【摘要】 本文介绍海洋环境要素的声光集成测量原理和测量方法。文中以作者主持的海洋 863项目“声光悬浮沙粒径谱测量仪”为例 ,列举了声速、声衰减、悬浮泥沙粒径谱的测量结果。海洋声速、声衰减、温度、盐度、悬浮物等都是海水的重要参数。这些参数的测量 ,对海洋开发、海洋环保、海洋军事有重要的意义。更多还原

【Abstract】 In this paper, Ultrasonic optic integration measurement principle and method about ocean environment elements are introduced. Taking 863 818 project, "Acoustics optic Suspended Sand Size Measurement System", as an example, the measurement results about speed, attenuation, suspended sand size distribution are listed. Ocean sound speed, attenuation, suspended sand size and so on are all important ocean parameters. Measurements of these parameters are important for ocean development, ocean environmental protection, and ocean military affairs.更多还原
