该实验从诸多气体状态变化中选取了3个关键的状态,实验设计巧妙,整个实验中涉及的理论分析过程复杂,实验操作有很多不可控因素,因此如何在实验教学中把握实验的设计思想,找到测量的关键点显得尤为重要。本文旨在分析实验过程的基础上,利用力学中“回复力”的概念,使学生快速掌握实验过程的变化规律,并以“压强”为控制因素,进行数据记录,从而使学生把握了实验测量的关键点,提高了实验的教学效率。
The experiment selected three key states from many gas state changes, the experimental design was ingenious, the theoretical analysis process involved in the whole experiment was complicated, and there were many uncontrollable factors in experimental operation. Therefore, how to grasp the experimental design idea in experimental teaching, It is particularly important to find the key points of the measurement. The purpose of this paper is to analyze the experimental process based on the use of mechanics “resilience ” concept, to enable students to quickly grasp the changing rules of the experimental process, and “pressure ” as the controlling factor for data recording, so that students Grasp the key points of experimental measurement, improve the teaching efficiency of the experiment.
