本文对海水温度探测器进行研究，研制了一种新型的海水温度测量传感器链，用以测量浅海中水层薄、温度变化剧烈的不同深度处温度动态变化。能实时显承现场温度、声速剖面，为海洋环境数值预报和灾害性海况遥测提供监视技术。水温环境数据也能用于声呐作用距离预报、拖曳线列阵布放深度选择、潜艇航行安全保障。 In this paper, the seawater temperature probe is studied, and a new type of seawater temperature measurement sensor chain is developed to measure the dynamic change of temperature at different depths where water layer is thin and the temperature changes drastically in the shallow sea. It can display real-time temperature and sound velocity profiles in real time to provide monitoring technology for numerical forecasting of the marine environment and telemetry of disastrous sea conditions. Water temperature environment data can also be used for distance prediction of sonar, deployment depth array towed array, submarine navigation security.
