许多书籍对木炭在氧气中燃烧的实验有这样一段叙述：做木炭在氧气中燃烧的实验时，应将燃烧着的木炭慢慢伸向盛有氧气的集气瓶底部，否则，木炭燃烧生成的二氧化碳会聚集在集气瓶下方，将氧气排出，使木炭与氧气隔绝，燃烧很快停止。对此，笔者提出异议，试与同仁共同商榷。关 Many books describe the experiment of burning charcoal in oxygen: when the experiment of burning charcoal in oxygen, the burning charcoal should be slowly extended to the bottom of the gas cylinder with oxygen.
