为了使同学进一步钻研所学的科学知识,并培养他们的创造能力,本学期初我们组织了课外活动小组--电工组。由於学校的领导和支持,老师的辅导,同学们积极活动,到现在已经制成了六种电学仪器模型。其中我们以为感应起电机的制作是最有价值的。第一,起电机是一般小学和中等学校物理教学上不可缺少的一种仪器,第二,起电机是市价较贵,既难买到又不便於运输,第三,用容易找到的旧材料和简单的方法制作成本费不高,效果良好,
In order to make students further study the scientific knowledge and develop their creative ability, we organized an extracurricular activities group - the electrician group at the beginning of the semester. Due to the leadership and support of the school, the guidance of the teachers and the active activities of the students, up to now six kinds of electrical instrument models have been made. Which we think induction motor production is the most valuable. First, starting a motor is an indispensable instrument for physics teaching in general primary and secondary schools. Second, starting a motor is a more expensive market. It is difficult to buy and not easy to transport. Thirdly, using old materials that are easy to find and Simple method of production cost is not high, the effect is good,
