| 摘 要： | 利用易得用品对氧气的实验室制取装置进行微型化改进，若选用NnO2和H2O2作反应物，一组实验药品的耗资仅是常规实验的20％~50％，且实验效果好，根据实际对比教学分析，改进后的实验不但节省实验经费，而且能较好地完成实验教学任务，有利于大面积培养学生的实验技能，在贫困地区的中学有一定的推广价值．

| Abstract: | It's quite economical to use cheap implements to improve the apparatus in producing oxygen in lab to micromitniturization. For instance, we use MnO2 and H2O2 as reaction materials, the cost of such experiment is just 20~25 penent of a conventional experiment and the result is even better. With the comparative analysis of the two different ways of experiments, we find that it's not only economical but also saving-time.Besides it's helpful for the students to improve their ability and skills and for the teachers to accomplish their teaching plan. We think it's very valuable to be popularized in the undeveloped areas. |
