摘要：
A method has been developed for obtaining equivalent linear two-body (ELTB) equations for the system of many (N) bosons using the variational principle. The method has been applied to the one-dimensional N-body problem with pair-wise contact interactions (McGurie-Yang N-body problem) and to the dilute Bose-Einstein condensation (BEC) of atoms in anisotropic harmonic traps at zero temperature. For both cases, it is shown that the method gives excellent results for large N. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
