The experimental system extract the low-level features of images such as HSV histogram, the texture got from coexistence matrix, color correlogram, and according to the characteristic of our image database, design the evaluation function such as the average rank ratio to evaluate and compare the performance of different integration of different features including semantic, and validate the active effect of feedback using experiment results.

In this paper,a design method of two dimensional Linear Phase Nearly Perfect Reconstruction filter banks based on a new class of cosine modulation systems is presented,which can be described as follow: firstly,the Parks-McClellan algorithm is adopted for designing the prototype filter,then by employing cosine modulation,a series of analysis and synthesis filters can be obtained,accordingly a one-dimensional LP-NPR filter banks can be constructed;Secondly,cascading two one-dimensional LP-NPR filter banks in the form of tree structure and using the unimodular transformation,a two dimensional nonseparable LP-NPR filter banks can be obtained.

Chapter 2 strives to gain a clear idea of the prototype of the rural administration system before the transformation by way of reviewing the evolution of configuration and operation of rural public power from the Qin Dynasty to the disintegration of the People's Commune, comparing the three academic theories about the operation of our traditional rural country:"Country gentleman society","State community first society" and "Culture nexus of power".

第二章，追溯自秦汉确立乡制到人民公社解体这一历史长河中，乡村公共权力配置和运作模式的演变过程，比较学术界关于我国传统乡村公共权力运作的三种理论模式，即"乡绅社会"模式、"大共同体本位"模式及"文化网络"模式，力图弄清转型期以前的乡村管理体制原型，并根据"路径依赖"理论分析传统乡村公共权力运作模式对当代农村公共权力运作的影响。

All experienced craftspeople and engineers create prototypes of their work before they build anything: Architects create models out of paper or cardboard, or with virtual reality tools.

有经验的工匠和工程师在他们真正创建之前会创建作品的原型：建筑师用纸或纸板或用虚拟现实工具创建模型。

This article focuses on the line-line, line-region and region-region topological relations algorithm, which come down to the same question: whether there are intersections between line and line. The sweep-line algorithm was studied by many people, but has some deficiencies to be improved, in order to handle some special cases and increase program efficiency. My works as follows: rectangular envelope to reduce executive times , vector cross multiplication to determine intersection between line and line, coordinates and slope method to deal with some special cases. C program examples are showed together.(5) Finally, to prove capability and efficiency of the model and calculation method, some test systems are developed. For example, complex spatial topological relation query, parcels' exact area with the area of linear object reduced in land use, quality inspection to cadastral data according to topological rule, spatio-temporal change query of cadastral data.
