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.

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。

An exceptional condition is a problem that divvents the continuation of the method or scope that you're in. It's important to distinguish an exceptional condition from a normal problem, in which you have enough information in the current context to somehow cope with the difficulty. With an exceptional condition, you cannot continue processing because you don't have the information necessary to deal with the problem in the current context .
