英文摘要	We present a strong correlation of the gamma-ray (above 100 MeV) mean spectral indices alpha gamma and X-ray (1keV) mean spectral indices alpha (X) for 34 gamma-ray-loud blazars (16 BL Lac objects and 18 flat spectrum radio quasars). A strong correlation is also found between the gamma-ray flux densities F-gamma and X-ray flux densities F-X in the low state for 47 blazars (17 BL Lac and 30 flat spectrum radio quasars). Possible correlation on the gamma-ray emission mechanism is discussed. We suggest that the main gamma-ray radiation mechanism is probably the synchrotron process. The gamma-ray emission may be somewhat different from that of BL Lac objects and flat spectrum radio quasars.
