Abstract
Li (Phys. Rev. Lett. {\bf 69},1819 (1992)) has computed the current-voltage characteristics (CVC) of a disordered two-dimensional (2D) Josephson-junction array and claimed that his data(nonlinear CVC for small temperatures), gives evidence for a finite-temperature phase transition in the 2D gauge-glass model in contradiction to the result of equilibrium simulations. In this Comment I show that the nonlinear CVC, found by Li, is merely a single-junction effect.
