The nacre of molluscan shell, which is composed of inorganic aragonite tablets and a few percent of organic polymers filling between the tablets, is a wonderful natural composite material.

软体动物的贝壳珍珠质是由文石板片(CaCO_3晶体)以及少量填充在板片之间的有机质组成的一种天然的复合材料，具有复杂的形貌以及良好的力学性能、光学性能，其文石板片与有机基质交替叠层排列的微结构以及文石晶体的结晶学取向是珍珠层具有优异的力学性能的重要原因之一。

The nacre of molluscan shell, which is composed of inorganic aragonite tablets and a few percent of organic polymers filling between the tablets, is a wonderful natural composite material. It shows complex forms, and fascinating mechanical and optical properties.

软体动物的贝壳珍珠质是由文石板片(CaCO_3晶体)以及少量填充在板片之间的有机质组成的一种天然的复合材料，具有复杂的形貌以及良好的力学性能、光学性能，其文石板片与有机基质交替叠层排列的微结构以及文石晶体的结晶学取向是珍珠层具有优异的力学性能的重要原因之一。

Island in a group of people on the island apart from a few samples do not yield anything other than the production of the necessities of life can not be the island's residents in a shell called the RMB, as the money to spend, that is, a 3 coconut shells, fresh water a drum shells, etc.

在一个岛上有一群人，岛上除了几样产量不大的生活必需品以外什么也生产不了，岛上的居民用一种叫RMB的贝壳，作为钱来花，就是椰子一个3贝壳，淡水一桶5贝壳等等。

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。
