中文摘要：

我们在 2004 年 11 月在华南海(SCS ) 执行了一个长期的声学的繁殖实验。在水卷变化的影响是小的的地方，实验的环境与等温的健全速度侧面，意味着底部参数能很好从声学的信号被估计。我们转换了由使用联合与哈密尔顿沉积处理倒置的匹配的地的一个混合倒置计划的沉积的声学的参数实验关系和传播损失数据。数字结果与实验数据显示出优秀同意，显示转换参数的有效性。关键词 geoacoustic 倒置 - 匹配的地处理 - 传播损失由中国科学院的知识革新节目支持了(没有。KZCX1-YW-12-02 ) 并且中国的国家自然科学基础(Nos. 10974218 并且 10734100 )

英文摘要：

We performed a long range acoustic propagation experiment in the South China Sea （SCS） in November 2004. The environment of the experiment was with an isothermal sound speed profile, where influence of water volume fluctuation was small, meaning that bottom parameters can be well estimated from acoustic signals. We inverted the acoustic parameters of sediment by using a hybrid inversion scheme that combines the matched field processing inversion with Hamilton sediment empirical relationship and transmission loss data. The numerical results show excellent agreement with the experiment data, indicating validity of the inverted parameters.
