本文通过对法律文件语篇的元功能、语境及其组成成分的分析，展示了语篇中语义层的三个元功能与语境的三个要素的密切关系以及法律文件这种正式语体在数量和频率上突出的文体特征，表明了语体的文体特征来自于语言使用者对语言功能和语境的网络系统的选择。

Cognitive context is a psychological construct which differs from the traditional concept of context, and its particularity lies in its strong constructiveness.

认知语境有别于传统的语境概念，它是一个心理建构体，其与传统语境概念最大的差异就在于它具有很强的建构性。

At first, we develop Context-Free Language XMLization system. We use Context-Free Language to describe idea and logic of human, and try to transform it into XML automatically.

首先，我们开发出一个上下文无关语言的XML化系统，利用上下文无关语言来表达人的想法与逻辑，然后透过自动化的转换流程，将上下文无关语言转换成XML。

To satisfy such social needs, English grammar teaching should shift from tradition, which regards grammar as an isolated, context-free and sentence-based language system, to present-day grammar teaching, which matches form with meaning and function in context, with the expectation of helping learners to achieve their ultimate goal, i.e. to use language appropriately, accurately and fluently in real communication.

为培养这样的人才，英语专业的语法教学应摆脱传统教学法的束缚，把语法与意义和功能结合起来，在一定的语境中去探讨学习语法，以期培养学生的交际能力，达到最终的目标，利用语言在实际的语境下自由、恰当、准确地表达思想，而语境语法教学可能成为实现这一目标的有意尝试。

Based on recursive functions defined on context-free language, LFC (language for context free recursive function) is a formal specification language and fits for dealing with phrase structure.

以上下文无关语言上的递归函数为基础的语言LFC(1anguage for context free recursive function)是一种形式规约语言，适于处理短语结构。

Then a new way was defined to prove that the unique set of sequences equivalent to context-free languages can be obtained by mixed self-assembly of mole-cules with 1-,2-,3- sticky ends,which is a supplement for Winfree's theory that the self-assem-bly of dendrimer nanostructures is equivalent to context-free language.

另一方面，文中定义了一种新的通过上下文无关语言通过自装配产生线性语言的方法，即证明了等价于上下文无关语言的特定序列集能通过1-，2-，3-粘头分子的混合自装配产生线性语言，同时，这是对Winfree关于树状纳米结构自装配等价于上下文无关语言理论的一个较好的补充。

In this thesis, I summarize and implement the up-to-date language models, such as N-Gram Language Model, Interpolation N-gram Language Model, Context-Free Grammar and Probabilistic Context-Free Grammar, and establish the run-length language model Character-level and word-level run-length language model are established on the base of the concept of limit entropy and discrete stable information source and by using maximum likelihood between character strings.

在充分研究和比较了中文和西文特点的基础上，提出了变长汉语语言模型。应用极限熵、离散平稳信源和字符串之间的最大似然度等概念和方法，建立了字一级的变长语言模型和词一级的变长语言模型。实验的结果显示这种语言模型不仅比Bigram具有更低的复杂度，而且包含了更长距离内的信息，运行时间也大大小于N-Gram。
