简谐振动是机械振动中最简单最基本的一种运动形式.根据中学物理教学大纲的要求,现行高中物理课本中主要分析了简单的弹簧振子和单摆的基本的运动规律.为了开发学生思维,扩大视野,笔者在教学过程中对简谐振动的判断和计算周期的方法通过典型举例进行了扩展,促进了这部分内容的教学效果.
Harmonic vibration is the simplest and most basic form of motion in mechanical vibration.According to the requirements of high school physics syllabus, the basic laws of movement of simple spring oscillator and pendulum are mainly analyzed in current high school physics textbook.In order to develop students’ thinking , Broaden their horizons, the author in the teaching process of Jane harmonic vibration judgment and calculation cycle of the method by a typical example has been extended to promote the teaching content of this part.
