1引言不同版本的物理教材中对“共振”下的定义差异很大.高中物理旧教材[1]是这样下的定义:“当驱动力的频率跟物体的固有频率相等的时候,受迫振动的振幅最大,这种现象叫共振”.而新教材[2]则定义为:“驱动力的频率接近物体的固有频率时,受迫振动的振幅增大,这种现象叫共振”. 1 Introduction The definition of “resonance” varies greatly among different versions of physics textbooks. The old textbook of high school physics [1] was defined as follows: “When the frequency of the driving force is equal to the natural frequency of the object, forced vibration The amplitude is the largest, this phenomenon is called resonance.” The new textbook [2] is defined as: “When the frequency of the driving force is close to the natural frequency of the object, the amplitude of the forced vibration increases, this phenomenon is called resonance.”
