In chapter 4, basing theories and methods of scientific visualization, and artificial neural network BP algorithm, we integrate the Visual C++, OpenGL graphics library and Excel VBA technique to develop the program of artificial neural network and to make the BP algorithm visually, this program works can be divided into four parts: Using C language to develop program about BP algorithm; Using Visual C++, develop the GUI Interface, make input parameter visually; Using OpenGL graphic technique to display the training sample point in three dimension; at last using Excel DDE technique display the error graphic tables in Excel system In chapter 5, on the view of engineering application, we establish new method of surface reconstruction basing artificial neural network, develop interface program between module and commercial CAD/CAM system, meantime deeply discuss some key problems, for example, setting up the base plane, using the API technique, cutting and editing surface boundary, and also discuss the more compliant problem: how to intersect surface, at end we finish the work of translation from our surface reconstruction module to commercial CAD/CAM system, then make reverse engineering system basing artificial neural network more useful.
第四章基于科学计算可视化理论,依据人工神经网络BP算法理论模型,综合Visual C++,OpenGL图形库以及Excel VBA等多项软件开发技术,编制了人工神经网络程序,实现了BP算法的可视化映射。具体工作分为四部分:利用C语言实现人工神经网络BP算法;利用VisualC++的GUI技术开发图形用户界面,实现参数设置可视化;利用OpenGL图形技术进行三维映射,显示学习样本及训练样本点;利用微软电子表格DDE动态数据交换技术,在Excel上动态显示学习误差曲线图。第五章从工程应用的角度出发,提出了一种新的基于人工神经网络算法的曲面裁剪重构方法,完成了曲面重建模块与通用CAD/CAM系统的接口设计工作,对其中的若干关键问题进行了深入讨论,例如基平面设定、API技术的应用、边界裁剪等问题,同时,对曲面计算中较为困难的曲面相交问题也进行的专门探讨,最终完成了曲面重建模块向CAD/CAM系统的数据传输工作,使人工神经网络逆向工程系统趋向实用。

Based on Hutchinson niche and Guangxia Cao\'s definition, Fuzzy hypervolume niche evolves the theory of fuzzy niche: the niche is a fuzzy hypervolume; the niche of the species is a hypervolume with fuzzy boundary which is formed by the n-dimensional resources (time, space, temperature, humid, trophic,...) necessary for the species\' continuous existing and multiplying; membership of a point in the niche is equivalent to the adaptive degree of the species to the point of the environmental resources.
在Hutchinson生态位和Guangxia Cao的定义的基础上,模糊超体积生态位发展了模糊生态位理论:物种的生态位是可以使物种生存和不断繁殖的n维环境变量(时间、空间、温度、湿度、营养……)所形成的边界模糊的一个n维超体积;隶属函数表明n维资源空间的一个点x属于生态位的程度,也表明物种对环境资源的适应程度。
