摘　　要：本研究基于对全国电脑消费者的调研,采用Logistic模型对我国电脑的销售量和平均保有量进行了预测,采用群体平衡模型估算了我国废旧电脑的产生量,采用质量守恒原理对废旧电脑中赋存的有价金属的量做了预测分析.结果表明,到2030年,我国废旧电脑的产生量约为368百万台,其中金的存量约为157.74t、银的存量约为478.12t、钯的存量约为46.72t,铜的存量约为10.91万t.Study on the generation amount and the metal stock of obsolete computers is important for building areasonable recycling system of waste.In this study,the average possession and sales of computers,the generation amountand the deposit of valuable metals in obsolete computers were predicted using logistic model,population balance modeland material balance principle,respectively.The results indicated that the generation amount of obsolete computers inChina was about368million units in2030.The stock quantities of gold,silver and palladium contained in obsoletecomputers would reach157.74,478.12and46.72tons,respectively.And the stock quantity of copper would reach109.1thousand tons.
