The microwave zebra pattern is the most interesting, intriguing, and complex spectral structure frequently observed in solar flares. A comprehensive statistical study will certainly help us to understand the formation mechanism, which is not exactly clear now. This work presents a comprehensive statistical analysis of a big sample with 202 zebras events collected from observations at the Chinese Solar Broadband Radio Spectrometer at Huairou and the Ondřejov Radiospectrograph in the Czech Republic at frequencies of 1.00–7.60 GHz from 2000 to 2013. After investigating the parameter properties of zebras we find that the variation of zebra stripe frequency separation with respect to frequency is the best indicator for a physical classification of zebras.
