2014我们在这里提出了一个推广的Boussinesq近似感兴趣的热流体动力学研究的水平流体层加热从下面（瑞利-贝纳德问题）时，该层的深度是重要的。一个简单的量纲分析的问题表明，在何种条件下不能忽略，无论多么小，等温压缩性。我们还讨论了粘性耗散和绝热温度梯度所起的作用。托姆37 No 3 Mars 1976
2014 We present here a generalization of the Boussinesq approximation of interest in the thermohydrodynamic study of a horizontal fluid layer heated from below (Rayleigh-Bénard problem) when the depth of the layer is important. A straightforward dimensional analysis of the problem shows under which conditions one cannot neglect, however small, the isothermal compressibility. We discuss also the role played by viscous dissipation and by an adiabatic temperature gradient. Tome 37 No 3 Mars 1976
