In Russia the interesting work Babadjanov P. B. was published, in which
outburst of activity Quadrantid were explained by waves of a density of
meteoroids. These waves of a heightened density periodically can arise
because of perturbations Jupiter, in old meteor showers. Probably, in SDA a
similar situation. Babadjanov modeled dummy meteoroids, on a uniform stream
and has shown, that there can be periodic inspissations meteoroids. However
his work represents only theoretical interest. For practical predictions it
is necessary for examining in more details.
