Further topics include kinematics, particle dynamics, motion relative to accelerated reference frames, work and energy, impulse and momentum, systems of particles and rigid body dynamics.

更进一步探讨运动学，质点动力学，于加速座标系上之运动行为，功，能量，冲量，动量和质点系统与刚体动力学。

So the research is important to the selection of the fire time and number of the impulse engine and serves as theory reference.

研究结果对脉冲发动机的点火起控点选择以及脉冲发动机的个数选择都有一定参考价值。
