海底中的声速对于水下声场计算、海底工程设计、沉积物的遥测分类以及其他许多实用问题都有密切的关系。然而由于海底中声速常随地区变化和它在测量上的不便,所以至今对它还了解得不够充分。近年来,随着水声学和海洋开发的进展,有关的科技人员为取得对海底声速的更多了解进行了许多努力。在浅海中,沉积物中的声速变化一般发生在海底表面下数米和数十米的深度内。  相似文献   

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
