中文摘要：采用"风筝悬挂湿烛"大气Cl-沉降速率样品收集方法,利用离子色谱法分析样品溶液Cl-的浓度,获得了夏季不同月份、不同垂直高度近海大气中Cl-沉降速率,利用Pearson相关系数法分析了环境因素对Cl-沉降速率的影响。结果表明:南海岛屿夏季三个月大气Cl-沉降速率在10~100 m范围内的垂向分布呈反"S"分布;南海岛屿夏季高空大气Cl-沉降速率从6月到8月逐渐降低。

外文摘要：The deposition rate of Cl-is the important influence factor for the corrosion of high-altitude marine engineering equipment in marine atmosphere.For sampling the Cl-deposition rate at different heights,a so called"kite hanging wet-candles"method was invented,while the Cl-concentrations of the collected samples were analyzed by ion chromatography.The effect of environmental factors on the Cldeposition rate was analyzed by the Pearson correlation coefficient method.At the Hainan island of the South China Sea,the distribution of the Cl-deposition rates exhibits a reverse"S"-shape in the range of10 m to 100 m vertical scope in the summer time,however,the Cl-deposition rates were gradually reduced in the period from June to August.
