With synthesizing the relevant other internal and external researchers " the achievements of theory and the results of experiment, the follow work have been done in this project : revising the formulas of ground stiffness coefficient and the mass of vibrating soil and the dynamic affecting degree of depth, which apply the theory of elastic half - space and the knowledge of the soil mechanics and consider the influence of the soil characteristic and inertial action, the interaction between foundation and ground, the diverse load ; making the model of ground and foundation system calculating natural frequency by using the big - scale software supersap which is for special purposes of finite element analysis ; according to the experiment analysis, correcting and adjusting the finite element model in order to have it accord with the fact and meet the engineering demands ; doing the vibrating experiment for testing the results of the theoretical analysis and the finite element calculation ; summing up some regulars of the ground stiffness
本文綜合參考了國內外其他學者的理論成果和實驗結果，進行了如下研究工作：運用彈性半空間理論和土力學的知識，考慮土體特性和慣性作用、基礎與地基的相互作用以及不同荷載形式等因素的影響，對動力機器基礎進行了嚴密地理論分析，修正了地基剛度、參振土質量和動力影響深度的計算公式；利用專門用於有限元計算的大型分析軟體supersap對地基基礎體系進行了建模計算，根據實驗分析，對有限元模型不斷地進行修正和調整，使其更加符合實際情況，滿足要求；通過振動實驗對理論分析和有限元計算結果進行了驗證；總結出了一些地基剛度的變化規律。 -
The dissertation, transition economy as background, describes full - scale analysis on constructing chinese natural monopoly industry effective market and put forward the boundary of market and government, market and corporation, monopoly and competition model. the dissertation analyses concealed administration monopoly ’ s character and its hazard, and considers that the most important reason which leads to the chinese natural monopoly industry ’ s short of efficiency is that scale economy is short of character and efficiency, scope economy isn ’ t realized, inefficiency non - regulation equilibrium coexists with regulation equilibrium and the dilemma of state - owned corporation. the dissertation puts forward the vertical configuration principal in the regulation structure and deems that natural monopoly industry ’ s regulation vertical configuration should
論文以轉型經濟為背景，對中國自然壟斷產業有效市場建設進行了較為全面的分析，比較和描述了市場條件下與轉型期存在顯著差別的市場與政府、市場與企業、壟斷與競爭的邊界模型，界定和分析了隱性行政壟斷的特徵及其危害性，認為導致中國自然壟斷產業市場低效的基礎性原因是規模經濟特徵和規模經濟效率的雙重不足，范圍經濟沒有實現，無效率的非均衡規制和均衡規制並存，以及國有企業的困境。 -
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。
