The phylogeny and applied prospect of MES are summarized in the paper. The principle of this system is analyzed from the point of view of acoustics. The surveying and filtering technology of auxiliary parameters, sounding data and the theory of image form, backscatter strength data processing, are researched deeply in the paper. The optimal model of velocity of sound is given. For sound ray tracing, some methods of correction of sound ray curve are developed. At the same time, an ideal model of sound ray tracing is proved and given. The GPS technology is applied for the determination of tide, attitude of vessel. Moreover, some methods are given. As an important topic, the systematic error is discussed in the paper. Some filtering methods are researched in this paper. Based on the current methods of image processing, the procedure and methods are tested and given that adapt to sonar image processing.

本文研究的工作是在总结多波束声纳测深系统的发展历史、应用前景的基础上，从声学角度分析了多波束系统的工作原理；对多波束辅助参数的测定和滤波方法、测深数据的滤波方法、多波束声纳图像的形成机理、图像处理以及最终应用等作了比较深入的研究；得出了适合于多波束精密深度计算的最优声速模型和声线改正模型；提出了 GPS 载波相位定位技术用于多波束辅助参数测量的思想、算法，改善了多波束系统的作业模式；系统地分析了深度数据的误差来源和类型，首次将系统误差作为影响测深精度的主要因素给以研究，并给出了削弱系统误差的方法，提高了深度数据的质量；对多波束声纳图像的形成、处理方法进行了细致的研究，给出了适合多波束图像处理的算法和流程，并从理论和实践上对声纳图像的应用进行了比较全面的研究。

3The results of disambiguity experiments show that:①If speakers are given appreciatecontext,he/she will provide disambiguation information by prosody;②Listeners have ability tomake full use of this prosody to help comprehension to ambiguous sentences;③Thedisambiguation effects of prosody are different in different kinds of ambiguous sentences;④Thevariations of breaks in front of ambiguous syllable and behind it are the main methods in structuralambiguous sentences;⑤Disambiguating demonstrative ambiguous sentences the importantmeans is setting up accent on the corresponding noun,the fundamental acoustic correlate isduration lengthening of corresponding noun.

歧义实验结果表明，如果提供合适的语境，在发音过程中，人能够运用韵律手段提供解歧信息；而听者在理解话语时也能够有效利用这一信息，达到对歧义句语义解歧的目的。在对歧义句进行适当归类的基础上，发现韵律对不同类型歧义句解歧效果不一。对层次切分歧义句和指代歧义句的深入研究表明，歧义音节前后停顿时长的变化是消解层次切分歧义的最主要的手段；发音人消解指代歧义的基本手段是在所指名词上设置相应的重音，其最主要的声学相关物是所指名词时长的延长。

His current project,Knossos,is a unusual blend of middle-eastern instrumentation with dense percussive layers of organic sounds and textured beats.Truly electro-acoustic in nature,the premise of the Knossos sound centers on the manipulation of eastern acoustic instruments with signal processing and ambient distress.Dann lives in the LA area and has worked with Solace, Shaman's Dream,Azam Ali from Vas,and a variety of other diverse musicians in the studio,and in improvised performance.

他现在是一个项目，克的中东和不寻常的敲击的层致密的有机的声音和纹理跳动真正的电声性质，为前提的声音在操作中心岛东声学设备和信号处理和周围的痛苦然后住在洛杉矶地区和曾经与安慰，萨满的梦想，Azam阿里从管，以及其他各种多样的音乐家在工作室，在即兴表演。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
