王宁 %A 刘秉正 %A 安刚 %J 生物物理学报 %D 1996 %I %X We analyze the time series of electrogastrogram(EGG) signals with power spectrum method and nonlinear dynamical method. We calculate the correlation dimension and the largest Lyapunov exponent to characterize it.The power spectrum of EGG is continuous with a peak, the correlation dimension is between 6 and 7, and the largest Lyapunov exponent is a positive number. So we conclude that EGG signals are not stochastic noise, but obey certain deterministic law. %K EGG Time delay Correlation dimension The largest Lyapunov exponent
