就方法而言，侯易的模式比韩礼德和哈桑的更具创造性，它提供了一种分析句间词汇衔接的新方法；就理论而言，侯易有关语篇中词汇模式的详细分析强调词汇衔接手段比其他衔接手段更重要；就操作而言，侯易对联结紧密的词汇衔接手段的矩阵分析准确反映了它们间的非线性复杂关系，更便于我们处理和阐释这些关系。

These results were supported by both token and type analyses. Lexical aspect was found to be a more forceful constraint on the simple past marking than phonetic saliency: Among the more advanced learners, the distinctions across the four lexical aspectual categories in the simple past marking were still statistically significant while the distinctions across the categories of saliency features were only significant in the lower level groups.

以上这些结果都同时得到频数分析和类型分析的支持相比而言，情状体对一般过去时标记的影响大于凸显度，其表现为在较高水平的学习者中各情状体分类间标记的差别仍具有统计学显著意义，而语音凸显度的影响仅在低水平组有显著表现。

The conclusions are as follows:(1) Neologisms in each Huayu region can be classified into two major categories:self-originated and others-originated,among which the new-born words are "absolute new words" and the inherited word are "relative new words",and there are also others-originated elements in the morphemic and sense systems of new words;(2) Variation can be seen in the morpheme,formation,building and sense of new words in Huayu regions,besides individuals of new words;(3) Aggregation of current new words and compound words with one common morpheme and a same construction,together with the aggregation of synonyms and that of different senses in polysemies,reflect the relevance of the systems of new words in Huayu regions in their variation;(4) Regular participation of hinting sense of a formation element in forming and building new words is an important way of producing new sense of morpheme,and an important reason for the current emergence of words with more than one new senses;(5) Compared with ordinary words,the productivity of ways of word formation in forming new words both in general and of a particular class will change and new ways of word formation appear in Huayu regions;(6) The semantic collocation of the verbal morpheme of new verbs in a phrase has a great influence on the location of its structural center,and the complex syntactic behaviors of new verbs are related to the different processes of argument integration;(7) The processes of building new words with the same meaning differ in levels of approaches to motivation cognition,perspectives of motivation cognition,morpheme motivation and morpheme expression,etc.;(8) The lexical interaction in Huayu regions results in lexical subsystem intersections of current new words across two,three and four regions.

本文的主要结论是：(1)各华语区新词均可分为"自源新词"和"他源新词"两大类，其中的新生词和传承词分属"绝对新词"和"相对新词"，新词语的词素、词义系统中也含有他源成分；(2)除词语个体外，华语区新词在词素、构词、造词、词义等方面均体现了某种程度的变异：(3)通用词语聚合、同素同构词聚合、同义异形词聚合与一词多义聚合集中反映了各华语区新词语系统在变异中的关联；(4)构词单位经常提示词义参与构造新词是产生新语素义的重要途径，也是当代多新义词现象的重要成因；(5)相对于一般词语，构词方式在新词语中的总能产性和在某一词类中所体现的能产性都有所变化，华语区也产生了新的构词方式；(6)新动词的动素在短语中的语义搭配对结构核心的位置有很大影响，新动词的复杂句法表现与不同的论元整合过程有关；(7)同义新词造词过程的差异包括理据认知途径、理据认知角度、词素理据和词素表达等不同层面；(8)华语区的词汇互动形成了双区、三区和四区通用新词等词汇子系统交集，作为华语核心，普通话所含纳的通用词语多于各区域变体。

The experimental result conducted on large-scale corpus indicates that the performance of this algorithm is remarkably higher than other usual lexical tagging algorithms such as hidden markov model. Meanwhile, by introducing the concept of confidence interval, implement an lexical tagger that combines SVM and HMM algorithms, reaching both high performance and efficiency.

针对句法分析的前期任务：词性标注的特点，提出创新的排歧算法，使得其精度和效率都得到非常显著的提高，为实现高精度和高效率的句法分析系统提供良好的基础。

In the dissertation, the coherence of the works will be testified from three aspects: lexical, clausal and message aspects. In lexical aspect, Anderson achieves the coherence of the works by using those lexical devices such as repetition, collocation, general words and so on; in clausal aspect, through using referential devices skillfully, the author succeeds in creating semantic coherence between clauses in which there are no relationships of grammatical structure; As for message aspect, the pattern of thematic progression shows how new information and given information are connected with each other. At the same time, it portrays the trains of the authors thoughts.

本文从词汇、句子层面和信息结构三方面对小说连贯进行了全面的分析：安德森通过对词汇的重复、词汇的搭配、泛指词等词汇手段的巧妙运用，使小说在意义上达到了很强的连贯；在句子层面上，作者通过巧妙的运用各种照应手段，在互相没有语法结构关系的句子之间产生了语义的连贯；在信息结构方面，主位述位推进模式清晰的勾勒出了作者的思路，各句的信息在语义上的衔接也一目了然。

It proposes that the cohesive force between lexical items is determined by their relatedness both in vocabulary and in the text, that the cohesive scope of lexical items is usually larger than that of grammatical items,and that,so far as lexical cohesion is concerned, all forms of a lexeme have the same cohesive value as the base word.

指出：词项之间的衔接力是由它们在意义上和篇章中的接近程度决定的；就衔接范围而言，词汇衔接手段比语法衔接手段大；在词汇衔接中，同一词根的派生词衔接作用基本相同。词汇衔接关系是篇章构成的重要一环，它往往反映出篇章语义层上的事件线和参与者线，同时也揭示出篇章的主题。
