Fe*WJ,k.Q0【英文摘要】 Abstract: Component Object Model is a component-based development model, which leads a revolution in the fields of software development. Now, this model is used for the numerical model in the field of Coastal Engineering, and an integrated numerical model system is completed. According to the theory and characteristic of COM Technology, an integrated system is set up, where the computing component of numerical model is the core object, and GIS system ------MapObjects is used as a visualization environment, and a relational database is used to manage data. Two more functional objects are included in the system: One is the coordinate conversion component, the other is ADO based database interface component. The integrated system is applied to simulate the tidal current movement at the South of Hangzhou Bay, which shows that the system and its components are simple and convenient to use, reuse and set up. The COM GIS system ESRI MapObjects is stable and good to be assembled in an integrat...更多ed system for small or medium size. When the computing component of numerical model is setup, object-oriented programming theories have been fully utilized, such as classes, objects, pointers, dynamic arrays, multi-thread technology etc., which have greatly increased the computing speed of the computing component of numerical model.  还原水利论文'I;S.\,I fr
