摘　　要：本文论述了作者研制成功的拖曳荧光计系统。该系统的荧光传感器采用了光源调制和信号同步解调技术，同时在受光器上采用了专用遮光导水暗盒及弯曲导水管，确保荧光传感器在探测体积内水体及时交换，并能有效地消除海中太阳光的影响。系统能在任一日光强度下从海表层至８０ｍ水深任一深度，走航拖曳速度在２～１０ｋｎ内平稳地水平工作。该拖曳体内安装有荧光传感器、温度传感器、深度传感器和多路传输电子线路装置。通过一根直径为１４ｍｍ的电源／信号传输七蕊铠装电缆将拖曳体与手摇绞车及船上控制器、数据采集、记录显示器连接在一起，可以同时测量光学和水文参数，这些数据为０～５Ｖ模拟电压量输出。该系统进行了多次水池和海上现场实验及应用，达到了预期设计目标。并且借助于荧光示踪染料完成了多处海区的水体混合扩散测量实验任务，建立了实验观测方法。本文还介绍了该系统的构造。A towed fluorometer system was develped successfuly by authors Because the sencer of flurometer adopt light source modulated、signal synchronous and the specific lightproof cover,interferomitric signal from daylight are removed The system can work excellent from surface to 80 meters under water,it’s towspeed is 2～10knots The towed body contains the fluorescence,temperature and depth sencers and elechomre equipment It is connected to the deck control and display uits through a cable with 7 cores、14mm in diameter Optics and hydrograph data measured are 0～5V analogons signal Water mixing diffusion experiment were carried out using fluorescence trancers in several marine regions Experiment methed is suted up In this paper,it also introduces the system construction,in site measmement data and application
