    本文首先用數值方法，計算了各種頻率的平面波通過以上幾種典型的一維準周期和非周期鏈的透射系數，並據此研究了這幾種一維準周期和非周期鏈的熱通量j與粒子數n之間的關系，得出j n ~ （ a - 1 ） ， 0 . 5 1 ，與系統中在位勢的大小有關，並與其他系統的結果作了比較。
  3. The premise to assure qos is to provide sufficient resource to meet demands. we come up with a method to partition the resources of web cluster for each class with its resource demand and priority requirement taken for granted, where system processing time or average access rates is summed up for each class periodically and resource demands is evaluated with stretch factor as performance metric. also the nodes marked in number will be orderly assigned to the classes ordered in priorities, which helps to maintain data locality and improves memory cache hits

    資源滿足需求是實現服務質量保證的前提，為滿足業務類動態的資源需求，我們提出一種支持業務類優先級和資源需求的資源劃分方法，通過按周期對業務類請求處理時間或平均訪問率進行統計，以響應擴展因子為質量指標對業務類預期的資源需求作出評估，採取按主機編號有序地分配給按優先級排序的業務類，減少業務類資源變動和提高主存cache命中率。

  6. 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。
