利用碰撞定律求解斜碰问题

指出斜碰情况下在垂直于相互作用冲量方向，动量守恒定律表现为两球保持各自速度不变，只是沿着相互作用冲量方向，两球才交换动量，并且在这个方向仍然有分离速度与接近速度成正比．同时运用这种分解方法求解了平面斜碰问题和三维空间斜碰问题，讨论了不同情况下解的个数及物理意义。

Solution Finding or Problem of Slanting Collision with the Law of Collision

The solution of slanting collision with the law of collsion is discussed.It ispointed out that,under condition of slanting collision, component velocity of both balls inthe direction perpendicular to the impulse vector of interaction keep unchanged as the conse-quence of the law of conservation of momentum. Exehange of the momentum between twoballs takes place only in the direction of impulse of interaction and,in that direction,theseperation velocity is still directly proportional to approaching velocity. At the same time,the problems of the slanting collsion in two and three-dimention are solved with the method,of decomposition of the solution and their physical meanings in different cases are discussedhere.
