将奇异值分解和主成分回归相结合，首次用于药物的含量测定，采用紫外分光光度法同时测定克感敏片中的非那西丁、氨基比林和咖啡因的含量．其结果明显优于最小二乘法．
The combination of singular value decomposition and principal component regression was used for the first time to determine the content of drugs. The contents of phenacetin, aminopyrine and caffeine were determined simultaneously by UV spectrophotometry. The result is significantly better than the least squares method.
