| 摘 要： | 分析了我国1990至2004年锌制品的消费结构.给出了锌制品平均使用寿命的计算方法.在此基础上研究了我国1990至2004年间锌制品的平均使用寿命,结果表明我国锌制品的平均使用寿命逐年增加,分析原因是由于我国近年来镀锌制品及铜材产量大幅增加.计算了我国锌制品的折旧回收年限约为20年,为锌的循环分析及预测锌制品的消费发展趋势提供了数据基础.

| Abstract: | The consumption structure of zinc products from 1990 to 2004 in China is analyzed, for which the weighted averaging method is given to calculate the average service life of zine products. The result indicates that the average service life of the zinc products in China increased year by year in recent years on the whole because of the greatly increasing output of galvanized products and copper products. The calculation reveals that the depreciation/recovery period of the zinc products in China is 20 years. Thus, a data foundation is offered to calculate the cyclic consumption of zinc and predict the developmental trend of zinc products. |
