Abstract
|
The research work relevant to the newly established Chinese Solar
Radio Broadband Fast Dynamic Spectrometers is reviewed. With the help
of these new instruments many fine structures of solar radio bursts
have been observed in very high temporal and spectral resolutions,
e.g., the bi-directional type-III bursts in microwave, the microwave
type-U bursts in sub-second time duration, microwave type-M bursts,
evolving emission lines in microwave and multiple twisted type-U
bursts first observed in such high frequency range, etc. It is
expected that these new instruments may play an important role in the
23rd solar cycle maximum research. |
