| 摘 要： | We have collected 18γ-ray-loud BL Lac with observed data in multiwavedand,we find that γ-ray flux densities correlate better with the near-IR flux densities than those with the optical or x-ray flux densities.There is no correlation between γ-ray and radio flux densities.Possible constraints on the γ-ray emission mechanism are discussed.We suggest that the main γ-ray radiation mechanism is probably the synchrotron self-Compton process.The inverse Compton scattering of the radiation from hot circumscribe dust.by beamed ultrarelativistic electrons,is likely to be an important complementary mechanism.
