摘　　要：针对氢气和氧气的爆鸣实验进行改进与探索 .为了使氢气和氧气爆鸣效果最佳 ,并符合教学要求 .这里采用了简单的自制反应装置来完成此实验的 .实验结果表明 ,取 10ml的盐酸 (分析纯与水的体积比为 1∶1) ,与 10g锌粒反应 ,在 8至 10s内点燃时 ,爆鸣效果最好 ,成功率达百分之百 ,安全 ,无危险 .This paper explores the demonstrating experiment on hydrogen and oxygen's burst. To obtain good effect and fit the request of teaching,a simple device made by ourselves was used to finish the experiment. The result of the experiment shows:10ml hydrogen pentachloride(the ratio of zedox and water is one to one),10g zinc,lighting between 8s to 10s the best bursting result comes out. The success rate is 100 percent,and this operation is safe.
