英文摘要	A broadband solar radio spectrometer with a bandwidth of about 7 GHz has been developed in China for solar maximum 23. This work is a cooperative project of Beijing Astronomical Observatory (BAO), Purple Mountain Observatory (PMO), Yunnan Observatory (YNO), and Nanjing University. The spectrometer of PMO worked in the waveband of 4.5-7.5 GHz, that of BAO in 1-2 GHz,2.6-3.8 GHz, and 5.2-7.6 GHz, and that of YNO in 0.7-1.5 GHz. The spectrometer of PMO is a multichannel and frequency-agile one with a time resolution of 1-5 ms and a frequency resolution of 10 MHz. It started to operate in August 1999 and since then more than 300 spectral events have been observed, and some type III or type III-like structures have also been found. In this paper, some selected typical events, for example, the events on 25 August 1999 and 27 October 1999, are presented, and some new observed features are also described and discussed.
