由于工作台摆动角度受机床结构的限制,小摆角五坐标数控机床不能直接进行离心叶轮的连续加工。
Unlike the original form used in early pendulum clocks, the anchor escapement permitted the pendulum to travel in a very small arc.
与在早期摆钟中使用的原始形式不同,锚擒纵装置允许钟摆沿非常小的弧线运动。
Of course this force was exceedingly small, compared with that of the earth; and for that reason the vibrations of this pendulum were by far slower than those of a common one.
当然,跟地球的引力比较,大球的引力极其微小;所以,小球的摆动比通常所见的摆动要缓慢得多。
But you never had to make any small-angle approximation with the spring as we had to do with the pendulum.
但是你不用用弹簧,做小角近似值,就像我们用摆做的一样。
