Partonic Picture of Nuclear Shadowing at Small x
  We find that coherent multiple scatterings of the partonic fluctuations of the virtual photon with the nucleons inside the nucleus result in the large nuclear shadowing effect for parton distributions in nuclei. We predict the gluon shadowing effect at small $x$ and for $Q^2\geq 3 GeV^2$.
