Observations and Research on the Solar Radio Spectrum at Yunnan Observatory

In this paper the performances and the main observational results, including the identification of meterw ave blips, 10 milliseconds coronal quasi-oscillations, the size distributions of the spikes' sources and the electron density determination of coronal condensation by the solar eclipse, by the solar radio meter-wave spectrograph at the Yunnan Observatory are introduced.This instrument is made based on the principle of the spectral analysis of the acousto-optic deflection. The spectral resolution is 0.25 MHz and the time resolution is promoted from 80 ms to l ms.
