为了更好地理解烧蚀瑞利-泰勒（RT）不稳定性，要测量的最重要的量之一是RT不稳定性显着降低的短波长区域中的增长率。利用创新的云纹干涉法首次测量了直接驱动靶的短波长（4.7-12微米）RT生长速率[M. Matsuoka等人，Rev. Sci.仪器。70，637（1999）]。通过求解非局部热传输的福克-普朗克方程的模拟，这些增长率得到了相当好的再现。
One of the most important quantities to be measured for better understanding of the ablative Rayleigh-Taylor (RT) instability is the growth rate in the short wavelength region at which the RT instability is significantly reduced. The short wavelength ( 4.7-12 microm) RT growth rates for direct-drive targets were measured for the first time by utilizing the innovated moiré interferometry [M. Matsuoka et al., Rev. Sci. Instrum. 70, 637 (1999)]. These growth rates were reasonably well reproduced by the simulation that solves the Fokker-Planck equation for nonlocal heat transport.
