This paper proposes the theorem of moment about mass acceleration of the particle and the system of particles (absolute motion and relative motion).

本文提出质点和质点系(绝对运动和相对运动)质量加速度矩定理。

The mathematical method is used to prove composition theorem of acceleration of a particle when the carrier motion is rotation.

用数学方法证明牵连运动为转动时点的加速度合成定理。

So what I'm saying here is we are specializing to a limited class of motion where the particle has a definite acceleration, a.

我在这里想说的是,我们正在专门讨论一类问题,这些问题中,质点都有一个确定的加速度a
