为使中学物理实验达到预期效果,确保实验者在实验过程中免受意外伤害,保护仪器设备及周围环境,实验教师必须采取必要的预防措施。下面,笔者围绕中学物理实验仪器保存、实验装置、实验过程三个环节中的预防措施谈谈自己的认识。一、仪器保存的预防措施1.防形变。在长时间存放后,许多仪器受重力作用影响而致其整体或部件产生形变,进而影响到实验结果。这就要求针对不同特征的仪器采取相应的放
In order to achieve the expected results of high school physics experiments to ensure that experimenters in the experiment from accidental injury, protection of equipment and the surrounding environment, the experimental teachers must take the necessary precautions. Next, I talk about my understanding of preventive measures in the three aspects of the preservation of high school physics experiment equipment, experimental devices, the experimental process. First, the instrument preservation precautions 1. Prevent deformation. After being stored for a long period of time, many instruments are deformed by the effect of gravity and cause deformation of the whole or the part, thereby affecting the experimental results. This requires that different characteristics of the instrument to take the appropriate release
