摘　　要：中高水测验中水面流速系数对测流精度影响较大,基于卡拉苏(四)水文站断面和测验设施情况,采用比值法和相关分析法对该站的测流系数进行探讨,得出卡拉苏(四)水文站水面流速系数、半深流速系数为0.84、0.93;对水位流量关系曲线三种检验进行校核;可为提高测验精度,积累有关计算水面流速系数、半深系数率定工作提供借鉴。In the middle and high water test,the water surface velocity coefficient has a great influence on the flow measurement accuracy.Based on the cross-section and testing facilities of Karasu(IV)hydrological station,the ratio method and correlation analysis method are used to discuss the flow measurement coefficient of this station.The calculation results show that the water surface velocity coefficient and half-depth velocity coefficient of Karasu(IV)hydrological station are 0.84 and 0.93;Checking the three tests of the water level-discharge relationship curve can provide reference for improving the test accuracy and accumulating the calculation of the water surface velocity coefficient and the semi-depth coefficient calibration.
