Abstract
In this paper we have extended the uncertainty relations to mixed states fo r some special cases of quantum oscillators, relations which are calculated for this kind of states by means of the earlier established virial and Hel lmann-Feynman theorems. The lower bound of these uncertainty relations is e stimated for a few exactly solvable potentials, too.
