  Three types of microscopic nucleus-nucleus optical potentials are constructed
using three patterns for their real and imaginary parts. Two of these patterns
are the real $V^H$ and imaginary $W^H$ parts of the potential which reproduces
the high-energy amplitude of scattering in the microscopic Glauber-Sitenko
theory. Another template $V^{DF}$ is calculated within the standard
double-folding model with the exchange term included. For either of the three
tested potentials, the contribution of real and imaginary patterns is adjusted
by introducing two fitted factors. An acceptable agreement with the
experimental data on elastic differential cross-sections was obtained for
scattering the $^{16, 17}$O heavy-ions at about hundred Mev/nucleon on
different target-nuclei. The relativization effect is also studied and found
that, to somewhat, it improves the agreement with experimental data.
