摘　　要：本文介绍用系数倍率法测定两组分体系的基本原理和实验方法,不经分离干扰组分而直接测定复方降压片中硫酸双肼酞嗪的含量,其操作简易、快速,工作量小,平均回收率98.9％,变异系数0.50％,结果满意。This paper introduces the basic principle and experimental tecrtnigue measarmg birary constituent system by means of K-ratio spectrophotometry. DHPS in hypotensive tablets is solved in O.1mol ?L-1 HC1 and Analyzed with 751-G spectrophoto meter at 302nm and 322nm. The results show that the average recovery is 98.9% and coeffcient of variation is 0.50%.
