本文论述了使用作者于1988年研制成功的国内第一台拖曳荧光计系统，通过改换荧光测量滤光片为中性游光片。于1988年至1989年首次在国内东、黄海倾废区分别进行了较大规模的海洋倾倒悬浮污染物质（粉煤灰和碱渣）的海洋深层追踪观场实时测量实验。由于该系统采用了短光程、正交测量的光学后向散射法，使得对悬浮颗粒物质具有3个数量级的测量范围（2～2000mg／l）、良好的线性关系和极高的精确度。工作深度从海表层到50m水深，走航拖曳速度为0～8kn。在测量实验中，该系统能在预定深度走航平稳地快速、连续测量人工投放在实验海区的悬浮颗粒物质浓度的时间、空间分布，取得了令人满意的结果。此方法测量悬浮颗粒物质的原理及其在测量性能方面优于光学前向散射法和衰减法。
This article discusses the use of the first tow fluorometer system successfully developed by the author in 1988, by changing the fluorescence measurement filter to neutral. For the first time in 1988 to 1989 in the domestic east and the Yellow Sea dumping areas, real-time measurements of ocean deep tracing observation of large-scale ocean dumping pollutants (fly ash and caustic sludge) were carried out respectively. Due to its short optical path and orthogonal backscattering method, the system has 3 orders of magnitude of measurement range (2 ~ 2000mg / l) for suspended particulate matter, good linearity and high accuracy. Depth of work from the sea surface to 50m depth, go towing speed of 0 ~ 8kn. In the measurement experiment, the system can go smoothly and rapidly at a predetermined depth and continuously measure the time and space distribution of the suspended particulate matter concentration in the experimental sea area and achieve satisfactory results. The principle of this method for measuring suspended particulate matter and its superior performance in measurement of optical forward scatter and decay methods.
