As an analogy, before a law of gravitation could be formulated, it was necessary to have the concepts of 'acceleration' and 'weight,' and there had to be commonly accepted measures of these terms.

作为一个类比，就像在形成万有引力定律之前，必须有“加速度”和“重力”的概念，而且必须有对这些概念的广泛接受的度量方式。

With an example given, index error curve is obtained by applying acceleration law of deformed trapeze on a computer.

并结合实例，运用变形梯形加速度运动规律，通过微机计算，得出了该凸轮机构从动件的分度误差曲线。

Hence, new physics would take into consideration at least one of three possibilities: clock acceleration, a modification of the law of gravity, or modified inertia.

因此，新的物理原理可能至少是这三种可能性之一：时钟加速，修改引力定律或者修改惯性。
