摘要：

The behavior of power spectra in a Rayleigh-Bénard convection experiment in a helium-gas cell is reported. The high-frequency part of the data for all Rayleigh numbers from 7×106 to 4×1014 is fit by a single functional form, obtained by a natural generalization of a multifractal analysis. Low-frequency data cannot be fit in this form. © 1990 The American Physical Society.
