    在此基礎上，通過結合壁面漫反射模型下分子反射速度的抽樣方法，發展了一種從邊界熱流求得與壁面碰撞分子的平均反射特徵溫度的逆溫度抽樣演算法。
  2. In this paper, some characteristics of flow movement and sediment transport are analyzed by using the flume experiment data. the cross section of compound channel can be divided into four regions : the undisturbed region in main channel, the interactive region between channel and plain, the undisturbed region in flood plain and the boundary region. in the undisturbed regions, the distribution of longitudinal velocity along the depth has the feature of lograithmic. whereas, in the interactive region, the longitudinal velocity does not obey the logarithmic distribution law, but it can expressed as a revised logarithmic function by using a wake function. on the basis of the kinematic equation the velocity distribution of transverse velocity is obtained. in the boundary region, the longitudinal velocity obeys the law of parabolic distribution. furthermore, according to the simplified diffusion equation, the transverse distribution of sediment concentration in the interactive region is deduced. the analysis is in good agreement with the measured data

    本文根據漫灘水流的運動特點，將漫灘水流的復式斷面分為主槽平衡區、灘槽交互區、灘地平衡區及邊壁區等4個區，並給出了各區寬度的經驗公式.根據灘槽交互區垂線流速分佈的變化特點，提出了附加尾流函數的對數流速分佈公式.在簡化水流運動方程和泥沙擴散方程的基礎上，對灘槽交互區內垂線平均流速及含沙量沿橫向分佈進行了理論分析，提出了反映灘槽水流動量交換強度的橫向渦量粘性系數及橫向擴散系數的表達式，得到了漫灘水流垂線平均流速及含沙量沿橫向分佈的解析解，並與實測資料吻合較好
  3. The comparison of the component particles of baijiaziu profile and mafangtan profile with that of modern flood plain substance of weihe river indicates that the river impetus of weihe river has gradually been getting weaker, which reveals that it has gradually been getting dryer since the last 1300 years

    西安高陵白家嘴河流沉積物粒度隨深度的變化及其與渭河現代河漫灘沉積物粒度特徵的對比表明，渭河近1 3ha來有流量減少，流速減慢，水深變淺的發展趨勢。
  4. A new method is presented. the travel time, including the time delays associated with overland folw pathways, is obtained. it is expected that the hillslope velocity and the stream velocity are different, and different equation is used. in the method, the fact that velocity increases going downstream in river systems is taken into account. after the travel time of each cell being calculated, the frequency distribution of the times of arrival of individual water droplets at the catchment outlet - giuh, is obtained

    提出了一種匯流時間計算方法，匯流時間中包括坡地漫流時間和河道匯流時間。方法中坡地單元的匯流速度與河道單元的匯流速度採用不同的計算公式，同時考慮流速沿河道向下游的變化。流域中每一個網格單元的匯流時間得到后，將其看作隨機變量，進行統計分析后，得到匯流時間的頻率分佈? giuh 。
  5. In boundary treatment, the model turns into generally adds coarseness boundary made of specially complex many coarseness body in the physical model experiment as the coarseness body highly and discharges the density to add the coarseness spot as the main characteristic whole, both to avoid the location within the body of this complex mathematical simulation problems, and could realize this model after to simulate the apron that adds the coarseness namely adds the coarseness section downriver speed of flow to the downriver current of water base speed of flow influence in to hang upward

    該模型在邊界處理時，將物理模型試驗中由特別復雜的多個加糙體組成的加糙邊界概化成以糙體高度為主要特徵的整個加糙部位，既避開了對加糙體內部進行極其復雜數學模擬的這一難題，又能實現模擬海漫加糙段下游水流流速在垂向上的分佈變化這一主要目的。在獲得基本的入流流速分佈、初始水位及加糙體的絕對高度和加糙段長度的情況下，能迅速模擬出加糙段下游各個斷面在垂向上的流速分佈情況。
