This paper aims at the prominent issue that current models of spatial topological relations can not represent complex object, among which 9-Intersections Model (9IM) is well known. Therefore, taking cadastral data as example, one model of topological relations between complex and spatio-temporal objects based on 9IM is put forward. And the improved sweep-line algorithm is designed. Specific studies as follows:(1)According to the concepts of point set topology, the author distinguishes the complexity of the object, redefines the spatial point, line and region. For instance, in the simple region, concave one is more complex than convex, composite regions can be composed of many parts or with holes, and so on.

本文针对当前空间拓扑关系模型无法表达复杂对象的突出问题，以地籍对象为实例，以9I模型为基础，探索了一种适合复杂对象和时空对象的拓扑关系表达模型，较好地解决了地籍对象中各类要素间拓扑关系的描述和应用，实现了地籍变更中变化语义类型的推理和历史回溯；通过对现有的拓扑关系计算方法进行了改进，设计了相关算法，给出了C语言程序示例；最后通过实验系统的实现，验证了模型和算法的可行性。

Each of those entities developing a mind/body/spirit complex, and then developing a social memory complex, and then dedicating this social memory complex to the singular service to the one Creator, may join the confederation.

As metal ions can interact with both of ADM and DNA, they undoubtedly affect the interaction between ADM and DNA. Addition of a large excess of Cu or Fe into a solution of well-formed ADM-DNA complex makes the metal ions simultaneously bind to ADM and DNA to form a ternary complex. Otherwise,〓 or 〓 complexes can bind directly to DNA to form a ternary complex.

金属离子-ADM-DNA三元体系的光谱研究表明，当ADM与DNA结合后，大量Cu或Fe的加入可以使金属离子进入到ADM-DNA复合物中，并同时与ADM和DNA键合，形成三元复合物；反之，若ADM先与Cu或Fe配位，生成的金属配合物则能够直接与DNA结合形成三元复合物。

So far, studies on complex networks can be divided into two main categories: one is studying the topological properties of complex networks and various mechanisms to determine the topology; the other is studying how their complex connectivity can affect the dynamic features of the system.

论文第一部分中，我们研究了耦合Hodgkin-Huxley神经元模型中外噪声或内噪声与耦合同时存在时体系的动力学，发现了体系尺度共振和双重体系尺度共振现象：存在最佳噪声强度的最佳数目的神经元耦合在一起可以使得体系的集体行为最为有序。

In the same time, water-soluble bidental phosphines ligand BISBIS sulfonated 2,2''-bis(diphenylphosphinomethyl-1,1''-biphenyl was synthesized, and water-soluble rhodium complex Cl was synthesized in situ. This complex which was used as catalysts to catalyze the hydrogenation of avermectin was also tested. Although the rhodium complex containing bidentate phosphine BISBIS showed a higher catalytic activity than one containing TPPDS, the selectivity for ivermectin was lower. How to improve the selectivity will be needed to studied in futur.
