摘　　要：针对洪水涨落影响的水位流量关系,研究并指出以往研究中存在的瑕疵。重新推导了受洪水涨落影响的同水位稳定流流量与不稳定流流量之差和不稳定流流量之间的微分式,推导了受洪水涨落影响的同水位稳定流流量与不稳定流流量之间的关系式。从新的角度再次证明了同水位的不稳定流流量与稳定流流量之差和不稳定流流量之间具有函数关系,其对洪水涨落影响的水位流量关系资料整编具有一定意义。Aiming at stage and discharge relationship affected by the flood rise and fall,it studied and pointed out the defects existing in the previous researches.The differential equation was derived between the difference value of the steady discharge and unsteady discharge and be⁃tween the unsteady discharge affected by flood rise and fall.The relationship equation was derived between the steady discharge and unsteady discharge under the same stage affected by flood rise and fall.From a new point of view,the conclusion(the difference value between the steady discharge and unsteady discharge with the same discharge and between the unsteady discharge existed functional relation)was proved again.It was of certain significance to data processing in the stage discharge relationship affected by the flood rise and fall.
