摘　　要："二重源解析"模型计算结果的误差是采样误差、样品处理误差、化学组分分析误差、数据处理误差以及数学模型误差等所有误差的积累。提出了"二重源解析"解析结果的相对误差和标准偏差表达式,并用之计算了某市利用"二重源解析"模型计算的源贡献值的相对误差和标准偏差,还针对从源排放出来的初始态颗粒物在传输过程中发生的扬尘态变化提出了扬尘转化率的概念和计算方法。The origin of error with 'double source apportion'of Atmospheric Particulate Matter was analyzed in the paper.It was put forward that the error with 'double source apportion' was accumulated from sample collecting,sample handling,chemical component analyzing,data processing,mathematical model and so on.The relative error and standard deviation of 'double source apportion' was expounded as expressions in the thesis.These formulas were used for calculating relative error and standard deviation of contribution...
