下面在线为同学们整理了雅思阅读辅导:锚式擒纵机构的优势,供各位考生参考。
阅读段落
To address this, a variation on the original escapement was invented in 1670, in England. It was called the anchor escapement, which was a lever-based device shaped like a ships anchor. The motion of a pendulum rocks this device so that it catches and then releases each tooth of the escape wheel, in turn allowing it to turn a precise amount. Unlike the original form used in early pendulum clocks, the anchor escapement permitted the pendulum to travel in a very small arc. Moreover, this invention allowed the use of a long pendulum which could beat a second and thus led to the development of a new floor-standing case design, which became known as the grandfather clock.
