摘要：
Based on considerations in conformal gauge I derive up to nextleading order a relation between the coefficients of beta-functions in 2D renormalizable field theories before and after coupling to quantized gravity. The result implies a coupling constant dependence of the ratio of both beta-functions beyond leading order.
