摘要：

The exact solution of the Peierls-Frohlich problem on a self-consistent state of conduction electrons and a chain deformation near zero temperature is obtained in the continuum approximation. The charge-density wave (CDW) state in various relations between parameters of the problem (electron density, electron-phonon coupling, CDW velocity) is investigated. The CDW total energy and momentum are calculated and an expression for the effective mass is obtained. Current oscillations are interpreted on the basis of this exact solution.
