gel polymerization of tetraethoxysilane was carried out using CSG in the gel phase.

通过扫描电镜(ScanningElectron Microscopy，SEM)、透射电镜(Transmission Electron Microscopy，TEM)、圆二色谱(Circular Dichroism，CD)和小角X—射线衍射仪(Small-angle X-rayDiffraction，SAXRD)考察CSG分子自组装行为结果表明，CSG形成的聚集体具有多级结构：首先CSG通过手性堆叠自组装形成直径在9—10nm的细纳米纤维，这些细的纳米纤维再以不规则的六方堆积的方式进行排列，构成直径在40—100nm的粗纳米纤维(即细纳米纤维的&捆束&)，最后粗纳米纤维互相粘连形成三维网络状结构，使有机溶剂&固定&，从而形成凝胶；以CSG有机凝胶为模板，四乙氧基硅烷为前体，通过溶胶—凝胶聚合的方法制备了直径大约为100nm的二氧化硅纳米管。3。

Methods: The motion of parasternal papillary muscle anterior wall, inferior wall, posterior wall, and lateral wall were detected by 2DE at short axis view of left ventricle before PTCA, 3 d and 1-3 months after PTCA in 33 cases of patients with coronary heart disease, who received PTCA+stent at selected time. Peak systolic velocity of subendocardial, subepicardial and middle layer myocardium, transmural velocity difference of the same segments and Outer lateral mitral valve annulus were also detected at apical 4 chamber view by pulsed wave tissue Doppler imaging.

EyelinkⅡis used in experiment 3 to study the external and internal refence fame inmental rotation. The result is that presenting a number with an external referenceframe, subjects\' internal reference frames can be revised. At the same time, thesubjects tend to use frame rotation.

研究四的两个实验分别采用了汉字数字与阿拉伯数字以及经典的心理旋转的三维立体图形探讨了心理旋转中的表象表征与命题表征的转化，发现表象表征的容量组块是4，在4以下时，表象表征占主导地位，心理旋转采用表象的匹配，但在容量组块超过4时，命题表征的优势显现了出来，对于刺激物的整体加工的效果更为明显。

To systematicallyinvestigate this landmark, we conducted a study in four phases:1 Two blindfolded examiners determined the distance betweenthe tuberosity's medial border and the clavicle's lateral endin 100 dried clavicles and then 2 performed subclavian veincannulation in 20 fresh human cadavers using the tuberosityand the suprasternal notch as landmarks. 3 Three-dimensionalreconstructions of the subclavian artery and vein and surroundingstructures were derived from computed tomography datasets of10 patients. The length of the path of a virtual subclavianvein cannulation with the deltoid tuberosity landmark was measuredbilaterally. 4 In a prospective, randomized trial, subclavianvein cannulation was performed in 60 patients with a standardapproach or with the deltoid tuberosity as landmark.
