Using the dilaton scalar and axion pseudoscalar fields we construct a number of scalars and differential forms which are symmetric under the -subgroup of the group . These invariants enable us to establish various 10-dimensional invariant actions. Other invariants which are not independent from the previous ones will be detached.
