摘　　要：赵石窑水文站渠道位于横山区响水镇无定河左岸,常年平均流量六点多立方米每秒,下游一公里有发电站一座,水流流态常年受其影响,水位变幅较大。平常测验使用的是旋浆式流速仪进行测验,由于北方地区泥沙大,漂浮物多,旋浆式流速仪易被水草缠绕,对测验影响较大,且测验时间较长。而电波流速仪属非接触水面式的,测验时间短且安全。对赵石窑水文站渠道电波流速仪法和旋浆式流速仪法进行比测分析,率定电波流速仪的水面系数。The channel of Zhaoshiyao hydrological station is located on the left bank of Wuding River in Xiangshui Town,Hengshan District.The annual average flow rate is more than six cubic meters per second.There is a power station one kilometer downstream.The flow pattern is affected by it all the year round,and the water level varies greatly.The usual test uses a slurry flow meter for testing.Due to the large amount of sediment and floating matter in the northern region,the slurry flow meter is easy to be entangled by water grass,which has a great influence on the test and takes a long time.The wave current meter is a non-contact water surface type,and the test time is short and safe.The water surface coefficient of the electric wave current meter is calibrated by comparing and analyzing the channel electric wave current meter method and the rotary slurry current meter method of Zhaoshiyao hydrological station.
