摘　　要：自持式剖面浮标在水中自由沉浮,具有隐秘性好、易投弃、体积小、重量轻、移动速度慢和制造成本低的特点,可用于长期、连续海洋观测及水下安全监视。文中介绍了全球Argo海洋观测网,综述了自持式剖面浮标发展历程及国内外研究现状。针对国产自持式剖面浮标不能满足现代海洋观测的需求,设计了2000 m以下水深工作的“浮星”自持式剖面浮标,填补了国内空白。“浮星”采用可变体积式浮力调节装置、硼硅玻璃球体作为耐压壳体,可搭载CTD、溶解氧等多种传感器,具有定深悬停、卫星定位和双向通讯等功能。目前,工程样机顺利通过实验室测试、南海海试、西太平洋可靠性测试,实现了4000 m水深下潜,验证了承压密封、浮力调节、通信控制等多项功能指标及整体可靠性、稳定性,为逐步实现全水深工作奠定基础。The autonomous profiling float can freely descend and ascend in the water.Because of its features of secrecy,easy to deployment,small volume,light weight,slow moving and low manufacturing cost,it can be used for long-term and continuous ocean observations and underwater safety monitoring.This paper introduces ocean observations with the global Argo array,and summa-rizes the development history of autonomous profiling floats andthe present research status at home and abroad.According to the fact thatthe domestic autonomous profiling floats cannot meet the needs of modern ocean observations,the"FUXING"autonomous profiling floats with working depths beyond 2000 m are designed to fill the technological gap.The variable buoyancy engine adjusts buoyancy by changing itself volume.The spherical glass made of borosilicate is used as a pressure housing.It has sufficient capacity to load CTD,dissolved oxygen sensor and other devices.The floats can hover at a setting depth.Satellites determine its position at the sea surface,and the floats transmit their data and receive control command via the satellites.At present,the engineering prototype has successfully passed some tests in the laboratory,the South China Sea,and the Western Pacific,verifying a number of functional indicators such as pressure housing seal,buoyancy regulation,communication control,and overall reliability and stability.It has also successfully descended to 4000 m laying foundation for the gradual realization of full-depth work.
