摘　　要：介绍了围绕我国近年完成的太阳射电宽带动态频谱仪展开的研究工作进展，并提出了今后的努力方向，以期该设备能在我国第２３周太阳活动峰年研究中发挥更大作用．The research work relevant to the newly established Chinese Solar Radio Broadband Fist 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 hi-directional type-ill 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.
