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。

First, based on all that have been mentioned above, the geometric constant D, which was introduced to characterize the quantitative difference between Birkhoff orthogonality and isosceles orthogonality, is studied further. Moreover, attainability as well as continuity and monotony of D in two-dimensional sequence spaces are presented.

Common uses for sets are fast membership testing, removing duplicates from a sequence, and computing mathematical operations such as intersection, union, difference, and symmetric difference.

集合的常用场合是快速测试某元素是否在集合中，或者是从一个有序类型中删除重复元素，或者是做一些数学运算，比如求集合的交集、并集、差和对称差。

The research aimed to seek the difference on rDNA-ITS sequence between Focr 1 and Focr 4 biological races of banana fusarium wilt and provide basis for rapid detection of banana difference wilt race.

寻找香蕉枯萎镰刀菌1号生理小种和4号生理小种(Focr 4)在rDNA-ITS区段序列上的差异，为香蕉枯萎镰刀菌小种的快速检测提供依据。

There was significant difference in signal intensity between the cell concentration group and unlabelled cell group during 2 weeks. And significant difference occurred in the 5×105 SPIO-labeled cells per milliliter medium group and unlabelled cell group during 3 weeks.3. In kidneys of ischemia-reperfusion injury,the labeled BMSCs were demonstrated as signal intensity loss in renal medulla on T2*WI sequence in days 1,3,and5.The signal intensity loss was visualized up to 8 days after transplantation,and the signal intensity in the third day was the lowest. Histological analyses showed that most Prussian blue staining-positive cells were well correlated with the area where a signal intensity loss was observed in MRI.
