摘　　要：盐度是研究海水物理、化学性质及其过程的一个重要参数,高质量盐度数据对海洋科学研究具有重要作用。实验室盐度计测量是获得高精度盐度数据的有效方法,盐度测量装置能否可靠运行,完善稳定的充排水取样系统必不可少。通过实验,提出了一种采用负压虹吸法充排水系统设计方案,详细介绍该方案中水路系统和电气控制部分的设计方案、设计原理。实验结果表明,该系统能够很好地完成样品的充水、排水、功能转换等相关操作,是一套稳定、可靠、操作方便的充排水取样装置。Salinity is an important parameter to research marine physical and chemical characteristics and their processes. The highly-accurate salinity data will make a great contribution to marine scientific research. The laboratory measurement of salinity is an effective way to obtain accurate salinity data. The reliability of salinity measuring device depends on a stable water filling-and- discharging system. Through the experiments, a design scheme for water filling-and-discharging system which adopts negative- pressure syphon method is proposed, following the design principle, scheme of water system and the electric control system. The result shows that this system can complete the water filling, discharging, the functional conversions, etc. which turns out that this system is a stable, liable, and easy-to-operate water filling-and-discharging sampling system.
