摘要

We present very simple non-integral relations between deep inelastic structure functions $F_L$ , $F_2$ and the gluon distribution at small $x$ based on perturbative QCD which are useful for the phenomenological analysis of data at low $x$ . As an application we extract the deep inelastic scattering cross-sections ratio $R= \sigma_L/\sigma_T$ in the range $10^{-4} \leq x \leq 10^{-2}$ from $F_2$ HERA data.
