消不定因素法在质点群抛射运动中的应用

APPLICATION OF DELETING UNCERTAIN ACTORS TO PROJECTILE MOTION OF PARTICLE SYSTEM

本文研究重力场内质点群的抛射运动的轨迹,采用了消去质点的方向角的方法,从而一次性地确定了质点群抛射轨迹对应的特殊点位置,比常规方法鲜明简捷。

The trajectory of the projectile motion of the particle system in the gravitational field is researched. The deleting direction angle method is used. The positions of specific points corresponded with projectile trajectory may be determined at a time. The advantages of this method are cleares and simples.
