Abstract: In the researches of the Quantitative Structure-Activity Relationship, one of the difficult problems is the representation and the extraction of molecule structural informations.In order to solve this problem generally, authors propose a numerical representation method of molecule structural factors——Structural Frame Model method(SFM).
First, a model for describing molecule structural factors is defined on a set of compounds being studied. In the set of compounds, there must be a common mole-cular backbone. From the model definitions, the factors reflecting the differences of molecular structures can be completely extracted.
Then the whole topological strcuture information can be transfered to a numerical matrix.

Key words: Stucture-Activity Relationship, Processing of structural information, Herbicides, Sulfonylurea
