Query: Asteroseismology of DAV star EC14012-1446, mode identification and model
  fittings   EC14012-1446 was observed by Handler et al. in April 2004, June 2004, May
2005, and April 2007, and by Provencal et al. in 2008. We review the
observations together and obtain 34 independent frequencies. According to the
frequency splitting and the asymptotic period spacing law, we identify 6 $l$=1
modes, 4 $l$=2 modes, 5 $l$=3 modes, 10 $l$=1 or 2 modes. Grids of white dwarf
models are generated by WDEC with H, He, C, O diffusion in a four-parameter
space. The core compositions are directly from white dwarf models generated by
MESA. The best-fitting model has $M_{*}$=0.710\,$M_{\odot}$, $T_{\rm
eff}$=12200\,K, log($M_{\rm He}/M_{*}$)=-2.5, log($M_{\rm H}/M_{*}$)=-7.0,
log\,$g$=8.261, and $\phi$=3.185\,s. There are 4, 2, and 1 modes identified as
trapped in H envelope for observed $l$=1, 2, and 3 modes, respectively. Trapped
modes jump the queue of uniform period spacing.
