本文以620个BL - Lac为样本，计算了光子的平均能量，讨论了同步加速器峰值频率的对数与光子平均能量的关系。结果表明，BL - Lac物体的光子能量与同步加速器峰值频率之间存在正相关关系，这意味着射线发射与射电至x射线波段的低能发射有关，高能射线发射仅部分来自同步加速器自康普顿过程（SSC）。
In this paper, the average energy of the-photon () is calculated and the correlation betweenand the logarithm of the synchrotron peak frequency () is discussed for a sample of 620 BL Lac objects. The results show that there exists a positive correlation between the-photon energy and the synchrotron peak frequency for BL Lac objects, which implies that the-ray emissions are related to the low-energy emissions of radio to X-ray bands, and the high energetic-ray emissions are only partially from the synchrotron self-Compton process (SSC) for BL Lac objects.
