【摘要】 磺胺甲噁唑和甲氧苄啶的紫外光谱严重重叠，本文构造和使用两个M估计的新的目标函数导函数(x)函数，并由此建立两个新稳健回归方法，以此解析重叠的吸收光谱，不经分离紫外分光光度法同时测定磺胺甲噁唑和甲氧苄啶，结果满意。为多组分同时测定提供了两个新稳健回归方法。更多还原

【Abstract】 Ultraviolet spectra of sulfamethoxazole and trimethoprim overlap seriously. Two derivative functions of target function of M e stimation have been constructed to resolve the overlapped spectra, and a robust regression method for the simultaneous spectrophotometric determination of sulfa methoxazole and trimethoprim was developed.\=更多还原
