【摘要】 以1987年调查资料为基础总结了该湾海水和底质沉积物中锌的集散规律,并以一个代表性的水平剖面和两个垂直剖面分析了锌的变化动态.通过回归计算得出锌在水平距离上的变化方程.最后得出大连湾锌的变化动态趋势和底质、海水锌污染程度三点结论.更多还原

【Abstract】 The variation in zinc contents of sea water and sediments along two vertical profiles and a horizontal profile across Dalian Bay were investigated. The horizontal variation of zinc content with distance (L) for water may be described as:and for sediment:The following equation presents the relationship of zinc contents between water and sediments:更多还原
