Identifying AGN's Balmer-Absorptions and stratified NLR kinematics in
  SDSS\.J112611.63+425246.4
  Balmer absorption is a rare phenomenon in active galactic nuclei (AGNs). So
far, only seven Balmer-absorption AGNs have been reported in literature. We
here report the identification of SDSS\,J112611.63+425246 as a new
Balmer-absorption AGN through our spectral analysis, and study the kinematics
of its narrow emission-line region (NLR). We model the continuum by a linear
combination of a starlight component, a powerlaw from the central AGN and the
emission from the FeII complex. After the subtraction of the modeled continuum,
each emission/absorption line is profiled by a sum of multi Gaussian functions.
All the line shifts are determined with respect to the modeled starlight
component. By using the host starlight as a reference for the local system,
both H$\alpha$ and H$\beta$ show AGN's absorptions with a blueshift of
$\sim300\mathrm{km\ s^{-1}}$. We identify a strong anti-correlation between the
inferred velocity shifts and ionization potential for various narrow emission
lines, which suggests a stratified NLR kinematics. A de-accelerated outflow is
implied for the inner NLR gas, while an accelerated inflow for the outer NLR
gas. This complicated NLR kinematics additionally implies that AGN's narrow
emission lines, even for the low-ionized lines, might not be a reliable
surrogate for the velocity of the local system.
