  1. Following this algorithm, the base flow can be calcu - lated from the observed discharge as follows : 1, 22bbqiqiqi where i is the time step in the discharge records, qb is the base flow, q is the total runoff, and is the re - cession constant during periods with no surface runoff. the parameter can be determined through a dis - charge recession analysis

    地下徑流的推算公式如下1 1 . 22bbqiqiqi ? ? ? ? 26其中i表示推算的時間步數， qb是地下徑流， q是總的徑流.表示沒有降水時候流量消退系數，可以通過沒有降水時候的流量消退資料推算出出來
  2. Abstract : based on the principle of balance of surface irrigation water volume, a method for determination of field average infiltration parameter according to the irrigation data is introduced

    文摘:本文根據水量平衡原理，提出了利用大田畦灌灌水資料推求土壤入滲參數的方法，在此基礎上，又提出了利用波涌灌水流推進和消退資料確定間歇入滲減滲率系數的方法。
  3. Through examination of the recession limbs of the observed hydrographs, during periods with no rain and thus no surface runoff, one can determine the value of. for this catchment, a value of 0. 8 is obtained. the simulated subsurface runoff at each grid is routed to the outlets through a unit - hydrograph method for overland flow and the linear saint - venant equation for channel flow to get the discharge at xixian station

    對所研究的流域而言，經過估算消退系數為0 . 8 .耦合著這兩種不同地下徑流機制的clm模型都可以計算出每個網格的地表地下徑流深，採用dag lohman 34 ， 35發展的匯流模型進行匯流由於是研究地下徑流，所以取每個網格的地表徑流為0 ，該模型採用單位線計算坡面匯流線性聖維南saint - venant equation進行河道匯流
  4. Moreover, experimental results have proved that the method is robust enough to some image degradation process such as cropping, jpeg compression and sharpening etc. embedded zerotree wavelet coding ( ezw ) algorithm, it is found that this algorithm does not make full use of the properties of human visual system ( hvs ) to eliminate visual redundancy

    實驗證明，該方法對剪裁、 jpeg壓縮和銳化等圖象退化處理均具有一定的抵抗力，是一種行之有效的水印嵌入方法。本文在對零樹編碼方法研究的基礎上，針對零樹編碼方法沒有充分利用hvs特性來有效消除視覺冗餘的缺點，提出了一種基於小波系數的零樹編碼方案。
