In this work , we collected a sample of 69 TeV blazars from TeVCat , obtained their multi-wavelength observations , and fitted their spectral energy distributions by using the second degree polynomial function .
The structure parameters of the synchrotron bumps for 68 blazars and those of the inverse-Compton bumps for 56 blzars are obtained .
Then , we adopted statistical analysis to the parameters ( curvature , peak frequency , peak luminosity , bolometric luminosity , and X/ \gamma -ray spectral indexes ) .
From our analysis and discussions , we can get following conclusions : 1 .
There is a clear positive correlation between the synchrotron peak frequency , \log \nu _ { p } ^ { s } , and the inverse-Compton peak frequency \log \nu _ { p } ^ { IC } , and that between the synchrotron peak luminosity , \log \nu _ { p } ^ { s } L _ { \nu _ { p } } ^ { s } , and the inverse-Compton peak luminosity , \log \nu _ { p } ^ { IC } L _ { \nu _ { p } } ^ { IC } .
2 .
The correlation between the peak frequency and the curvature of synchrotron bump is clearly different from that of the inverse-Compton bump , which further indicates that there are different emission mechanisms between them .
3 .
There is a correlation between \log \nu _ { p } ^ { IC } and \gamma -ray spectral index , \alpha _ { \gamma } , for the TeV blazars : \log \nu ^ { IC } _ { p } = - ( 4.59 \pm 0.30 ) \alpha _ { \gamma } + ( 32.67 \pm 0.59 ) , which is consistent with previous work of Abdo et al . ( 2010 ) .
4 .
An ” L-shape ” relation is found between \log \nu ^ { s } _ { p } and \alpha _ { X } for both TeV blazars and Fermi blazars .
A significant correlation between \log \nu ^ { s } _ { p } and X-ray photon index ( \alpha _ { X } ) is found for the TeV blazars with high synchrotron peak frequency : \log \nu ^ { s } _ { p } = - ( 3.20 \pm 0.34 ) \alpha _ { X } + ( 24.33 \pm 0.79 ) , while the correlation is positive for low synchrotron peaked TeV sources .
5 .
In the \alpha _ { X } - \alpha _ { \gamma } diagram , there is also an ” L-shape ” , the anti-correlation is consistent with the available results in the literature , we also find a positive correlation between them .
6 .
Inverse-Compton dominant sources have luminous bolometric luminosities .
