伽马射线暴(伽马射线暴)和耀星都有相对论喷流从我们的视线指向一个小角度。最近的几项研究表明，这两种来源可能具有相似的喷流物理特征。在这项工作中，我们从整体上探讨了伽玛暴和耀星的可变性。我们发现，最小变率时间尺度(MTS)与洛伦兹因子伽马之间的相关性，只有Sonbas等人在伽玛暴中才能发现。可以扩展到具有MTS的联合相关性的运动衫。Alpha Gamma(-4.7+/-0.3)。同样的道理也适用于MTS。L-伽马(-1.0+/-0.1)。在伽玛暴中发现的相关性，也可以很好地扩展到blazar。这些结果进一步证明，这两种来源的喷流是相似的，尽管它们的中心发动机的质量尺度非常不同。需要进一步研究这些关联的物理起源，这可以揭示喷流物理的本质。
Both gamma-ray bursts (GRBs) and blazars have relativistic jets pointing at a small angle from our line of sight. Several recent studies suggested that these two kinds of sources may share similar jet physics. In this work, we explore the variability properties for GRBs and blazars as a whole. We find that the correlation between minimum variability time-scale (MTS) and Lorentz factor, Gamma, as found only in GRBs by Sonbas et al. can be extended to blazars with a joint correlation of MTS. alpha Gamma(-4.7 +/- 0.3). The same applies to the MTS. L-gamma(-1.0 +/- 0.1). correlation as found in GRBs, which can be well extended into blazars as well. These results provide further evidence that the jets in these two kinds of sources are similar despite of the very different mass scale of their central engines. Further investigations of the physical origin of these correlations are needed, which can shed light on the nature of the jet physics.
