贵刊1995年第2期发表了陈老师《实验室用温度计示数模型制作》的文章,其经验介绍,无疑会给教学工作带来有益的帮助.日前,笔者拜读了该篇文章,结合我校制作的同类示教模型,提出一点改进建议,望广大同仁给予指正. In your issue of the second issue of 1995, the magazine issued an article by Professor Chen on “Modeling Thermometers for Laboratory Thermometers”. The experience of the presentation will undoubtedly bring useful help to the teaching work. Recently, the author read the article and combined it with me. The same model of teaching produced by the school, put forward some suggestions for improvement, hope the majority of my colleagues give corrections.
