We also analyze the influence of the boundary condition 、 safety distance and deceleration probability to the traffic flow. finally, we propose an crossroad modle. this model is made up of one main road and one branches : traffic with lights placed on the crossing, vehicles " breaking while running and turning to other direction while jamming. we investigate the velocity and flow of the model when the initial density, the brake and turning probabilities, the green to signal ratio are changed. then the reasons causing all the kinds of phenomena are analyzed
最後研究了周期性邊界條件下的十字路口的ca模型,該模型由一條主幹道和一條支道組成,在幹道與支道的交叉路口設置紅綠燈,車輛在運行中對突發事件發生反應的剎車,路口的車輛可以轉向等各種實際交通行為,並通過計算機模擬,研究模型在改變車輛的初始密度、剎車概率、轉向概率、紅綠燈信號的綠信比等各種情況下支、主幹道車輛的速度、流量的變化,並分析在各種情況下交通狀況的成因,提出改善交通的有效措施。Secondllv in the 1 d random traffic flow model. the relation function between the correlation and the creation. disappearance. brake probabilities of the vehicles is presented. according to the statistical mechanical approach to the spatial correlation functions. the theoretical results agree with that of the computer simulation. thirdh. based on the bml model. a main - road traffic flow model with two speeds on two dimensions is designed. this model simulate the traffic situation of one main road and several branches in the cit traffic lights placed on the crossing. vehicles breaking ~ vhile running and turning to other direction while jamming. we investigate the ~ ' e1ocitv and flo ~ ~ of the model when the initial densitvthe brake and turning probabilities. the green to signal rati3. thc number of the branches and the period of the signal are changed. then the reasons causing all the kinds of phenomena are analvzed. finallv. we simulate the bml model using the method of lattice boltzmann which ~ vas brought out by liu mu - renand obtain the velocity - density graph similar to the previous result. the upper critical densiw above which there are oniv jamming configurations. and the lo ~ ver critical density below which there are only moving configurations are the same as before. the boltzmann function which is on the lattices shows the moving and jaxmning transition obviouslv. thus it proves the possibilit of this method on the traffic research
接著,建立了和研究了二維二速的主幹道模型,該模型模擬了城市交通中一條主幹道,多條支道的交通情況,在幹道與支道的交叉路口設置紅綠燈,車輛在運行中可以有對突發事件發生反應的剎車,在發生堵塞時,路口的車輛可考慮通過轉向來緩解交通等各種實際情況的發生,給出了車輛演化的演化方程,並通過計算機模擬,研究模型在改變車輛的初始密度、剎車概率、轉向概率、支道數、紅綠燈信號的綠信比、紅綠燈信號周期等各種情況下支、主幹道車輛的速度、流量的變化,並分析在各種情況下交通狀況的成因,提出改善交通的有效措施。最後,在劉慕仁提出的用格子boltzmann方法研究一維決定論交通流的思路下,將此法推廣到對二維bml模型的模擬上,得到了與用以往方法的研究結果相類似的速度-密度圖線,且車輛從運動相到堵塞相轉變的上下臨界密度是一致的,同時分別給出車輛在處于暢通相和堵塞相時, boltzmann函數在格子上的分佈情況,進一步驗證了此法的可行性。Considering the fuzziness of some boundary conditions enviroment media, and especially some loads in the engineering structure analysis, we go further into the computation based on the dynamic problem of fuzzy finite element ( ffe ), study further and systematically the analysis and solution. the principle of fuzzy minimum potential energy is established, and the balance equation of fuzzy finite element is reasoned by making fuzzy variation. at the same time, the dynamic balance equation of stochastic by making stochastic variation , also the fuzzy stochastic dynamic balance equation is deduced. based the theory that the degree of the fuzziness and probability can be measured, in the other word, by using the concept of fuzzy entropy and entropy, pure fuzzy dynamic structure is given through transforming the probability to fuzziness. for the fuzzy parameter can be regarded as a fuzzy vector with dimensions, the structure ' s eigenvalue, by the theory of small parameter
建立了模糊瞬時最小勢能原理,運用模糊變分原理導出了模糊有限元動力平衡方程;同時,利用隨機變分原理導出了動力問題的隨機有限元方程,同時得到了模糊隨機動力問題的有限元平衡方程。根據模糊度和概率度可以度量的原理,即利用模糊熵和概率熵的概念,把結構的隨機性等效地轉化為結構的模糊性,得到純粹模糊性的動力結構。把結構所具有的模糊參數看作一個維的模糊向量,利用小參數攝動原理,把結構的特徵值,特徵向量和位移都在模糊向量的均值處進行泰勒展開,得到一組遞歸方程,即可以求得結構的模糊特徵值,特徵向量和模糊位移。The summery and review of exiting exchange rate regime choice theory literature are done in second chapter. among other things, the fixed and floating exchange rate dispute, optimum currency area, open economy macroeconomic model, design of intermediate exchange rate regime, currency crisis model and corner solution, exchange rate regime choice in developing countries and the positive study on exchange rate regime are discussed intensively. one finding is that the mainstream exchange rate regime literatures are always critical to the exiting prevailing exchange rate regime and resort to ever proved unsuccessful regimes to cure the problem in sight
第三章轉向對中國當前匯率制度的分析,在簡略概述其發展演化過程后,對當前我國匯率制度安排的成敗得失進行了評價,指出其基本適應了中國改革開放的需要,在中國避免東亞金融危機中發揮了重要作用,但現存匯率制度在效率、運行成本、對貨幣政策自主性的影響以及風險累積上仍存在著缺陷,這些缺陷在經濟進一步開放條件下有可能成為新的不穩定性因素。分享友人
