Application of BP Artificial Neural Network in Quantitative Structure-Retention Relationship Analysis of Chlorinated Hydroxybenazldehydes

In this paper,the relationship between quantitative structure and gas chromatographic retention value of chlorinated hydroxybenzaldehydes were discussed by using BP artificial neural network.And then the parallel research using Multi -Factor regression was done to it.In the end,the diagram of oblique factor score value abtained from factor analysis with quantitative structure and gas chromatographic retention value showed the differentiae between the two methods discussed above.
