  1. The attainment proves that the method is prompter than the conventional ones and reduces the amount of work greatly. moreover, when the db is connected with regional information system of transfered, it is possible to study the changing characterises or regional land use through quantity change, furthemore, to find out the decipline and the dynamic changes of spatial distribution of type of land use through land use maps

    結果表明與傳統調查方法相比速度快,工作量大大減少,且把數據庫與區域信息系統連接或被調用,不僅可以通過數值的變化,研究區域土地利用狀況的變化特徵,還可以從圖形上體現出土地利用類型的空間分佈規律,以及空間分佈的動態變化情況。
  2. 1. 4 based on the attribute db, the soil classification graphic db is set up by using arc / info cis. the soil order, suborder sketchs and basic classification unit ( series ) sample maps, make the distribution of soil in hubei province clear at a glance

    4在屬性數據庫的基礎上,利用arc infogis建立了湖北省土壤分類圖形數據庫(空間數據庫) ,運用計算機編制和輸出了全省土壤系統分類土綱、亞綱概圖和基層分類單元(土系)樣塊圖,使全省土壤分佈狀況一目了然。
  3. The data balance distribution of parallel db based on the network system

  4. In addition, it puts forward a nested temporal db, which, with stronger expressive ability than others, is a breakthrough to entity - relationship model and is referred to as nter model. it also verifies the expressive ability of nter when it is applied to sidss. finally, in view of the features of sidss and the current status of salary distribution system, it conducts initial study of the sidss based on temporal - spatial relationship and the sidss with a temporally - driven knowledge database, with the aim for us to develop a consummate sidss system in the future

    本文中,介紹了時態數據庫的基本概念、發展、特點和分類;結合sidss的背景、特色及體系結構,詳細討論了sidss的時態性及其數學模型,指出將時態數據庫應用到sidss並作進一步的研究是必然趨勢,並在此基礎上研究了時態數據庫系統的模型;在探討了幾種模型之後,打破實體-關系類的模型的框框,提出了一個表達能力較強的嵌套時態數據模型,稱之為nter模型( nestedtemporalentity - relationshipmodel ) ,並驗證將其應用到sidss系統中的表達能力;最後針對sidss的特點以及目前工資管理系統的狀況,進一步對基於時空關系的sidss系統、由時態驅動知識庫的sidss系統進行初步探討,以期今後對開發更完善的引) ss系統作進一步的研究。
  5. The analytic result derived by studying the vertical directional property shows that, the vertical sensitivity distribution is homogeneous and the fluctuation is 0 db in theory. the fluctuation observed in experiments is less than 0. 3db, which agrees well with that in theory

    垂直指向性分析結果表明,光纖水聽器垂直方向的靈敏度分佈是均勻的,理論上波動應為0db ,而實驗測得的垂直方向的指向性波動小於0
