摘要
简要分析了现行中学物理课本中关于受迫振动和共振的演示实验中存在的缺点,并针对其不足加以改进.改进后的实验装置演示效果更好,便于学生理解和掌握相应的物理规律.
Problems in the demonstrating experiment of forced vibration and resonance in current physics course are analyzed and effective amelioration methods are suggested. Using the new demonstrating experimental device, the teaching effect have been greatly improved, and it is more easy for the students to understand and master the physics law.
