摘要
采用主成分回归紫外分光光度法分析白油中单环芳烃和多环芳烃的含量，运用计算机VB语言对实验数据进行回归分析。结果表明，主成分回归分光光度法对样品各组分的平均回收率在92．41％～99．28％，取得了满意的分析结果。
Principal component regression （PCR） method is used to analyse monocyclic and polycyclic aromatic hydrocarbons in white oil. The computer program of PCR is based on VB language. The experimental result shows that the average recovery of each component is all in the range from 92.41% to 99.28%. Each component obtains satisfactory result.
