以下賦值語句將產生一個編譯錯誤,原因是賦值運算符右側的算術表達式默認情況下計算結果為On the base of analysis of hydrologic geology from aquifer distribution, boundary conditions and dynamic characters etc. in the research area, the paper sums up the hydrologic geologic condition, builds up the conceptual model of groundwater resource evaluation and presents 2d calculation model, as well as numeric solution and computing flow chart. after introducing general solutions of mathematic models and implementation method of rectangular grid, the paper realizes the automatic technique of spatial dispersion rectangular grid of evaluation models based on gis. finally, the paper fulfills the integration of gis with groundwater resource evaluation models from gis - based basic management information, spatio - temporal dispersion of models, definition of subprogram and visual evaluation of parameters, as well as models simulation etc., and visualizes the results of evaluation models
論文以地下水超采?地下水降落漏斗?地面沉降現象較為嚴重的常州、武進地區作為研究評價區域,在對評價區域的含水層分佈、邊界條件和動態特徵等水文地質條件分析的基礎上,概化了其水文地質條件,構建了相應的地下水資源評價概念模型與數學模型,並給出其數值解法和相應的計算流程;論文在介紹數學模型的兩種常用數值解法和模型空間離散的矩形網格生成技術的基礎上,實現了基於gis的評價模型空間離散矩形網格的自動生成;最後,論文從基於gis的評價模型基本信息管理、模型空間時間離散方法、子程序包與模型計算參數可視化賦值、模型的擬合等方面實現了gis與評價區域的地下水資源評價模型的集成,並將模型評價結果可視化。Arithmetic assignment statement
算術賦值語句The algorithm is a new multi - objective optimization evolutionary algorithm using elitism, in which fine - grained fitness assignment strategy, a density estimation technique, and an enhanced archive truncation method are used. the algorithm can converge to the pareto optimal solutions rapidly and the non - dominated solutions gain better distribution and spread
Spea2演算法是一種新的使用了精英機制的多目標優化演化演算法,它採用了細粒度賦值策略和密度估計技術,整個演算法可以快速收斂到pareto最優解,並且可以獲得很好的分佈性和延展性。Performs an arithmetic right shift on the value of a variable or property and assigns the result back to the variable or property
對變量或屬性值執行算術右移位,並將結果賦回給該變量或屬性。In the thesis, i choose the horizontal and symbiotic industrial cluster basing on the natural resources as the objects to study, and make full use of knowledges from many subjects, including : economy, management, complex science, math, computing simulation, etc. through the idea of " down to up ", i make every individuality ( company ) inside the industrial clusters as a cell ; and choose techological support, labor supply, natural resourses reserve, maket overlay, intermediary service, public foundation, govenment policies as the outside influencing features ; and choose total assets, total production value, output ratio of capital as the indexes of system characters. then, i establish a computing simulation model on the optimal scale of industrial clusters basing on cellular automata model by matlab software, and simulate the shifts of characters of sigle cell according to the changing environments
本文主要以基於自然資源稟賦的水平共生型產業集群為研究對象,綜合應用現代經濟學、管理學、復雜性科學、數學和計算機模擬方法等多學科的知識,吸納「自下而上」的思想,選取技術支撐、勞動力供給、自然資源、市場輻射、中介服務、公共基礎、政府政策七個變量作為集群成長的外部影響因素以及總資產、總產值和資金產出率作為集群的系統特徵指標,以產業集群(系統)內部的個體企業為單位元胞,參照自適應、自組織的自然演化機制模擬單位元胞自身特質受到周邊環境的變化而改變,採用元胞自動機模型和matlab軟體,建立一個基於元胞自動機模型的產業集群規模演化的計算機模擬模型。分享友人
