| Abstract: | In this paper we calculate the correlation dimensions, entropies, and the largest Lyapunov exponents of homogeneous furbulence signals by making use of the technique of phase space reconstruction with delay coordinates. The results show that this is a kind of deterministic chaos perturbed by the random noise, its underlying attractor is a strange attractor with the background of random noise. |
