笔者介绍一种装置简单,操作方便,绝对安全、效果明显的爆鸣气实验方法。一、实验装置如图1、单球干燥管;(可用眼药水瓶代替);2、直径约2毫米的铁丝电极(一般为镀锌铁丝,必须擦去镀层).极问距离要近;3、弓%氢氧化钠溶液;生、3一4.5V直流电源;5、导气管(可用塑料管代替)6、表面皿;7
The author introduces an experimental method of explosive gas that is simple, easy to operate, absolutely safe and effective. First, the experimental device Figure 1, a single ball drying tube; (available eye drops instead); 2, about 2 mm in diameter wire electrode (usually galvanized iron wire, must be removed by coating). Extremely close to ask the distance; 3, Bow% sodium hydroxide solution; raw, 3 - 4.5V DC power supply; 5, air pipe (replaceable with plastic pipe) 6, surface glass; 7
