Based on the present theoretical status of the phase transitiovt of the 2d-Heisenberg system, we re-examined in the anisotropic 2d-Ileisenberg system thecrossing-over from the 2d-Ising to the 2d-Heisenberg class for the amzplitude of thespecific heat capacity and the coefficient of the inverse correlation 1e?tgth in termsof the weak universality. It is clarified that in the anisotropy region J=0.002N1the system follows the strong universality. However, near A =0 the s.ystem shouldfolloxv the weak universality in connection with the characteristic behavior ofthe temperature dependence of the correlation length in the 2?d-Heisenbergsystem.
