  We have studied the link-integration method for the improved actions. With
this method the $\eta$ parameter in the medium to strong coupling regions is
obtained. Effects of the self-energy terms for the $\eta$ parameters are small
in the regions of $\beta$ and $\eta$ studied. After these investigations, the
anisotropic lattice is used for the calculation of transport coefficients of
the quark gluon plasma.
