在本文和后续论文中，我们研究了临界经典流体在不可压缩流动下的稳态特性。当具有频率维数的速度梯度的大小超过临界涨落的平均衰减率时，临界涨落会受到流动的极大影响。在那里，可以预期各种有趣的非线性效应，并将在实验中观察到。这类似于具有流动的聚合物溶液。第一篇文章是关于平均场近似中序参量涨落方差的一般性讨论。
We investigate steady states properties of critical, classical fluids subjected to incompressible flows in this and subsequent papers. Critical fluctuations can be greatly affected by flows when magnitudes of velocity gradients, which have the dimension of frequency, exceed the average decay rate of critical fluctuations. There, various interesting nonlinear effects can be expected and will be observed in experiments. This is analogous to polymeric solutions with flow. The first paper is concerned with some general discussion of the variance of order parameter fluctuations in the mean field approximation.
