aquifer parameter 解釋
含水層參數
  • aquifer : n. (其含水量足可成為泉或井的)蓄水層。
  • parameter : n. 1. 【數學】參數,變數;參詞;參項。2. 【物理學】參量;(結晶體的)標軸。3. 〈廢語〉【天文學】通徑。vt. -ize 使參數化。
  1. Application of the algorithm for different observed head data sets indicate that the model can be successfully applied for aquifer systems where data available may be sparse and with errors. calculated groundwater heads by identification results in fourteen parameter areas are fit for observed heads in field, and flowing filed is similar. the study demonstrates the effectiveness of the ga global optimization model for parameter identification, which is an important step towards real system simulation and effective planning and management of groundwater resources

    通過算例研究,表明上述演算法可行,且rbf神經網路方法和退火遺傳演算法對地下水系統參數的識別效果都較好,而退火遺傳演算法較之標準的遺傳演算法具有更好的收斂性將演算法應用到北京市密懷順地區,在收集、分析研究區資料基礎上,建立了北京市密懷順平原區地下水模擬模型,並用遺傳演算法進行了地下水系統參數識別,在十四個分區情況下,計算水位與實際水位擬合的較好,各應力期末的計算與實測等水位線基本一致,表明該識別值較為合理。
  2. The calculation result effectively indicate the change rule with the time and space of water table of the aquifer, soft dank aquifer, parameter in process of wells work in the pit

    計算成果較好地刻畫了基坑井群的實施過程中含水層、弱透水層水頭、參數的時空變化規律。
  3. Let h be the deviation of the true shape of the free surface from the shape it would hold if the water were distributed in a steady state, then 1 sine. snnaxnnnshxthxthxttfsxkbs using darcy s law and ssqnl, the discharge from the aquifer is given by 0001. xssxsxnnnnsnhqsntfkuhxhhfkuhhxhqfkuhxfsslfkttsk it is easy to get the mean subsurface runoff of this grid bqt. bqtql 626 science in china : series d earth sciences for the aquifer, the continuity equation holds. dsntlqsntdt new subsurface runoff parameterization, a synthetical recharge series is applied to some aquifers with dif - ferent parameters. firstly, the parameter is tested : three aquifers with the same following parameters are used : d 1. 5 m, k 0. 0008 m s, l 100 m, f 0. 34, p 0. 5, three different slopes are considered : 0. 002, 0. 02, 0. 05. fig

    在該模型中有三個重要的模型參數的:整個潛水面平均厚度的線性化參數d ,整個潛水面的平均坡度,以及飽和和水力傳導度k .首先考察一下該模型對于坡度的敏感性:取d 1 . 5 m , k 0 . 0008 m s , l 100 m , f 0 . 34 , p 0 . 5 .取下面三個不同的坡度0 . 002 , 0 . 02 , 0 . 05 .圖2 a給出是實驗給定的入滲強度的時間序列,圖2 b給出的是分別選取這三個坡度時該地下徑流機制所產生的不同的地下徑流的情況
  4. By the method used in 13, 32, one can estimate the mean depth d and the effective length l in each grid. the slope of the aquifer can also be calculated through an analysis of the digital elevation model. the two parameters a and b in the quasi - steady subsurface model can be calculated by the following method : the nonlinearity parameter b is taken to be 2. 0, the parameter a can be calculated by plotting the values for dq dt versus q in a log - log graph 13
