背景技术Background technique
物理学是研究物质运动最一般规律和物质基本结构的学科。作为自然科学的带头学科，物理学研究大至宇宙，小至基本粒子等一切物质最基本的运动形式和规律，因此成为其他各自然科学学科的研究基础。物理教材中的许多概念、规律都是通过实验引出并进行验证，但受限于硬件建设的不足，多数中学的物理实验并不全在实验室进行，而是由物理教师在教室内通过教具进行展示。目前，物理教学中所使用的展示架结构简单，功能单一，使得很多学生理解起来很困难，导致教课效果不佳。Physics is a subject that studies the most general laws of motion of matter and the basic structure of matter. As the leading discipline of natural science, physics studies the most basic forms and laws of motion of all matter, ranging from the universe to elementary particles, and thus becomes the research basis of other natural science disciplines. Many concepts and laws in physics textbooks are derived and verified through experiments, but due to the lack of hardware construction, most middle school physics experiments are not all carried out in the laboratory, but are displayed by physics teachers in the classroom through teaching aids . At present, the display racks used in physics teaching have a simple structure and a single function, which makes it difficult for many students to understand, resulting in poor teaching effects.
