摘要
本文描述了原始盘中螺旋冲击的非线性结果。对于大多数原始盘条件，螺旋冲击会在冲击后区域导致垂直力失衡，并使气体沿盘面垂直于盘中线快速膨胀。这种膨胀具有类似于不可压缩流体中液压跌落的特征。我们提出了描述这些混合型现象（冲击液压跌落）行为的理论模型，并将其与三维水动力学模拟进行比较。我们讨论了冲击液 hydraulic跌落所产生的完全三维冲击结构，并探讨了这些结构对盘中混合、湍流以及固体演化的可能影响。

备注
39 pages, 18 figures, 1 table. Edited to match as closely as possible the ApJ proofs, which resulted in the correction of several typos. In addition, section 5.3 was slightly altered because an error in an analysis tool was discovered; the differences between the entropy gradient method and the Schwarzschild criterion method are minor. Figure 18 now only includes what was Figure18a
