Increasing the calcining temperature at 1500℃ 5h, the morphologies of the product became the big and wide vermiform-fiber form particles, the length was about 2.5 μm, and the width was about 700 nm. In addition, the vermiform-fiber form particle could be found in the filtrated precipitate with the additional ammonium sulfate. If the ratio of ammonium sulfate to alum is above 1, the vermiform-fiber form particle was formed. After calcined at 1500℃ 5h, the particle grow up to 2μm. Adding ammonium sulfate was also reduced the particles size of alumina because the surface area of the products was increased by increasing the quantity of ammonium sulfate.

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。

The research contents mainly include: First, the influence of foundation constraint condition to the temperature stress is analyzed, the temperature stress formula of ultra-long concrete anchor plate is deduced, then the influence of length to structure crack can be gotten from the formula. Second, a breathing method is set up to solve the problem of temperature stress in ultra-long concrete constructions. By setting the sliding floor, a breathing system is built up and the temperature stress reduced distinctly. Third, the effect of prestress technique in the control of temperature stress is analyzed, it is simulated and calculated through FEA to get the right way to apply the prestress. Forth, the delay of temperature field and unsteady conduction is considered, the temperature field of ultra-long concrete structure with later poured band is simulated, then temperature stress distribution after casting the concrete is calculated, finally the effect of later poured band to temperature stress of ultra-long structure is analyzed.
