海洋研究和海洋开发是新技术革命的重要内容.海洋开发迫切,需要了解海底底质和地层的情况,海底勘探过去主要靠钻探和取样.但在海洋条件下,钻探和取样非常费时和费力,代价很大.因此,使用声学方法,快速地了解海底底质及矿藏的情况,就成为非常必要. Marine research and development of the oceans are an important part of the new technological revolution. The development of the oceans is urgent and requires understanding of the sea floor sediments and stratigraphy. In the past, seabed exploration was mainly based on drilling and sampling. However, drilling and sampling were very time-consuming and labor-intensive under ocean conditions, So it is very expensive.Therefore, the use of acoustic methods to quickly understand the situation of the sea floor sediments and minerals, it becomes very necessary.
