3. In the study of the lagrange stability of impact motion , we give some conditions of the bouncing solution of the asymptotically linear equation which is bounded or unbounded . outside of a large disc , using the symplectic transformation of the hamilton system to estimate the iteration of the successor map . applying the moser ' s small twist theorem , we get the invariant curves and then give the proof of the bouncing solutions which is bounded
在碰撞运动的lagrange稳定性的讨论中，给出了渐近线性方程碰撞解有界或无界的条件，在充分大的圆盘外，通过hamilton系统的辛坐标变换的角度平均来估计后继映射的迭代，应用moser小扭转定理得到不变曲线从而给出在一定条件下碰撞解有界的证明，碰撞解无界性的证明将采用直接估计后继映射的方法给出。
