recession constant 中文意思是什麼
recession constant
解釋
後退常數-
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
