中文摘要:
      本文介绍了声强测量技术在水下结构辐射噪声近场测量中的实际测量系统,特别是水下声系统的扫描平面的实现方法及定位误差控制方法最后讨论和分析了实际测量结果,从而说明该系统用水下声强测量是可行的
英文摘要:
      in this paper, a practical sound intensity measurement system used for measuring the radiation noise in the near field of an under water structure is presented, in particular the arrangement for realizing plane scanning of the under water sound receiveing system, and the method of position error cofltrol. The measured results are analyzed and discussed. The results show that it is feasible to apply the system to the measurment of sound intensity from under water structures.
