数值研究了一维自引力系统的长时间行为。发现了准平衡点之间的游动行为，并阐明了其根源。准平衡的宏观分布不同于等温分布，但在两个连续的准平衡之间出现的瞬态类似于等温分布。平均的是巡回给出近似的热平衡。
Long time behavior of one-dimensional self-gravitating system is numerically investigated. Itinerant behavior among quasiequilibria is discovered, and its origin is clarified. The macroscopic distributions of the quasiquilibria are different from the isothermal distribution, but the transient states, which appears between two successive quasiequilibria, resemble the isothermal distribution. Averaging over the is itinerancy gives approximately the thermal equilibrium.
