摘要：

It is shown that the equation u(tt)-u(xx) + sin u = 0 with boundary condition u(x, t) -> 0 (mod 2 pi) as vertical bar x vertical bar -> infinity, which describes a classical field with essentially nonlinear interaction, is a completely integrable Hamiltonian system. The results are interpreted in terms of particles corresponding to the field u (x, t).
