中文摘要:
      声速经验公式是海水中温度、盐度和静压力的函数,通过对直接测量声速和间接测量声速的分析,并应用近年来收集的南海声速剖面仪SVP和CTD数据,对九种声速经验公式计算的声速与直接测量声速的差异进行了分析,得出了声速经验公式的计算差异范围,结果表明各个声速经验公式各有优势,不同的公式适用的范围也不一样,并给出了在不同的范围内应用何种声速经验公式能获得较高精度的结论.
英文摘要:
      Empirical equation for sound velocity is the function of temperature, salinity and static pressure in sea water. After analyzing the sound velocity by direct measurement and indirect measurement, and utilizing the data collected by profiler SVP and CTD in South China Sea in recent years, the differences between the sound velocities calculated by nine kinds of empirical equations and the one with direct measurement are studied. The different scopes calculated by empirical equations for sound velocity are obtained. The result shows every empirical equation of sound velocity has its own advantage and their applicable scopes also differ. The conclusion is provided for using an appropriate empirical equation for sound velocity in actual situation to get higher accuracy.
