Numerical simulations of one-dimensional Langmuir turbulence carried out by the authors are reviewed. The pumping of the plasma wave energy to shorter wavelengths is shown to result when supersonic solitons collapse. Including Landau damping in the short-wave part of the plasma-wave spectrum gives rise to quasisteady turbulence. The basic integral characteristics of this turbulence: the energy of the plasma waves, the energy of the acoustic waves, and the effective collision frequency: are determined. The intensification of short acoustic waves and the effect of this intensification on the dynamics of the Langmuir turbulence are studied. The formation of tails on the electron distribution function is considered. The turbulence initiated by an electromagnetic wave at frequencies very different from the plasma wave is studied.
