The scaling variables in the theory of the interacting disordered system are interpreted in terms of the quasiparticle density of states and diffusion constant, and Fermi-liquid interaction parameters. In the absence of spin-flip or spin-orbit scattering, the scaling theory valid to first order in the disorder is interpreted and a general description of possible scaling scenarios is given.
