The relations between Bjorken polarized, Bjorken unpolarized and Gross--Llewellyn Smith sum rules

New relations between Bjorken polarized, Bjorken unpolarized and Gross-Llewellyn Smith sum rules are desribed. These relations are valid in the region, where both perturbative series and the series in power-suppressed $1/Q^2$-terms do not yet mahifest the features of asymptotic expansions. The experimentally based considerations support these relations which may surve as the guide for possible in future measurements of the Bjorken unpolarized sum rule at Neutrino Factories.
