In the storage rings and traditional cyclic accelerators the obtaining of the beam polarization is hampered at high energies by depolarization effects connected mainly with the energy dependence of a spin precession frequency. In this work the ways of controlling this dependence are considered, using additional fields introduced into straight sections. In particular, use of spin flips around the directions in the orbit plane allows elimination of the energy dependence of the effective pression frequency. Possible schemes providing the conservation of polarization during acceleration are presented. Under stationary conditions for electrons and positrons it is possible to suppress substantially the depolarizing influence of quantum energy fluctuations during radiation by using the method of spin flips in straight sections.
