An analysis of the temporal properties of a group of spikes in the solar flares is presented recorded by the 1–2 GHz spectrometer of National Astronomical observatories of China (NAOC) on 27 October 2003. The time profile of each single spike was fitted and analyzed. In particular, we determine the e-folding rise and decay times corresponding to the ascending and decaying parts of the time profile, respectively. Several important correlations have studied and compared with the results in earlier literature, i.e. those between duration and frequency, e-folding rise time and decay time, e-folding decay time and duration, and e-folding decay time and peak flux. Plasma temperatures of source region are also estimated and the possible decaying mechanism is discussed.
