众所周知,前年化学高考试题难度较大,主要是实验题目“咬人”。但益阳市三中的考生却失分不多。家长自然感谢老师,而老师们则说:首先要给仪器管理员王曼夫记一功。王曼夫保管着近五千件教学仪器,分类严格,保管精细,做到了实物、卡片和帐目三相符。对其中任何一件仪器,他都能随时讲出名称、性能、存放位置。他爱护仪器,就象爱护自己的眼睛一样。二十多个春秋过去了,仪器的完好率和利用率一直在90%以上。使用了二十多年的显微镜,至今观察效果仍很清晰。三百多种试剂,很少变质失效。一九五五年配的无水硫酸钠,去年使用时,效果依然很好。 As we all know, the previous year’s chemistry exam questions were more difficult, mainly the experimental topic “biting people.” However, candidates in the middle school in Yiyang City did not score much. Parents naturally thank the teacher, and the teachers said: First of all, to instrument manager Wang Manfu remember one. Wang Manfu maintains nearly 5,000 teaching instruments, which are classified strictly and carefully preserved to achieve three-dimensional characters of physical objects, cards, and accounts. For any one of the instruments, he can always tell the name, performance, storage location. He loves the instrument, just like his own eyes. More than two decades have passed, and the availability and utilization of the instruments have been above 90%. The microscope has been used for more than 20 years and the observation effect so far is still very clear. More than 300 kinds of reagents, rarely metamorphosed into failure. The anhydrous sodium sulfate used in 1955 was still effective when it was used last year.
