通过扩展Clever和Busse（1974）对流卷数值稳定性分析的参数范围，发现了一种新的不稳定性，在低普朗特数流体中，这种不稳定性称为斜变不稳定性，它导致对流卷的波长随Rayleigh数的增加而增加。理论计算结果与实验结果的比较表明，两者吻合较好。
By extending the parameter range of the previous numerical stability analysis of convection rolls (Clever and Busse, 1974) a new instability has been found. In low Prandtl number fluids this instability, called the skewed varicose instability, causes an increase of the wavelength of convection rolls with increasing Rayleigh number. A comparison between theoretical results and experimental observations shows good agreement.
