摘　　要：湍流在海洋能量和水体的交换演化中起着非常重要的作用。海洋湍流研究的发展和海洋湍流观测仪器的研发密切相关。世界上湍流观测仪器的研发起步于20世纪50年代,但是我国在湍流观测设备方面到目前为止仅仅处于起步和引进国外设备阶段。针对我国的情况,利用DSP技术设计电路,并通过电路对剪切湍流数据进行处理。用ALEC公司生产的湍流剖面仪测量的数据分别通过其公司自带软件和电路处理的结果进行对比,结果吻合较好。文中提供的方法解决了湍流数据量较大不利于远程数据传输的问题,为大面积长期的湍流观测提供了可能。Turbulence plays a significant role in ocean energy and mass exchange.The research of ocean turbulence is closely related to the development of ocean turbulence observation devices.Early in 1950＇s,foreign scientists began making and testing such devices.While,in China,we could almost do nothing but import such equipment to meet the demand in ocean turbulence research.DSP technology is applied in designing circuit,which is used to process data of turbulence shear.The data measured by TuboMap of ALEC Co.is compared with the results processed by circuits.The results show a good coordination.The solution provided has solved the problem of remote data transmission caused by large amount of turbulence data,which offer the possibility for long-term and large-scale turbulence observations.
