The flare productive region NOAA 930 on solar disk at S05W33 location produced an X3.4/4B flare at 02:40 UT on 13 Dec 2006. The complicated radio bursts with a 44000 SFU at 10 cm wavelength, Type II burst with shock speed of 1534 km/s and Type IV radio sweeps were associated with this event, as well as a fast moving CME with estimated projected speed of 1500 km/s. Very rich complicated radio fine structures including spikes, zebra patterns and spiky zebra features, narrow type III bursts, pulsations and periodic pulsation structures, fibrils and rope-like stripes, mixed fast and slow drifting stripes, etc., were observed during the long period from 02:20 to 05:10 UT by the spectropolarimeters in 1-2 GHz, 2.6-3.8 GHz and 5.2-7.6 GHz at NAOC/Huairou with very high temporal (1.25-8ms) and spectral (4-20 MHz) resolutions. Combined with Huairou magnetograph observations, TRACE EUV images, RHESSI HXR observations and STEREO low frequency observations, the associations of these radio fine structures and the flare/CME processes are analyzed so as to understand the physical nature of the observed phenomena.
