我们估计了硅酸盐蒸气从巨撞击形成的盘中逃逸的判据。从盘逃逸影响盘的质量分布和比角动量。我们将结果应用于月球形成撞击形成的圆盘。在热（>6000 K）和高度蒸发（>63%）的盘的情况下，罗氏半径之外的材料逃逸。这表明月球的形成受到巨大撞击后盘的热状态的影响。
We have estimated a criterion for escape of silicate vapor from the disk formed by a giant impact. Escape from the disk affects the mass distribution and specific angular momentum of the disk. We applied the results to the disk formed by the Moon-forming impact. In the case of a hot (>6000 K) and highly vaporized (>63%) disk, the material outside of the Roche radius escapes. This indicates that the formation of the Moon is influenced by the thermal state of the disk just after the giant impact.
