摘要：
The super 0-brane and GS superstring actions on AdS(2) x S-2 background with 2-form flux are constructed by taking a supercoset approach. We find that the super 0-brane action contains two parameters which are interpreted as the electric and magnetic charges of the super 0-brane. The obtained super 0-brane action describes the BPS saturated dyonic superparticle moving on AdS(2) x S2 background. The WZ action contains the required coupling with 2-form flux. For GS superstring, we find the string action on AdS(2) x S-2 takes the same form as those in AdS(3) x S-3 and AdS(5) x S-5 with RR field background. (C) 1999 Elsevier Science B.V.
