利用直接数值模拟研究了由浮力产生的运动引起的分子扩散和搅拌引起的两种不同密度的纯流体的非均匀混合物的均匀化，如Rayleigh-Taylor（RT）不稳定性。施密特数Sc以20的因子变化，0.1
The homogenization of a heterogeneous mixture of two pure fluids with different densities by molecular diffusion and stirring induced by buoyancy-generated motions, as occurs in the Rayleigh-Taylor (RT) instability, is studied using direct numerical simulations. The Schmidt number, Sc, is varied by a factor of 20, 0.1
