摘要：

The explicit expression of the phase of the Bose-Einstein condensates (BEC) is obtained with the expectation value of the quantum operator. With help of this explicit expression, the chemical potential of BEC and the phase diffusion induced by the nonlinear interaction (or two-body dipolar loss) are investigated. This result will helpful to understand the phase properties of the BEG. (C) 2001 Elsevier Science B.V. All rights reserved.
