摘要
在P总 =PA+PB+…原理的基础上通过实验仪器的改进 ,把水蒸汽蒸馏变成水蒸汽回流 .让实验现象更明显 ,并可进行定量关系的教学 ,进一步证明理论知识与解决实际问题的关系 ,使教学效果更好 .
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
