摘要
本文系统讨论了工程材料对可持续发展社会的影响和作用。归纳和提出了材料三角形，即材料的功能性、环境性和经济性的相互关系。以可持续发展思想为核心，阐述了环境材料与教育的关系。另一方面，明确定义了等效环境指数（Ｉｉ）、环境因子（ＥＦｋ）、环境负荷（ＥＬＶ）三个术语，从而给出具体材料的环境影响定量评价值。最后计算了某些工程材料的环境负荷值。
Effect of engineering materials on sustainable development society is systematically studied, in the paper. A material triangle, including an interactive relationship among function, environment, and economics, is presented. On the ground of sustainable development, many relations, such as ecomaterials and education, are discussed. On the other hand, equivalent environment index (Ii), environmental factor(EFk), and environmental loadings (ELV) are clearly defined. Finally, the environmental loadings of some engineering materials are given out.
