摘要：

High-wave-number modes are eliminated in a band characterized by its width parameter-lambda in k space. The requisite conditional average is evaluated as an approximation in which coupling effects are neglected to order-lambda 2, for small-lambda. A fixed point was found under renormalization-group transformation, which corresponded to the Kolmogorov "- 3/5" spectrum with spectral constant-alpha = 1.60.
