The synchronization of two pendulum clocks hanging from a wall was first observed by Huygens during the XVII century. This type of synchronization is observed in other areas, and is fundamentally different from the problem of two clocks hanging from a moveable base. We present a model explaining the phase opposition synchronization of two pendulum clocks in those conditions. The predicted behaviour is observed experimentally, validating the model.
17世纪时,惠更斯首次观察到挂在墙上的两个摆钟的同步现象。这种同步类型在其他领域也有观察到,并且与挂在可移动基座上的两个时钟的问题有着根本的不同。我们提出了一个模型来解释在这些条件下两个摆钟的相位相反同步现象。通过实验观察到了预测的行为,从而验证了该模型。
