Fine Radio Solar Structures of Super-High Temporal Resolution and Associated Solar Activities

After Oct. 2004, a new observation mode has come into operation for our radio spectrometer (Huairou, Beijing) which has a super-high temporal resolution of 1.25ms in the frequency range of 1.10-1.34GHz. The spectral resolution is 4MHz. We report here three solar radio events observed with the new mode. The images show their spikes, fish groups, and overlapping fine structures (FS). At about 8-14min after those radio FSs, there were associated type II meter-wave bursts (traces of coronal shock waves) detected for all three events. Also detected were CMEs (Coronal Mass Ejections) were associated with these shock waves.
