摘　　要：偏最小二乘法用于紫外可见光度分析测定多组分间相互作用较显著的铽、钍、铒稀土体系得到较好的结果.考查了波长和间隔选取对计算精度的影响,与卡尔曼滤波法对比,证明了本法的优越性和广泛适用性.Partial least-squares method is applied in quantitative determination of multi-component mixture of rare earth by UV spectrophotometry. The accuracy of calculation is studied by changing the ranges and intervals of wavelength. The results show its superiority to other numerical methods.
