| 中文摘要: |
| 声学多普勒流速剖面仪（ADCP）具有便捷高效、不扰动流场、测验历时短、测速范围大等特点，因而被广泛应用于水文行业流量测验.不同于流速仪法流量测验，目前国内还没有专门对走航式ADCP进行检定的专业机构.为全面了解宜春水文局各测报中心所用ADCP仪器性能，找出影响走航式ADCP测量成果的主要误差来源，本文采用不同方法对辖区内8台不同厂家、不同型号ADCP进行了比测分析.结果表明，8台ADCP目前性能良好，测验精度均能满足规范要求. |
| 英文摘要: |
| Acoustic Doppler Current Profilers（ADCP）is widely employed in flow measurement in hydrological industry because of its convenience and efficiency，high measure speed and extensive speed range.At present，there is no instrument calibrating institution of ADCP in our country，which is different from current-meter method.In order to understand the instrument capability of cruising ADCP used in different hydrometric stations of Yichun hydrological bureau and find out the main factors that influence the accuracy，8 ADCPs from different manufacturers were calibrated in this paper.The result showed that all of the 8 ADCPs had high performance，which could meet the requirements of specifications of surveys. |
