  The ordering of a multilayer consisting of DSPC bilayers on a silica sol
substrate is studied within the model-independent approach to the
reconstruction of profiles of the electron density from X-ray reflectometry
data. It is found that the electroporation of bilayers in the field of anion
silica nanoparticles significantly accelerates the process of their saturation
with Na+ and H2O, which explains both a relatively small time of formation of
the structure of the multilayer of 10^5 - 7x10^5 s and ~13 % excess of the
electron density in it.
