摘要：

The finite-size effects of the dynamical structure factors in the XXZ-model are studied in the euclidean time (tau-) representation. Away from the critical momentum p = pi finite-size effects turn out to be small except for in large-tau limit. The large finite-size effects at the critical momentum p = pi Signal the emergence of infrared singularities in the spectral (omega-) representation of the dynamical structure factors.
