    By analysing stereo-structures of the reaction products in several types of reactions,such as addition reation of alkene,β-elimination reaction of alcohol and the halohydrocabon,pericyclic reaction,we summarized the relationship between reactant structures and reaction mechanisms. Based on the summarization,we concluded a convenient algebraic method which can be used to predict the product stereo-structures in these reactions.
