本文回顾了最近的努力来描述复杂的模式，在各向同性流体（瑞利-贝纳德对流）以及各向异性液晶（电流体动力对流）时，远离平衡。一个数值方案，用于解决全流体动力学方程，允许令人惊讶的是，以及与实验的详细比较。该方法也可以是有用的模型（序参数方程）的系统建设。(c)1996年美国物理学会。
This paper reviews recent efforts to describe complex patterns in isotropic fluids (Rayleigh-Benard convection) as well as in anisotropic liquid crystals (electro-hydrodynamic convection) when driven away from equilibrium. A numerical scheme for solving the full hydrodynamic equations is presented that allows surprisingly well for a detailed comparison with experiments. The approach can also be useful for a systematic construction of models (order parameter equations). (c) 1996 American Institute of Physics.
