摘要：
A hybrid model that allows one to interpolate between the (original) Regge approach and dynamical triangulation is introduced. The gained flexibility in the measure is exploited to study dynamical triangulation in a fixed geometry. Our numerical results support KPZ exponents, A critical assessment concerning the apparent lack of gravitational effects in two dimensions follows.
