摘　　要：选取实验室中常用的9种基准物质作为实验对象,分别用微波照射法和电烘箱干燥法进行定时干燥.结果表明,利用微波照射法在中高火档或高火档干燥样品时,所需干燥时间由原来的13h缩短至810min,同时,可节约电能80%以上.Nine primary standard substances in lab were prepared, and they were dried by microwave and tradition separately,The results show that drying time changes into 8 - 10min from 1 - 3h by ＂MID - HIGH＂ or ＂HIGH＂of microwave,and 80% of electricity was saved.
