摘　　要：溶解氧是地表水水质的一个重要指标,是鱼虾等水生生物的生长和存活的决定因素之一。文章简要介绍了溶解氧的概念、过饱和现象以及溶解氧的监测分析方法,并通过两种分析方法的比对实验验证了溶解氧过饱和现象的存在。最后就溶解氧过饱和现象的原因进行了探讨。Surface water dissolved oxygen is an important indicator of water quality, fish and other aquatic organisms is the growth and survival of one of the determinants. The paper briefly introduced the concept of dissolved oxygen, dissolved oxygen supersaturation and monitoring and analysis methods, and through two methods of experimental verification than the existence of the phenomenon of supersaturation of dissolved oxygen. Finally, the dissolved oxygen supersaturation of the reasons were discussed.
