【摘要】 本文讨论了北黄海１１个柱状岩芯样的颗粒物（＜０．０６３ｍｍ）中重金属的分布，采用统计学方法对Ｃｕ，Ｐｈ，Ｚｎ和Ｃｄ进行态性检验，用柱样稳定段（拐点以下）作为背景段，获得重金属环境背景值．更多还原

【Abstract】 This paper reported the distributions of the heary metals Cu,Pb,Zn,Cd in the finegrained sediments(<0. 063mm)of 11 cores from the North Huanghai Sea. The types of distrbution of the elements were tested by statistical analysis and the environment background values of them in the area were obtained by using the contents at the stable section(below the turning point)in the core as a background content.更多还原
