我系担负着很多教学实验课程,这些课程每年要消耗大量化学试剂、实验材料和玻璃仪器。前几年,我们对于我系一年究竟需要消耗多少各类物料,用得是否恰当,一直是不很清楚的。近年来,我们为了更好地保证教学需要,同时尽量防止积压浪费,进一步贯彻勤俭办学的方针,开始考虑采用定额 I am responsible for a large number of teaching experimental courses, these courses consume a large number of chemical reagents, laboratory materials and glass equipment. In the past few years, it has not always been clear to us whether the appropriate consumption of various types of materials is required for one year in my department. In recent years, in order to better ensure the teaching needs, we must try our best to prevent the backlog and waste and further implement the principle of running a school with diligence and frugality.
