摘要	A group of centimetric spikes was detected during the burst of 10 March 2002 with the spectrometer of NAOC ( National Astronomical Observatories of China). These centimetric spikes are resolved clearly in the time and frequency panels. A statistical analysis shows that these spikes have very short durations (5-10 ms), narrow bandwidths (20-40 MHz), very high polarization degrees (greater than or equal to90%), and relatively weak flux densities (10-40 sfu). The simultaneous 2D image observations of NoRH (Nobeyama Radioheliograph) and SSRT (Siberian Solar Radio Telescope) imply that the spikes should come from a small source region, which was located in an area with a complex magnetic field. It is also found that the spikes are polarized in the X-mode. These observations suggest that the electron cyclotron maser (ECM) is the most likely mechanism of these centimetric spikes.
