摘要：

The ground state properties of a Bose-Einstein condensate with repulsive or attractive interatomic interaction confined in axially symmetric magnetic trap are studied through the variational approach. It is shown that; if the trap has a high asymmetry and thus the equi-potential surface of the trap is of "cigar" or "pancake" shape, the properties of the condensate are drastically changed from the case of isotropic (spherically symmetric) trap.
