“如图1,在一条张紧的绳子上挂几个摆,其中 A、B 的摆长相等.当 A 摆(下文称母摆)沿垂直于纸面方向振动的时候,通过张紧的绳子给其它各摆(下文称子摆)施加驱动力,使其余各摆做受迫振动.…”.这是人教版高中物理教材中介绍的共振摆实验,该实验在人教版教材中长期保留并沿用至今.可是教师们在使用 “As shown in Fig. 1, several pendulums are hung on a tight rope, where the swing lengths of A and B are equal. When the A pendulum (hereinafter referred to as the pendulum) vibrates perpendicular to the paper surface, it passes through the tension. The rope applies the driving force to the other pendulums (hereinafter referred to as the pendulum) so that the rest of the pendulums are forced to vibrate....”. This is the resonance pendulum experiment introduced in the PEP physics textbook for senior high school students. In the mid- to long-term retention and use so far, but teachers are using
