  The experimental data of the magnetic dipole moment(MDM) of lepton($e$,
$\mu$) is very exact. The deviation between the experimental data and the
standard model prediction maybe come from new physics contribution.
  In the supersymmetric models, there are very many two loop diagrams
contributing to the lepton MDM. In supersymmetric models, we suppose two mass
scales $M_{SH}$ and $M$ with $M_{SH}\gg M$ for supersymmetric particles.
Squarks belong to $M_{SH}$ and the other supersymmetric particles belong to
$M$. We analyze the order of the contributions from the two loop diagrams. The
two loop triangle diagrams corresponding to the two loop self-energy diagram
satisfy Ward-identity, and their contributions possess particular factors. This
work can help to distinguish the important two loop diagrams giving corrections
to lepton MDM.
