摘要
利用纯氧、球形干燥管、细铁丝团等设计的一体化实验装置,解决了铁生锈实验时间长的问题,能让该实验在很短的时间内快速完成,从而提高了实验效率和课堂教学的有效性.
This paper designed integrated experiment device using pure oxygen, spherical drying tubes, and thin wire balls, solved the problem of long time for the iron corrosion experiment. The improved experiment could be completed in a very short time and thus improved the experiment efficiency and teaching effectiveness.
