摘要：

The quotient field of the ring of invariants of a rational G(a) action on C(n) is shown to be ruled. As a consequence, all rational G(a) actions on C4 are rationally triangulable. Moreover, if an arbitrary rational G(a) action on C(n) is doubled to an action of G(a) x G(a) on C2n, then the doubled action is rationally triangulable.
