摘要：

Electron temperature fluctuations seen in a magnetically confined tokamak plasma have some of the characteristics of the avalanchelike events sometimes associated with self-organized criticality, including intermittency large space and time scales, "1/f" spectra, large tails in the autocorrelation function, and clear evidence of radial propagation.
