本文为作者在1979年9月英国巴恩大学举行的“非线性声学在水声中的应用”讨论会上的一篇报告,介绍了当前最重要的几种应用以及在设备研制和海上实验方面取得的显著成就,现摘译如下: 1.高分辨率测深 海底及底层剖面测量是参量声源最成功的应用之一,它充分利用了参量声源在吸收较小的低频下工作,波束却狭窄而无旁瓣这一优点,应用场合包括深水作业中观测海底管道系统,探查海底底层剖面分布,寻找沉埋物等等。
This is a report by the author at the Symposium “The Application of Nonlinear Acoustic Acoustic Water Applications,” held at the University of Bath in September 1979, to present some of the most important applications at present as well as the applications in equipment development and offshore experiments Significant achievements made, are now extracted as follows: 1. High-resolution sounding seafloor and bottom profile measurement is one of the most successful application of parametric sound source, which takes full advantage of the parametric sound source in the absorption of low-frequency work under the beam But narrow and without side-lobe advantages, applications include deep-sea operations in the observation of the submarine pipeline system to explore the distribution of the bottom section of the seafloor, looking for buried and so on.
