  First,we consider a cyclic cubic order generated by a unit.We explain when the order is invariant under the action of Galois group and determine a system of fundamental units of the order.Next,we talk about a cyclic cubic order generated by an algebraic integer and its conjugates.This is a joint work with St′ephane R.Louboutin.
