摘　　要：本文较详细地讨论了海洋声学体散射理论和海水中悬浮物扩散理论。对比DFS－2100型声学测量系统和TCL－204型双频探鱼声纳的技术性能之后，对国产TKL－204声学系统作了重大改进，使其适于对海洋倾废物进行测量和跟踪。现场实验结果表明，经过改进后的系统是成功的，同时也证明了文中所用的扩散理论对分析海洋中悬浮物的扩散规律是有用的。The theory of acoustlc volume scattering from ocean and the diffusion theory of sus pended materlals in ocean are discussed detalledly. Baced on the comparison between model DFS- 2 100 system and model TCL - 204 two frequencies fishlng sonar, We did important improvement on modtl TCL-204 system made in China, and made it to measure and track ocean dumping materials. The results of experiment in situ have proved that the improved system is successful, and t11at the diffusion theory is useful for analyzlng the diffusiility of suspended materials in the ocean.
