摘要
本文将环境意识引入金属材料学科。在考察金属元素分布的环境特征和生物效应的基础上，定义了环境影响因子ＥＡＦ，并引出了强度环境负荷比（σｂ／ρ）／ＥＡＦ等参数。
Environmental consciousness is penetrated into meteallic matrials science,in this paper. On the basis of viewing the feature of environmental distribution and the bioloical effects of metallic elements, environmentally affected factor(EAF) is defined, meanwhile parameters such as ratio of strength to environmental loading are presented,According to these parameters,the relationships of performance with environmental loading for various metals are assessed comprehensively.
