摘要：

Exact expectation values of the fields e(alpha phi) in the Bullough-Dodd model are derived by adopting the "reflection relations" which involve the reflection S-matrix of the Liouville theory, as well as a special analyticity assumption, Using this result we propose explicit expressions far expectation values of all primary operators in the c < 1 minimal CFT perturbed by the operator Phi(1,2) or Phi(2,1). Some results concerning the Phi(1,5) perturbed minimal models are also presented. (C) 1998 Elsevier Science B.V.
