这里所说的μc和σc,是指海洋声速场主要统计参数——声速的数学期望值和标准偏差而言的。 目前,在海洋考察中,除用声速仪直接获得声速参数外,更多地获取声速参数的方法,乃是通过温盐观测值来换算成声速的,特别是对历史资料的整理尤其如此。这就必然使得μc和σc的统计计算,显得相当繁琐。本文试图通过温盐的主要统计参量——温盐的数学期
As used herein, μc and σc refer to the mathematical expectation and standard deviation of the main statistical parameter of the sound velocity field of the ocean, the sound velocity. At present, in the course of ocean exploration, in addition to directly obtaining the sound velocity parameters by using the sound velocity meter, the method of acquiring more sound velocity parameters is converted into the sound velocity by observing the temperature and salinity values, especially the sorting of historical data. This inevitably makes the statistical calculation of μc and σc, it is quite complicated. This article attempts to pass the main statistical parameter of the temperature salt - the temperature period of the salt
