在准备实验的过程中,体会到本实验的目的在于引导学生通过观察以掌握甲烷及乙烯的性质。同时再做进一步的比较,找出甲烷与乙烯在性质上的异同,但如果分别先后做甲烷、乙烯的燃烧,甲烷、乙烯对溴的作用,甲烷、乙烯对氧化剂的作用,这不仅花费时问,影响进度,而更主要的是不能直接比较。于是我就采取了如下的装置及操作方法。

In preparing the experiment, I realized that the purpose of this experiment is to guide students to observe the nature of methane and ethylene through observation. At the same time, further comparison is made to find out the similarities and differences between methane and ethylene. However, if methane and ethylene are burned separately, methane and ethylene to bromine and methane and ethylene to oxidant are not only time-consuming , Affect the progress, but more importantly, can not be directly compared. So I took the following devices and methods of operation.
