摘要：

We present a method to calculate explicitly the partition function of a one-dimensional delta -function bose gas. The cluster integrals are obtained for up to the four particles and are shown to be the same as those by the thermal Bethe ansatz method (TBA). (C) 2001 Elsevier Science Ltd. All rights reserved.
