摘要：
A new form of the Wilson renormalization group equation is derived in which the flow equations are, up to linear terms, proportional to a gradient flow. A set of coordinates is found in which the flow of marginal, low-energy, couplings takes a gradient form, if relevant couplings are tuned to vanish.
