Using the one-atom theory, the electronic structures of Pt-electrocatalyst with fcc structure was determined as follows:(5dn)6.48 (5dc)2.02 (6sc)1.48(6sf)0.02. Compared to the result obtained by the first-principle method such as FP-LMTO, CASTEP, their results are in good agreement with each other. Comparing the calculations of physical properties such as lattice constants, cohesive energy and bulk modulus by OA method and first-principle method, the result obtained by OA method is in excellent agreement with experimental value, but the result obtained by first-principle method is not accordable. The relationship between the electronic structures and catalytic performance was explained qualitatively by OA method and first principle method according to its electronic structures. Because the d-orbital vacancies increases and static density is high around Fermi energy band, Pt has good catalytic performance.

摘 要：依据纯金属单原子理论确定面心立方结构电催化剂Pt的电子结构为(5dn)6.48(5dc)2.02-(6sc)1.48(6sf)0.02，与采用第一原理的FP-LMTO和CASTEP等方法所计算的电子结构相比较，其结果非常相近；由OA理论和第一原理方法计算的晶格常数、结合能、体弹性模量等物理参数进行比较，OA理论计算的结果与实验值较符合，而第一原理方法计算的结果与实验值相差较大；在此基础上用OA理论和第一原理方法研究了Pt的电子结构与催化性能的关系，由于d带空穴增多和费米能级附近态密度较高，导致金属Pt的催化性能很好。

After research we can find that: firstly, a great number of predicate-word phrases can act as the adnex of the verb-complement structure; secondly, almost all the verbal phrases and adjectival phrases can act as complement, and other phrases like adverbs, noun, quantifier phrases, some prepositional phrases and subject-predicate phrases, even compound sentence can act as complement too;thirdiy, there are six kinds of verb-complement structures in the novel;fourthly, the verb-complement structures can act as subject, predicate, object, attribute, adverbial modifier, complement in a sentence and other phrases component, even can be a sentence by itself; fifthly, the semantic connection between complement and other components in the sentence is very abundance and complex;sixthly, some special verb-complement structures in the Dream of the Red Chamber show the characteristic of transitional language.This thesis is divided into five parts:Part 1: Preface.

通过研究我们可以发现：首先，大多数的谓词性词语在《红楼梦》中都可以充当述补结构的述语；其次，几乎所有的动词性词语和形容词性词语都可以充当补语，少数副词和名词性词语也可以做补语，数量短语、介宾短语、主谓结构和复句也可以做补语；第三，述补结构的类型按中间的助词标记可以分为没有助词的，有&得/的&的，有&个&的，有&着&的，有&将&的和有&到&的六种；第四，述补结构可以充当主语、谓语、宾语、定语、状语、补语以及各种成分内部的组成成分，还可以单独成句，其语法功能非常丰富；第五，补语的语义指向是多方面的，语义内容非常复杂；第六，几种特殊的述补结构说明了《红楼梦》的述补结构带有过渡时期的特点。

The Chinese light verbs supported by neuromechanism can explain the generative question in Chinese interchangeable phrases, causative structures, reverse factitive structures and verb-complement structures. All these questions can be marked by causative in the lexical feature and moving in syntax. All the conclusions demonstrate that we can unify the explanations of Chinese syntax and lexicon by light verbs. Therefore light verbs are the interface among brain, lexicon and syntax.

具有神经基础支持的汉语轻动词理论可以解决汉语可变换位置词组、使动句、反转型使役句以及动补结构等句子的生成问题，而这些问题在轻动词词汇特征上可以用&致使&性来统一标示，在句法特征上可以用&移位&来统一操作，从而表明汉语轻动词可以实现词法句法的统一解释，轻动词研究是大脑、词库以及句法研究的结合点。

First, the actuality of Jiangyin bridge's deck surfacing are reviewed. Improper materials and pavement structures, severe conditions, overload and heavy traffic are deemed to be the main factors which result to deterioration of the deck surfacing. Then, programme of local repair asphalt mixture design has been proposed. It is considered that epoxy asphalt mixture and guss asphalt mixture are propitious to the local repair. The epoxy asphalt is also chosen as the adhesive layer material. Next, two pavement structures for steel deck plate surfacing have been tested. The most suitable asphalt surfacing structures have been proposed for the local repair. Finally, the elaborate local repair schemes of Jiangyin bridge's deck surfacing are proposed.

Since inextensible reinforcements do not stretch under design loading, they are the preferred MSE reinforcement type for highway structures in general and for critical structures such as bridge abutments in particular, where deformation control is crucial to structural performance of both the superstructure and the abutment.5 Inextensible reinforcements have been used successfully in MSE bridge abutment structures for thirty-five years, while research is still underway trying to develop an extensible

由于不可拉伸的加筋体在设计承载下不能拉伸变形，因此它们一般是公路结构，尤其是桥肩等重要结构中的首选材料，因为在这些结构中，变形控制对上层建筑和桥肩中性能表现是很关键的因素。不可拉伸加筋体在加筋土桥肩结构中已经成功的使用了35年，与此同时，研究能够在桥肩应用中性能有保证的可拉伸加筋体的工作正在进行中。
