摘　　要：2009年9月至2010年6月，利用B＆K8104和TC4033水听器作为比对校准用标准水听器，杭州应用声学研究所和俄罗斯国立物理技术与无线电工程测量研究院之间开展了250Hz～200kHz频段水声声压的比对校准。尽管中俄双方所使用的测量方法、校准技术和测量装置不同，但双方的校准结果非常一致，最大的偏差只有0．36dB。经中俄双方专家讨论和分析后一致认为，两个部门在该频段内校准水声声压所采用的测量方法和校准技术是正确的，测量装置给出的校准结果是精确、可靠的。Using B＆K 8104 and TC 4033 as standard hydrophones, an underwater acoustics sound pressure calibration comparison in the frequency range 250 Hz to 200 kHz was carried out between HAARI of China and VNIIFTRI of Russia from September, 2009 to June, 2010. Although the different measurement methods, calibration techniques and measurement facilities were used, the calibration results from both sides were very close, and the maximum deviation was only O. 36 dB. After the discussing and analyzing by the experts from China and Russia, the consensus conclusion was gotten that the measurement methods and calibration techniques using in the comparison calibration are correct, and the results from measurement facilities are accurate and reliable.
