本文针对现行基础化学教材中易燃、易爆、有毒、有害物质所采用的敞口式或半封闭式实验装置和实验方法进行了改革。在发表《全封闭隔离式毒气实验研究》一文之后,又以氢气为例,总结出一套“全封闭组合式实验装置和操作方法”。由于对有毒害物质采取有效的吸收和转化,确保了实验人员的健康和环境不被污染,从而有助于培养学生的环境意识和环境保护能力,同时也体现了化学实验课的内在规律性。
In this paper, based on the existing basic chemistry teaching materials, flammable, explosive, toxic and hazardous substances used in open or semi-closed experimental devices and experimental methods were reformed. In the publication of “fully isolated isolated gas experimental study,” a text, but also to hydrogen, for example, summed up a “fully enclosed combination of experimental devices and methods of operation.” Due to the effective absorption and transformation of poisonous substances, the health of the experimenter and the environment are not polluted, which helps to cultivate students’ environmental awareness and environmental protection ability, and also reflects the inherent regularity of the chemistry experiment class.
