- 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
本文根据gis系统软件的开发过程按顺序介绍了cppm - gis的系统分析、需求分析及各模块的功能设计，然后对应说明了各模块的程序实现。 - 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
仿真结果表明： cpwm和cppm模式下， henon映射混沌序列在较低次谐波处降低emi水平的效果要好于蔡氏电路混沌序列的效果。 ccfmfd模式则有相反的结果。对ccfmvd模式，蔡氏电路混沌序列比henon映射混沌序列降低emi水平的效果明显要好。 - 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系统中，水力计算模块是一个重要的组成部分。本文详细论述了gis环境下建立排水管网优化设计的数学模型、排水管网的直接优化法。 - 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
城市排水管网规划及管理gis系统cppm - gis是利用mapinfo的二次开发工具mapbasic和visualbasic语言将mapinfo地图窗口集成到vb程序中而开发出来的应用程序。在该系统中，排水管网的空间数据与属性数据分别存储于mapinfo表和access数据库中，编写程序将两者连接起来并实现一定的功能。 - 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
不同混沌调制信号对输出纹波影响的分析结果表明： cppm 、 cpwm和ccfmvd模式下， henon映射混沌序列引入低频噪声纹波比蔡氏电路摘要混沌序列要小; ccfmfd模式下，蔡氏电路混沌序列引入的低频纹波要小。这提示我们:在开关模式电源使用混沌调制控制时混沌序列的选择也具有重要性。
