It is found that the carbonization velocitycoefficient will not be constant but increased with the elevation of CO2 concentrations resulted from the air pollution.
According to data analysis of actual measure, this paper obtains perpendicular line current velocitycoefficient of measuring section and measuring discharge coefficient on the bridge.
经过实测资料的分析，得出了呼玛桥水文站桥测断面的垂线流速系数以及桥测流量系数。

The experiment shows that by changing the velocitycoefficient , the separation of boundary layer on pump vane can be controlled, and the performance of pump is improved and its hydraulic efficiency.
