摘　　要：温盐深是反应海洋物理学特性的重要参数,是海洋水文观测的基本要素。CTD剖面仪(Conductivity-Temperature-Depth profiler)是进行海水温盐剖面观测的主要仪器,利用CTD剖面仪可精确测得水下不同深度上海水的温度和电导率参数,进而能够推算出海水盐度、密度、声速等相关信息,对于海洋经济开发、海上国防建设、海洋环境保护等都具有非常重要的意义。本文介绍了温盐深剖面测量技术的基本原理与发展现状,对几种典型的温盐深测量设备及各种海洋观测平台中搭载的CTD传感器进行了介绍,论述了CTD传感器的标定和测试技术,并对其发展趋势进行了分析。Temperature, salinity and depth are important parameters of the ocean physical properties as well as the basic elements of the ocean hydrological observation. Conductivity-temperature-depth（CTD） profiler is the main instrument for the observation of temperature and salinity profile which can measure the conductivity, temperature and depth parameters accurately, and calculate the other parameters of sea water, such as salinity, density and acoustic velocity. These data are crucial for the development of marine economy, marine national defense construction and the protection of the marine environment. The basic principle and development status of CTD measurement technology were reviewed in this paper. The typical CTD measuring instruments and CTD sensors installed on the ocean observation platforms were introduced. The calibration and testing technology of CTD sensors were discussed. Furthermore, the development trend were summarized.
