| 摘 要： | 将示波器显示波形的原理与单摆运动相类比,讨论了示波器中光电子运动的合成与单摆运动中沙漏与硬纸板运动的合成的相通之处,并通过对单摆产生不同波形情况的具体分析,利用简单易懂的知识对示波器的工作原理进行简化.这种类比简化的思维对物理教学的教改具有重要的意义.

| Abstract: | The working principle of oscillograph is too complex for the students to master.The movement of the photoelectron in oscillograph and the sandglass and chipboard in single pendulum is uniform.In order to simplify the complex principle,the movement of single pendulum is contrasted to the graph forming principle of oscillograph,and the formation of different graph in single pendulum is analyzed.The analogism method is significant to the innovation of physics teaching. |
