Shallow decay phase of the early X-ray afterglow from the external shock
  in wind environment
  The shallow decay phase of the early X-ray afterglow in gamma-ray bursts
discovered by {\it Swift} is a widely discussed topic. As the spectral index
does not change at the transferring of the shallow decay phase to a normal
phase, it implies this transferring should be a dynamical change rather than a
spectral evolution. We suggest both the shallow decay phase and the normal
phase are from the 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 them can be well explained by choosing a proper set of parameters.
