AI 中文摘要
我们引入一种数值技术，用于从已知相空间分布的球对称自洽模型出发，实现轴对称和三轴自引力系统的N体实现。该方法是对所谓绝热压缩技术的改进，能更好地控制粒子分布的有效椭率，生成可作为N体模拟非球形初始条件的位力化系统，文中还给出并讨论了一些数值稳定性测试。
英文摘要
We introduce a numerical technique to implement $N-$body realizations of axisymmetric and triaxial self-gravitating system starting from a spherical self-consistent models for which a phase-space distribution is known. The method is an improvement of the so-called adiabatic squeezing technique and allows one to have a better control of the effective ellipticities of the particle distribution and produces virialized systems that can be used as non-spherical initial conditions for $N-$body simulations. Some numerical stability tests are presented and discussed.
