Abstract This paper discussed the origin and development of phlogiston theory,hackled the historical process of oxidation theory.On the basis of these chemical histories,this paper made it clear that the historical value of the law of conservation of mass not only depended on paying attention to the total quality of the materials in the reaction,the differences of system and surrounding also had important significance.And then,this paper discussed the implications of the building process of the law of conservation of mass,and the value of the law of conservation of mass in the chemistry teaching of junior high school from the angle of the reaction system and surrounding.
