本文用解析方法研究了垂直缝内自然对流导热区的稳定性。对于Pr < 12.7 the instability sets in as horizontal stationary cells. The critical Grashof number is nearly independent of Prandtl number. For Pr>12.7，不稳定性以行波的形式出现。随着普朗特数的增加，发病的不稳定性接近正确的限制解决方案，这是恒定的GrPr 1 - 2的函数。
The stability of the conduction regime of natural convection in a vertical slot has been studied analytically. For Pr< 12.7 the instability sets in as horizontal stationary cells. The critical Grashof number is nearly independent of Prandtl number. For Pr> 12.7 the instability sets in as a travelling wave. As the Prandtl number is increased the onset of instability approaches the correct limiting solution which is constant as a function of GrPr 1 2.
