  1. According to the process of developing cppm - gis, this paper introduces the systems analysis, requirement analysis and the function design of every module in order. then realization of every module is explained correspondingly

    本文根據gis系統軟體的開發過程按順序介紹了cppm - gis的系統分析、需求分析及各模塊的功能設計，然後對應說明了各模塊的程序實現。
  2. Chaotic switching modulation signals generated from different chaos sequences have been used to control smps. the effect of reducing the level of emi be compared. simulation results demonstrate : in the cpwm and cppm, chaos sequences generated from henon map is superior to the one generated from chua ' s circuit at lower multiples of switching frequency on reducing the level of emi ; in the ccfmfd, it has contrary results ; in the ccfmvd, chaos sequences generated from chua ' s circuit is superior to the one generated from henon map

    模擬結果表明： cpwm和cppm模式下， henon映射混沌序列在較低次諧波處降低emi水平的效果要好於蔡氏電路混沌序列的效果。 ccfmfd模式則有相反的結果。對ccfmvd模式，蔡氏電路混沌序列比henon映射混沌序列降低emi水平的效果明顯要好。
  3. As a important component in cppm - gis, this paper illustrates detailedly the mathematics model of optimum design and direct optimization method for drainage pipe - net under gis. as a key stage in planning and designing the drainage system, the caculation of pipe - net is very critical and time - consuming. this paper brings forward the recursive arithmetic for pipe - net and pipeline designed - discharge

    在cppm - gis系統中，水力計算模塊是一個重要的組成部分。本文詳細論述了gis環境下建立排水管網優化設計的數學模型、排水管網的直接優化法。
  4. City pipe - net plan and management under gis ( cppm - gis ) is a application integrating maplnfo map windows into visual basic program using mapbasic and visual basic. in this system, the spatial data and attribute data of drainage pipe - net are storaged separately in maplnfo tables and access database. they can be linked by program and provide some special function

    城市排水管網規劃及管理gis系統cppm - gis是利用mapinfo的二次開發工具mapbasic和visualbasic語言將mapinfo地圖窗口集成到vb程序中而開發出來的應用程序。在該系統中，排水管網的空間數據與屬性數據分別存儲于mapinfo表和access數據庫中，編寫程序將兩者連接起來並實現一定的功能。
  5. Chaotic switching modulations generated from different chaos sequences introduce low - frequency output noise ripple : in the cpwm, cppm and ccfmvd, the output noise ripple introduced by henon map chaos sequences is smaller than chua ' s circuit chaos sequences ; in the ccfmfd, chua ' s circuit chaos sequences introduced smaller noise ripple. this clue to us that it is important to choose chaos sequences in applying chaotic modulation to dc / dc converters

    不同混沌調制信號對輸出紋波影響的分析結果表明： cppm 、 cpwm和ccfmvd模式下， henon映射混沌序列引入低頻噪聲紋波比蔡氏電路摘要混沌序列要小; ccfmfd模式下，蔡氏電路混沌序列引入的低頻紋波要小。這提示我們:在開關模式電源使用混沌調制控制時混沌序列的選擇也具有重要性。
