VERTICAL DISTRIBUTIONS OF SOUND VELOCITY IN SEA FLOOR MEASURED IN SOUTH CHINA SEA AND HUANGHAI SEA 总被引:1,自引:0,他引:1
This paper presents the vertical distribution of sound velocity in the first few ten meters of the sea floor measured in the South China Sea (12 stations) and the Huanghai Sea (2 stations) by reflection and refraction methods.The apparent characters of the sediment samples and the velocities estimated from the sample porosities by Anderson's empirical equation basically coincide with the measured velocity structures.A new method called "total reflected ray method" has been used to interpret the reflection data. 相似文献

近年来,声学方法被愈来愈多地用于海底的探测。因此,如何从海底的回声波形中提取有关海底的信息是海洋声遥测中的一个重要问题。本文介绍我们近几年对手榴弹爆炸声海底反射波形分析的部分结果。由于某些浅地层剖面仪的声源波形已接近手榴弹的爆炸波形,因此,爆炸声的分析结果向实用的过渡是不困难的。 相似文献
