摘要：

We calculate the vacuum expectation values of local fields for the two-parameter family of integrable field theories introduced and studied by Fateev [Nucl. Phys. B 473 (1996) 509]. Using this result we propose an explicit expression for the vacuum expectation values of local operators in parafermionic sine-Gordon models and in integrable perturbed SU(2) coset conformal field theories.
