摘　　要：详细分析了子弹射击木棒问题与子弹射击砂箱问题的区别,利用质心运动定理和角动量守恒定律说明了在什么情况下系统的动量才守恒。又引入打击中心的概念,指出了理论的实际应用。This paper detailed analysis the different to the problem of the bullet shoots the wooden staff with the problem of the bullet shoots the sand box. With the theorem of the motion of center of mass and the law of conservation of angular momentum explained the condition of momentum conservation of this system. And make use of the concept of attack center pointed out the actual application of this theories.

关 键 词：系统 动量 守恒条件
