星风环境下,减速时标以内时平降阶段,拐折是减速时标。
(这个也可以用来限制洛伦兹因子哦~ 就和光学的peak是一样的,不过要是发现有几个光学的peak和这个时标不一致就麻烦了,不过也可以说光学的是别的来源。)

Abstract
We investigate the shallow decay phase of an early x-ray afterglow in gamma-ray bursts discovered by Swift, and suggest that both the shallow decay phase and the normal phase are from external shock in a wind environment, while the transferring time is the deceleration time. We apply this model to GRBs 050319 and 081008, and find that they can be explained by choosing a proper set of parameters.
