| 摘要: |
| 近十年来，探测海底几十米至几百米松散沉积层分层结构的“海底浅地层剖面仪”已逐步发展定型，并广泛用于海底工程施工和海洋地质研究方面。这种浅地层剖面仪主要采用以下几种声源装置：电致伸缩器件、磁致伸缩器件、电磁脉冲声源、电火花放电器以及气枪。
浅层剖面仪实际上是一种以地层为探测目标的主动声纳，本文给出了有关的声纳方程式，它将有助于这类仪器的工程设计和性能预报。
从探层声纳方程式出发，采用电磁脉冲声源研制了浅层剖面仪，获得了穿透地层几十米的较高分辨率的记录。对此，本文也作了简单的介绍。 |

| Abstract: |
| The sonar equation for sub-bottom profiling measurement was introduced. Following this equation, some accoustic considerations about testing of profiling system were given. The system provides a sub-bottom profiling record with a higher resolution by using a “boomer” as source. It penetrates the un-consolidated sediment up to a depth of tens of meters. |
