我们提出了一个简单的精确公式，在二维湍流的三点速度相关函数，这是有效的，在所有尺度和直接和逆级联制度之间的插值。正如预期的那样，这些相关函数在这些极端状态下是通用的。我们还讨论了各向异性和摩擦的影响。
We present a simple exact formula for three-point velocity correlation functions in two-dimensional turbulence which is valid at all scales and which interpolates between the direct and inverse cascade regimes. As expected, these correlation functions are universal in these extreme regimes. We also discuss the effects of anisotropy and friction.
