Structures of Na~+-AD ion-complexes with 1 or 2 H2O molecules were obtained. It was found that H2O can bond with Na~+ in the structure of Na~+-AD to form Na-O van der Waals bond. H2O molecule can also bond with N or O atoms in AD moiety to form H-bonds as N-H…Ow or O…Hw-Ow. The former process takes place more easily. The most stable structures of Na~+-AD ion-complexes with 1 and 2 H2O molecules are W-C7AB and 2W-C7AB, respectively.αB conformer of Na~+-AD can not exist in the presence of 2 H2O molecules.

In the single crystal of C60 with a FCC structure,positron mainly appears outside the C60 molecule.The main annihilation space is the interspace between molecules.The calculated positron bulk lifetime in C60 is 352ps, which agrees with experiment value of 356ps in literature.In carbon nanotube bundles with different dimeters,as the diameter of carbon nanotubes increases,the main space where positron appears changes from the interspace of carbon tubes to the space inside carbon tubes,the radio between positron annihilation with valence eletrons and core eletrons becomes larger,the positron bulk lifetime in carbon nanotube increase rapidly first and come to be a constant at the end.The calculated positron lifetime of carbon nanotube with a dimeter of 0.8～1.6ns is 332～470ps,which agrees with the experiment value of 394ps.Positron annihilation has been studied in widly used compound semiconductors.
