| 摘 要： | 对南沙海区部分站位微表层和次表层的ｐＨ、碱度、密度和表面张力进行了测定。结果表明：微表层的表面张力低于次表层的表面张力，并且表面张力与溶解有机碳（ＤＯＣ）相关；微表层的ｐＨ低于次表层的ｐＨ，并探讨了其原因；微表层的碱度和密度一般高于次表层，同时对其原因进行了探讨。

| Abstract: | The pH, alkality, density and surface tension at some sampling stations of the surface microlayer and subsurface water in the Nansha region were determined. The results show that the surface tension in the surface microlayer is lower than that of the subsurface water and the surface tension is associated with the DOC. The pH value in the surface microlayer is lower than that of the subsurface water, and the reason for this is discussed. The alkality and density in the surface microlayer are usually greater than those of the subsurface water and the main reason is also discussed. |
