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(jù)gis系統(tǒng)軟件的開發(fā)過程按順序介紹了cppm - gis的系統(tǒng)分析、需求分析及各模塊的功能設計，然后對應說明了各模塊的程序?qū)崿F(xiàn)。
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
仿真結(jié)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水平的效果要好于蔡氏電路混沌序列的效果。 ccfmfd模式則有相反的結(jié)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。
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(tǒng)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(huán)境下建立排水管網(wǎng)優(yōu)化設計的數(shù)學模型、排水管網(wǎng)的直接優(yōu)化法。
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(wǎng)規(guī)劃及管理gis系統(tǒng)cppm - gis是利用mapinfo的二次開發(fā)工具mapbasic和visualbasic語言將mapinfo地圖窗口集成到vb程序中而開發(fā)出來的應用程序。在該系統(tǒng)中，排水管網(wǎng)的空間數(shù)據(jù)與屬性數(shù)據(jù)分別存儲于mapinfo表和access數(shù)據(jù)庫中，編寫程序?qū)烧哌B接起來并實現(xiàn)一定的功能。
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(diào)制信號對輸出紋波影響的分析結(jié)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(guān)模式電源使用混沌調(diào)制控制時混沌序列的選擇也具有重要性。
