摘要：
The power-law energy spectra of non-thermal electrons for each 1.024 second have been drawn together during the flare. For some flares, it is discovered that the energy spectra taken at different times present a roughly fixed crossing point, at which point the flux of non-thermal electrons keeps the same during the flare. The possible significance of this phenomenon is discussed. We conjecture that there may be a flux saturation at the low-energy cutoff in the process of electron acceleration.
