輸出布線區
英文
oroutput routing pool-
The algorithm has many advantages such as the input format and output format being uniformed, high efficient, wide application, etc. it has abroad market values in many domains, such as the weather character demonstration, computing and the demonstration of anomalous graphics, etc. we know that curves can be approached by mini line - segments, so the boolean operations between almost all regions can be implemented by this algorithm
本演算法具有輸入、輸出數據格式統一、效率高、應用面廣等優點。在實現天氣氣象圖的演示、各種不規則圖形的顯示和計算等領域具有很廣闊的市場前景。由於曲線邊界可以由小線段組成的多邊形來逼近，所以通過本演算法，我們還可以實現任何邊界區域間的布爾操作。Aimed at the current problem of pipeline layout optimization technique, the research of irrigation pipeline layout and pipe diameter optimization has been done, the gis ( geography information system ) and graph theory were first put forwarded to applyed to the design of low pressure pipeline irrigation project in the paper. with the support of gis, the minimal spanning tree theory of graph theory and 120 project theory can be applied to irrigation pipeline ' s layout optimization. at the aspect of pipe diameter optimization, simplicial method and interior - point method are been used in solve liner optimization model of pipe diameter to reach minimum project cost or a nnual working cost of low pressure pipeline irrigation
本文主要針對當前南方地區低壓管道輸水灌溉規劃設計中存在的技術難點，開發研究先進實用的樹狀低壓輸水灌溉管網計算機輔助設計系統。首次提出了將gis （地理信息系統）和圖論技術應用於低壓管道輸水灌溉規劃設計及灌溉管網優化中，在gis支持環境下，應用圖論中的最小生成樹法和120規劃進行管道的最優化布置。建立以管道輸水灌溉系統的年折算費用最小為目標函數的管徑優化線性規劃模型，並將內點法應用於線性優化模型的求解。With an analysis of the characteristics of beijing, the condition of its population distribution, and an exposure of the contradictions between road structure and modern traffic means, the author argues that urban roads ( railway lines ) shall be constructed ahead of districts ( blocks ), and light rail transport shall be given more attention to than metro development, and finally suggests that the structure of transport shall be optimized, including the construction of passenger terminals and fast suburban railways, so as to meet the needs of a modern city
摘要分析了北京市的城市特點及人口分布現狀；指出了目前北京市道路結構的問題及其與現代化交通之間的矛盾；提出了要先建「線（路） 」后建「區」 ，在發展地鐵的同時重視發展輕軌運輸，按現代化城市要求優化道路結構，建設客運樞紐，發展市郊快速鐵路等建議。The paper made a brief introduction to present application status of pas and brought up the idea of researching on pas based on transmission over low - voltage power distribution networks. new pas possesses advantages such as avoiding wiring, convenient maintenance, flexible area - dividing mode and readily expanding
文章首先對目前pas的應用現狀進行了簡單介紹，提出基於低壓配電網傳輸的pas的研究設想，新的pas具有免布線、維護方便、分區靈活和易於擴展等優點。分享友人
