论文摘要
近年来，快速无线电爆发（FRB）的总可用样本一直在稳步增长，从统计的角度促进了FRB的研究。同时，FRB的分类目前是当务之急。我们建议爆发的亮度温度可以作为分类的理想标准。在这项工作中，我们收集了所有局部FRB的可用数据，并发现固有的脉冲宽度和爆发能量之间存在正相关，$ t _ {\ rm i} \ proptoe_ν^{0.25} $，对于三个重复的FRB，与我们先前使用FRB 20121102A数据相似的FRB类似。关键行$ t _ {\ rm b，cri} $在不同的FRB中有所不同，这可能反映了源属性的差异。这种关系可以对主流辐射机制构成强烈限制。显然，连贯的曲率辐射或同步加速器maser辐射都无法达到重现这种关系所需的高亮度温度。
The total available sample of fast radio bursts (FRBs) has been growing steadily in recent years, facilitating the study of FRBs from a statistical point of view. At the same time, the classification of FRBs is currently an imperative issue. We propose that the brightness temperature of bursts can serve as an ideal criterion for classification. In this work, we gather the available data for all localized FRBs and we find a positive relation between the intrinsic pulse width and burst energy, $T_{\rm i}\propto E_ν^{0.25}$, for three repeating FRBs that is similar to that of our previous work using FRB 20121102A data alone. The critical line $T_{\rm B,cri}$ is found to vary for different FRBs, which may reflect the differences in source properties. This relation can put strong constraints on mainstream radiation mechanisms. It is evident that neither the coherent curvature radiation or synchrotron maser radiation have the capability to reach the high brightness temperature required to reproduce this relation.
