摘要：

We obtain exactly the vacuum expectation values [(partial derivative phi)(2) (partial derivative phi)(2)e(i alpha phi)] in the sine-Gordon model and (L-2 (L) over bar(-2) Phi(l,k)) in Phi(1,3) perturbed minimal CFT. We discuss applications of these results to short-distance expansions of two-point correlation functions. (C) 1999 Elsevier Science B.V.
