Museum's permanent exhibition -"simulated mine", its scale and rich in content, similar museums in the world is rare, he brought together the scientific, intellectual, interesting as one, the application of high and new technology and the arts each other The combination of modern means to create a display of real-borne Lane, the ancient manual mining, modern coal mining and blasting hole heading face, modern mechanized mining and geological structure as well as the heading face eight landscape.

博物馆永久的陈列——《模拟矿井》，其规模之大，内容之丰富，在世界同类博物馆中是少见的，他集合了科学性，知识性，趣味性为一体，应用了高新技术和艺术相互结合的现代展示手段来营造出逼真的媒巷，古代手工采煤，近代打眼放炮采煤和掘进工作面，现代综合机械化采煤和掘进工作面以及地质构造等八个景观。

Ning Xi, Nanshui, the deep well of the Hengqin Island, two wells, the Jin River Po in the first, and other places to stay Shishan weathered rock vein type kaolin mine has a value of the mining industry; gate six under, in, Yongfeng, Kwun Tong, the former Dongkeng Hill, Doumen's Lek Qi, Masan, and so on up to the foothills of the clay-alluvial mining for small-scale mining.

柠溪、南水、横琴岛的深井、二井、金鼎的河头埔、留狮山等地的风化岩脉型高岭土矿具有一定的工业开采价值；下栅六组、会同、永丰、官塘，前山的东坑，斗门的岐沥、马山、大托等地的山麓冲积型粘土矿可供小规模开采。

That is that information processing of neural networks is viewed as the composition of the two steps: field organization and field action, in which, field organization transformation converts input pattern into relevant structure representation, extracting the underlying architecture features and forms a architecture representation in action transformation space; The field action transformation converts the features representation into expected output. In strategies, we use the dual affine coordinates in dual flat manifold as way of representation of field organization system and field action system, which established a theoretical framework of analysis the coupling mechanism of information processing from the view of point of structure representation and model generation.

在具体人工神经网络结构描述的策略上，利用对偶流形空间上的对偶仿射坐标概念分别表示场组织变换系统和场反应变换系统，建立起从问题的结构表示和模型生成两种观点来分析信息处理的理论框架；分析了有监督和非监督学习人工神经网络模型在神经场变换机理下的形式化描述。

Furthermore, as stresses in the stress field influence the value of seepage coefficient k, which will results in the change of seepage field in the end, while on the other hand, the seepage field also has an effect on the stress field because of seepage forces. Based on the coupling model of seepage field and stress field, a program by finite element method is developed in this paper. And the comparison of results of the program and criterion method with that of test shows that the test results are reasonable, which can be referred to analyze the causes of dangers, evaluate degree of safety of the body and foundation, and design and optimize the measures of seepage control.

此外，考虑到应力场中的应力会改变土体渗透系数进而影响渗流场、而渗流场也因其产生的渗透力会导致应力场发生变化，两者之间存在耦合作用，本文基于渗流场应力场耦合分析的数学模型编制了渗流计算有限元程序CCOSAS1.0，其计算结果和采用规范方法所获得的解答与实测值的对比分析表明，该规律合理且具有一定的代表性，可用以分析险情发生原因、评价堤身堤基安全状况及设计与优化渗流控制措施。
