摘要：

We present optical spectra of the Type Ic supernova 1994I in M51 and preliminary non-local thermodynamic equilibrium (non-LTE) analysis of the spectra. Our models are not inconsistent with the explosions of C+O cores of massive stars, While we find no direct evidence for helium in the optical spectra, our models cannot rule out small amounts of helium. More than 0.1 M(.) of helium seems unlikely.
