The efficiency and reliability of minerogenetic prediction can be improved by combining rs with gis. we processed rs images, extracted the geological information related to mineralizing, such as geology, structures, stratam, rocks, etc, synthetically analysed remote sensing, the geological data and geo - chemistry, under the guidance of the theory and mathematic model, set up gis mineralize model. on this condition, to develop this method and its theory, and to establish a system of perfect prediction, it is not only useful in studied degree area but also favorable for looking for new type and some form large - scale deposits in old studied area, and it has a great theoretical meaning
遙感與gis相結合用於成礦預測中可大大提高預測工作的效率和可靠性。通過對研究區的遙感圖像處理和地質、構造、地層、巖石、礦化蝕變等有關信息的特徵提取、遙感、地質數據和物化探數據的綜合與復合分析,在一定成礦理論和數學模型指導下,建立gis綜合找礦模型。在此基礎上,發展這一方法及理論並建立完善的預測體系,不僅對研究程度較低的新區礦床預測有用,而且對研究程度較高的老區尋找新類型和點狀大型、超大型礦床都具有重要理論意義和實際意義。A fuzzy image data model and a concept of fuzzy space are proposed, in which model visual feature, spatial feature and semantic feature are used for super feature in order to utilize advantage of traditional relation database as well as characteristics of image data and fuzzy retrieval. based fuzzy space, a method of similarity measurement of image is presented to support fuzzy features - based image retrieval and satisfy user ' s query requirement for image. in the thesis, a semantic template and the mechanism of dynamic relevant feedback are defined so that it can express user ' s query semantic and improve retrieval precision and useable capability for image retrieval
研究了模糊檢索方法和相關反饋機制在圖象檢索中的應用,提出了一種模糊圖象數據模型和模糊空間的概念,該模型將可視特徵、空間特徵、語義特徵看作超屬性,既充分利用了傳統關系數據庫的優點,同時又考慮了圖象數據以及模糊查詢的特點,文中提出的模糊空間和模糊相似性度量方法能支持基於模糊特徵的圖象查詢,較好地體現用戶圖象查詢的應用需求,文中定義的語義模板和相關反饋機制能在一定程度上表達用戶的查詢語義,提高圖象檢索的準確率和易用性。Research result shows that the object - oriented geographic spatial model has stronger representative ability, is easier understood and accepted ; using the concept of geometric data type unify the process method of attribute and spatial data, and simplify entity query and analyses. the topologic relations between entities, which are not been stored in explicit formulation in the model, can be achieved through collective operation of geometric object ' s hypergraph model. compared with traditional his, the query and analyses ability of which based on new model are stronger
研究結果表明,面向對象的地理空間模型具有更強的表現能力,並且容易被理解和接受;採用幾何數據類型的概念,可以使對非空間數據和空間數據的處理方法相統一,而且會使對實體的各種屬性數據(包括空間屬性)的查詢和分析模型更加簡單;對于面向對象模型中不顯式表示的地理實體間的空間拓撲關系,可以利用實體的幾何對象的超圖模型間的集合運算來求得;基於面向對象地理空間模型的實體查詢和分析,也比基於傳統gis數據庫查詢和分析具有強得多的功能。As far as model is concerned, the forth generation software should be characterized with spatial entity - oriented. the paper established the geographic spatial model based on the thinking of object - oriented ; studied the structure of the model " s elementary unit - - geographic entity ; brought forward the concept of geometric data type which characterize entity ' s spatial feature in the structure ; defined five kinds of geometric data types such as point, arc, area, composite arc, composite area ; and formalized their collective operation using hypergraph. at the end of this paper writer studied preliminarily the method of entity query and analysis based on the model
本論文從面向對象的基本思想出發,建立了面向對象的地理空間模型;研究了地理空間模型中的基本單位? ?地理實體的結構,針對實體結構中用來表徵實體空間特性的組成部分? ?幾何對象,提出了其取值范圍,即幾何數據類型的概念;對點、弧、面、復合弧和組合面五種幾何數據類型進行了定義;並使用超圖工具對幾何數據類型的集合操作進行了形式化描述;對基於面向對象的地理空間模型的實體查詢和分析方法也做了初步研究。Following the development trend of valve cad, according to the requirements of the chengdu chengfeng valve limited company and based on mdt, this article develops the 3d parametric valve design system. the main work and achievements are as follows : based on the 2d engineering drawing of the several different valves the company provided, the 3d parametric basic drawing - base is set up using mdt which is a 3d design platform, including all the parts drawings and the general assemblage drawings of the valve models ; in accordance with the common steps of the valve design, the parameter editors are designed to edit, import and export the valve parameters and are provided with the function of double synchronization on parameters displaying for convenience in use ; in order to meet demands of users and make the design more accurate, reliable and practical, the assistant formula calculators are developed, which can automatically do all types of structure calculation in the procedure of valve design, and export the calculation manual of valve design ; in order to make designers more rivalries, taking full advantage of internetmntranet technology, the virtual design center is developed, which integrate netmeeting, terminal service and super links, so that the designer can directl y use applications on remote server, communicate with other designers on intranet / internet, share software resources and realize long - distance cooperative design
