派生

All Expression classes are derived from the abstract base class Expression.

With respect to syntax, the roles of tagmeme in the structure of word and sentence and Chomsky's Generative-Transformational Grammar are discussed. The spatial relation theory and existing research achievements are investigated. Having noticed the shortage of the capability of topological and metrical relation in the description of spatial information structure, the author proposes Combinational Qualitative Geometry based on the two invariables under ordinary transformations, distance ratio and direction difference, the CQG-based spatial relation system between topological and metrical constraint is thus constructed, on which several spatial relations such as parallel, perpendicularity, co-linearity, sequence and direct neighborhood are derived. Based on extended theory of spatial relation, the language anamorphosis is analyzed from the aspects of phonetics, semantics and syntax. The mere geometric and formalized spatial relation is then integrated with concrete geographic ontology to accommodate richer and indicative spatial configuration of spatial information in the different geographic context. Finally a syntax framework for spatial information is put forward.

在语法结构方面，首先阐述了法位和法素在语法结构词法和句法中的地位和作用，以及Chomsky生成转换语法的核心内容；详细介绍了地理信息系统空间关系理论及现有的研究成果；在分析现有的拓扑关系和量度关系对空间信息结构描述能力不足的基础上，提出了基于长度比和角度差两个不变量的组合定性几何，以此建立了介于拓扑及量度约束之间的组合定性关系体系，并以此为基础派生出平行、垂直、共线、次序、直接邻近等空间关系描述；本文基于扩展的空间关系理论，详细讨论了空间关系在语音、语法和语义三个方面的语言变体，将纯几何和纯形式化的空间关系与具体的地理本体结合起来，可以获得更为丰富的、更能反映空间关系在不同语言上下文中具体体现的组合关系；最后给出了一个空间信息的语法结构的基本框架。

According to present research status at home and abroad, the inversion problems of structure is resolved so successful in the region of pull-apart structure, there have many theory model, whereas, some special cases should be discussed, for example synthetic and antithetic faults form during rollover deformation in the hanging wall, these subsidiary faults share part of the cumulative extension in a listric fault system and may influence predictions of the major fault geometry.

从目前国内外在构造反演这一问题的研究现状来看，在拉张构造区域，反演问题在理论上有比较多的模拟解决办法，并且应用的相当成功，不过考虑到有些特殊的情况，比如逆牵引构造所派生的次级断裂会造成反演计算结果的不准确，因此对现存的反演模型稍微做出了点修改，使之更能广泛的应用于实际的构造解释。
