　　摘 要：ADCP目前已在我國水利行業廣泛使用，但儀器的檢測校準一直沒能實現，主要原因是靜水槽的水體長期靜置，水體中的懸浮顆粒很少，使得ADCP在水槽環境中缺乏有效的水中反射物，造成對儀器測速性能的檢測難以實現。從分析ADCP工作原理和功能模塊入手，研究如何解決在靜水槽環境下實現ADCP檢測的難點，提出通過在水槽水體中增加納米氣泡從而提高對儀器超聲波信號的反射能力這一關鍵技術，以東部某水槽為例，提出納米氣泡發生系統的具體布設方法，并進行實測驗證。通過實際測試驗證和對測試結果數據的分析，證明此方法可以實現ADCP的靜水槽檢測，也為我國大量ADCP的可靠使用和數據的合理性合法性檢驗提供路徑。

　　Abstract: ADCP has been widely used in water conservancy industry in China, but the inspection and calibration of the instrument has not been realized. The main reason is that water body in the still water tank is static for a long time and there are few suspended particles in the water body, which makes ADCP lack of effective water reflectors in the water tank, resulting in the difficulty of detecting the speed measurement performance of the instrument. From analyzing working principle and functional modules of ADCP, this paper studies how to solve the difficulty of ADCP inspection in the still water tank and puts forward the key technology of increasing the reflection ability of the instrument ultrasonic signal by adding nano bubbles in the water tank. Taking a water tank in the east as an example, this paper puts forward the specific layout method of nano bubble generation system and verify it by actual measurement. After the actual test verification and the analysis of test result data, it is proved that this method realize the static water tank inspection of ADCP and provide a path for the reliable use of large numbers of ADCP, the rationality and legitimacy inspection of data in China.
