| Abstract: | In this paper,according to the theory of P=P1 P2......,Steam distillation can be changed into steam refluence by improving the experimental instruments The result is that the experiment phenomenon is more obvious,and that it can be used in the teaching of quantity relation and proved the relationship between theory and practical problem,which makes better effect on teaching |
