利用二维轴对称流体力学程序研究了Rayleigh-Taylor(R-T)不稳定性的起源和发展。在冲击波发生后，观察到了2000 S的蘑菇状结构，并且在H/He界面处开始发展R-T不稳定性。这些结果与Arnett等人的结果有很好的相关性。(1989)数据。研究了SN1987A喷射物中的混合程度以及R-T不稳定性与混合的关系。参考文献36篇。
The origin and development of the Rayleigh-Taylor (R-T) instability is studied using an axisymmetric two-dimensional hydrodynamic code. It is observed that mushroomlike structures appear 2000 s after the blast shock and the R-T instability starts to grow at the H/He interface. These results correlate well with the Arnett et al. (1989) data. The extent of mixing in the ejecta of SN 1987A and the relation between R-T instability and mixing are examined. 36 refs.
