摘　　要：It is argued that the longitudinal part of space-like photon in its Breit frame is unable to transform into vector meson.Starting from this argument and adding a small amount of diquark component into the nucleon structure functions in nuclei,the A dependence of the R_(A)=σ^(A)_(L )/σ^(A)_(T) value observed in electron nucleus DIS by the SLAC Group is explained.
