论文摘要
无需微调就研究了巨大身体的高能量碰撞。我们研究了重力结合系统中两个球形同心壳的多次碰撞，并计算壳之间的质量能量中心。我们求解两个壳的运动方程，而不会对初始参数进行任何微调。在这个结合的系统中，壳体多次碰撞，由于壳的混乱行为，这些运动是高度不平凡的。因此，每次碰撞的质量能量中心都在非试验上变化，甚至达到其理论上的上限。我们确认，在多次碰撞过程中无需微调即可自动实现理论极限的很大一部分。同时，我们还研究了一些碰撞后从系统中研究的壳弹药。如果初始壳的能量足够大，那么多次碰撞可能会导致一个壳积累能量，以使其逃到无穷大，即使最初有两个壳被限制在系统中。弹出是由多次碰撞引起的，导致壳之间的非平凡能量转移。还讨论了最大质量能量中心与导致壳弹出的能量转移之间的关系。
High energy collision of massive bodies is investigated without fine tuning. We study multiple collisions of two spherical concentric shells in a gravitationally bound system and calculate the center of mass energy between the shells. We solve the equation of motions for two shells without imposing any fine tuning of the initial parameters. In this bound system, the shells collide many times and these motions are highly nontrivial due to chaotic behavior of the shells. Consequently, the center of mass energy for each collision varies nontrivially and even reach almost its theoretical upper limit. We confirm that a significant proportion of the theoretical limit is automatically achieved during multiple collisions without fine tuning. At the same time, we also study shell ejection from the system after some collisions. If the initial shell's energy is large enough, multiple collisions may cause one shell to accumulate energy so that it escapes to infinity, even though two shells are initially confined in the system. The ejection is caused by multiple collisions inducing nontrivial energy transfer between the shells. The relation between the maximum center of mass energy and the energy transfer causing the shell ejection is also discussed.
