After analyzing the merit and lack of 9I model, the main idea is proposed: to distill some basic topological relations from 9I model, of which the composite topological relations of complex objects are made up. In detail, the composite topological relationships between region and region, line and line, line and region are particularly discussed;(2)Analyze the characteristics and inner relations of cadastral features. According to the expressional model of complex topological relations, the author discovers the possible topological relations between parcels, parcel lines and parcel points. In addition, sum up the general topological relationship rules of cadastral data.(3) Then the topological relations model is extended to the spatio-temporal data. Time in cadastral database and change semantic are discussed. It's redefined that spatio-temporal topological relations is composed of time, location, status and event relation. Spatio-temporal topological relationships can be represented by extended 4I model. Taking cadastral parcels as example, there are different possible spatio-temporal topological relationships between parcels when they are extended, shrunken, split, merged or others. Thus, some deductions are drawn that, for example, if parcels have be coexisting for some time they are impossible to be overlapped. Furthermore, the parents of parcels alternated and their possible change types can be detected by their spatio-temporal topological relationships.(4) Before carrying out the experiment, the calculation method must be designed.

The formation of secondary phase in the non-equilibrium peritectic reaction was observed by precise transmission electron microscopy analysis. The microstructural evolution and phase selection regularities under different solidification velocities were constructed from the laser resolidification experiments. A new phenomenon involving two-phase coupled growth was firstly detected in the rapidly solidified Ti-Al peritectic alloy. The Ti-45Al-2Cr-2Nb alloy with fully lamellar structure ( a 2+ g ) was taken as an object to investigate the possible preparation of bulky metastable g phase materials based on both adjusting the competing nucleation relation and changing the growth kinetics condition.
