Using models of spatial distribution for four kinds of objects and the latest nuclear physics data of novae (and Type-Ia supernovae) we calculate the flux of (five) γ emission lines and the nuclide abundances they generate. The results show that, as far as the ``physical factor'' is concerned, novae can be one of the main sources of 26Al, but because of the requirements of the nuclide abundances, there is still insurmountable difficulty in nova models. We also point out that investigation of the line profiles will provide important clues to the present problem.
