摘　　要：针对聚氨酯泡塑吸附-原子吸收光谱法测定金矿石中金的分析测定过程和数学模型,找出了影响测量不确定度的主要来源,对各不确定度分量进行了评定,并计算得到了合成标准不确定度和扩展不确定度,给出了相应的测定结果表示法。The analyzing process and mathematics model of gold determination process in gold ores by FAAS with the polyurethane foam adsorption are established. The main sources of determination uncertainty are found out. The component of caused uncertainty is made quantum chemistry calculation. The standard uncertainty and spread uncertainty are gained. The standard representation of determination results in proposed.
