【摘要】 提出一种有色金属材料LCA定量评价方法———综合比例系数法 .根据金属元素的环境特征、实际提取冶金过程和生物效应等要素 ,确立了纯金属的环境负荷定量计算原则并求出其相对环境负荷 ,然后由此计算金属材料的环境负荷比例系数 ;再根据推导出的模型计算出金属材料的环境负荷定量值 .并对ZL110和ZA8两种材料进行LCA实例定量评价更多还原

【Abstract】 A method of quantitative assessment using of comprehensive percentage coefficient for non ferrous metals is presented. On the basis of the relational factors, which organically synthesize the environmental feathers, processes of metallurgy and biological effects, the relative environmental load values of pure metals are calculated. Then according to the new model presented for non ferrous metals, ELV values of materials are quantitatively given, such as ZL110 alloy and ZA8 alloy.更多还原
