近年来我多次参加中、小学实验室检查评比的工作,每次总会看到有些教学仪器,因为实验员的维护保养措施没有及时到位,造成了一些不应有的损失。究其原因,或是实验员由任课教师兼任,因重教学轻仪器维护保养,实验后仪器不加保养即入橱;或是实验员新上任,不熟悉各种仪器的性能,缺少 In recent years, I have participated in the laboratory inspections and comparisons of primary and secondary schools several times. Each time, I always see some teaching equipment because the maintenance and repair measures of the laboratory technicians are not put in place in time, resulting in some undue losses. The reason is that the experimenter is served by the teacher, because of the heavy maintenance of the teaching equipment, the equipment is not added to the cabinet after the experiment, or the laboratory technician is newly appointed and is not familiar with the performance of various instruments.
