长江口水域声速测量时间间隔研究分析
Study on Time Interval of Acounstic Velocity Measuring at the Yangtze River Estuary
摘要
Abstract
s:In view of the time interval of acoustic velocity profile measuring at the Yangtze River estuary,by calculating the hourly change in the sound velocity at the testing points set in the south-north channel at the Yangtze River estuary,the mathematical statistic method was used to estimate the characteristic parameters for the change in the acoustic velocity profile in the above waters,and study the temporal and spatial characteristics of the change in the acoustic velocity profile in the south-north channel at the Yangtze River estuary.The research results showed the minimum time interval of acoustic velocity profile measuring that met the appropriate sounding precision in different waters.关键词
