摘要: 本文研究在混合物中只有一部分组份为已知物,而同时又含有未知化合物,如草药等其它天然物质的紫外-红外光谱的计算机定量分析方法。该方法可不经化学分离,仅由实际绘制的光谱图,根据线性规划法计算机求解来定量已知成份。同时又可由计算机直接得到未知成份的差谱,为未知成份的定性提供依据。

Abstract: For mixtures containing a unknown component, computer quantitative analysis has been investigated. It can be applied to herbal drugs, synthetic material,environmental monitor and biochemical samples etc.This method is based on UVor IRspectra of mixtures. Firstly, the quantities- of known components are calculated by linear-programming method, then the subtrac-tive spectrum of a unknown component is solved on computer.
