推算公式 meaning in English

prediction equation

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
地下径流的推算公式如下1 1 . 22bbqiqiqi ? ? ? ? 26其中i表示推算的时间步数, qb是地下径流, q是总的径流.表示没有降水时候流量消退系数,可以通过没有降水时候的流量消退资料推算出出来
