摘　　要：介绍了溶解氧的单位、过饱和状态、水中溶解氧测量的意义和三大类溶解氧分析方法。分析了不同方法之间的原理差异,并进行了实验比较。结果显示,在1013 hPa的不同温度(10℃、20℃和30℃)时上述方法的测量结果无显著性差异。与此同时,分析和比较YSI几款型号的溶解氧测定仪,给出了建议的应用场合和选择依据。The unit of dissolved oxygen,supersaturated state,significance of measuring dissolved oxygen in different water bodies and three kinds of analytical methods of dissolved oxygen are introduced.The experimental results show that there is no significant difference in the measurement results of the above methods at 1013 hPa at different temperatures(10℃,20℃and 30℃).At the same time,several models of YSI are analyzed and compared,and the application occasions and selection basis are suggested.
