运用贮气瓶贮存气体,在课堂中可进行边讲边实验,我们在甲烷、乙烯、乙炔的性质教学中,取得了较好的效果。现介绍一种简易的贮气瓶的组装和使用方法。用广口瓶、分液漏斗、三孔橡胶塞、橡胶管、弹簧夹等常用器材,就可组装成如图1所示的简易贮气瓶。图1　简易贮气瓶　　　图2　代 Using gas storage bottles to store gas, we can conduct side-to-side experiments in the classroom. We have achieved good results in teaching the nature of methane, ethylene, and acetylene. A simple method of assembling and using a gas cylinder is introduced. With a wide mouth bottle, a separatory funnel, a three-hole rubber stopper, a rubber tube, a spring clip, and other common equipment, a simple gas cylinder as shown in FIG. 1 can be assembled.
