摘要/Abstract

摘要： 首先对惯性约束聚变(ICF)遇到的流体力学界面不稳定性作了简要的分析;其次讨论了Rayleigh-Taylor(RT)不稳定性在ICF中所起的作用;第三,根据一维数值计算结果,按照考虑密度梯度和烧蚀致稳的RT不稳定性增长的定标规律对不稳定性增长作了估计。最后在计算结果的讨论中,对有关实验测量提出某些倾向性的建议。

Abstract: The hydrodynamic surface instabilities driven by X-ray ablation in Inertial Confinement Fusion(CIF)have been analyzed,and the role of Raleigh-Taylor(RT) instabilities in CIF has been also discussed.Based on one dimension numerical computational results,according to the formula of net growth factor at the ablation surface,the net growth rates of RT instabilities have been estimated.Finally,some recommendations for instability experiment are proposed.

Key words: hydrodynamic surface instability, Rayleigh-Taylor instability, radiation ablation
