本文将稳健偏最小二乘法用于贵金属元素锇、钌的光度法同时测定．较好地解决了实际核准模型由于实验误差偏离正态分布使计算结果的精度遭到破坏的问题；对化学量测中引入的异常点有较强的校正功能，Ⅲ从而确保了分析结果的准确性。方法的相对标准偏差Os为3．3％，Ru为2．1％。
In this paper, the robust partial least squares method is applied to the simultaneous determination of osmium and ruthenium in noble metals. Which solves the problem that the accuracy of the calculation result is destroyed due to the deviations of the experimental error from the normal distribution in the actual approved model. It also has a strong correction function for the abnormal points introduced in the chemical measurement and thus ensures the accurate analysis result Sex. The relative standard deviation of the method was 3.3% for Os and 2.1% for Ru.
