摘　　要：本工作测定了西太平洋海域中海水、海水悬浮物和海面上雨水的元素组成和浓度。通过富集因子的计算,探讨海面上雨水中微量元素的富集程度及其来源,讨论了海面上气溶胶粒子大小与洗出因子的关系,结果表明不同质量粒径大小的微量元素在公海上具有相似的洗出因子。The elemental composition and concentrations of trace elements in seawater, suspended matters, and marine rain are presented for samples collected at the Western Pacific Regions. The cnri chment and sources for trace elements of marine rain are investigated through calculating enrichment factors. The relationship bet ween the particle size of marine aerosol and scavenging ratio are discussed. These results showed that trace elements with distinctly different mass particle size distribution exhibited similar scavenging ratio at the open ocean.
