相对中误差

结合黄河下游现行测量条件，指出：①河道输沙量测验的相对中误差为1.7%~2.5%，能满足了解河道输沙情况的要求；

Considering the existing observation condition of the lower Yellow River , it points out that ( I ) the relative measuring error of channel sediment discharge is 1.7 % ~ 2.5 % , which can meet the requirements of channel sediment discharge ;
