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。

一个巨大的钟摆隶属于一个小小的钟。
Modeling an inverted pendulum. Generally the inverted pendulum system is modeled as a linear system, and hence the modeling is valid only for small oscillations of the pendulum.
为倒立摆建模。通常倒立摆系统建模成一个线形系统，因此模型只对小幅度摆动的摆才有效。
The structure principle of three line pendulum can be used to measure the moment of inertia of small missiles, submunition, aeroplane model and other structural members.
利用三线摆的结构原理可以测量小型弹箭、子弹头、飞机模型及其他构件的惯性矩。
The structure principle of three line pendulum is outlined, and the calculation methods of its shimmy period in small and large Angle are presented.
