Contents of Zn, Cu, Cd and Pb in Shell of oyster and offshore water from Dalian gulf, Laohu beach, Fujia Zhuang beach, Lingshui bay, Lvshun and Jinzhou are studied by Anodic Stripping Voltammetry in order to establish a relationship between offshore seawater and heavy metal content in shells. Through monitoring the seawater and shells we researched whether the shells could replace the soft tissue of oyster shells as an indicator of marine environment changes in hope of finding a more convenient and accurate carrier for monitoring marine heavy metal.

本论文以大连湾、老虎滩、付家庄、凌水湾、旅顺及金州六个区域的近岸海水及牡蛎贝壳为研究对象，应用阳极溶出伏安法对其锌、镉、铅、铜的含量进行分析，旨在通过监测大连近海水域及贝壳重金属含量来研究二者的相关性，探索是否可以利用贝壳替代贝类软组织来指示海域环境的变化情况，从而找到一种更为简便、更为可靠的监测海洋重金属的载体。

结果表明，蛤仔对大多数元素的富集作用最强，是胶州湾典型的指示生物；双埠蛤仔体内的As和Cr的含量已超出食品卫生标准；团岛贻贝体内的Cd、Cu和Zn的含量已超出食品卫生标准和一般底栖生物的最高允许浓度，说明胶州湾不同区域已有了不同程度的重金属污染，且年际变化较为明显，重金属污染程度在不断加剧。

Based on the Miedema model and Tanaka equation, a new method for calculating the parameters in the molecular interaction volume model has been developed to predict the activity coefficient s of multicomponent liquid alloys, in which not experimental data but only some physical properties of elements are required.

基于Miedema模型和Tanaka关系，提出了计算分子相互作用体积模型参数的新方法。该方法仅需知道元素的某些物理性质而无须熔体的实验数据，简化了计算多元合金熔体活度系数的步骤。分别计算了Ti-6Al-4V和Ti-5Al-2.5Sn在不同温度下组元活度系数的变化，计算了多种铜基合金以及Zn-Sn-Pb-Cd-Bi合金的活度或活度系数与组元配比的关系；并与Wilson模型进行了比较，计算值与实验值较好吻合
