为了帮助广大中学物理教师教好和学生学好物理课,陕西师范大学物理系贺瑞灵老师设计制造了一套“初中物理综合演示实验仪器”。这套仪器分两部分,第一部分包括力学和热学,共有元件72种170件,能够装配演示129个物理实验,基本上满足初中物理教学的要求。它的特点是:(1)一物多用,安装方便,结构简单,便于教师讲解仪器的性能和原理;(2)造价便宜,估计力、热部分只需200元左右,不需要建筑专门的保管室和购置
In order to help the majority of middle school physics teachers teach well and students learn physics lessons, the teacher of the Department of Physics at Shaanxi Normal University, He Ruiling, designed and manufactured a set of “junior middle school physics comprehensive demonstration experimental apparatus.” This set of equipment consists of two parts. The first part includes mechanics and thermal sciences. There are 72 types of components and 170 items. It can assemble and demonstrate 129 physics experiments, which basically meet the requirements of junior high school physics teaching. Its characteristics are: (1) multiple uses, easy installation, simple structure, easy for teachers to explain the performance and principles of the instrument; (2) cheap, estimated strength, hot part only about 200 yuan, does not require special construction custody Room and purchase
