title: [Instability and propagation of waves of excitation in a model of a catalytic reaction. III. Non-trivial regimes of propagation of excitation].
abstract: The regime of excitation propagation in a uniform model of an active medium is studied within the parameters where the initial concentrated system is a trigger one. In a distributed system propagation trigger waves as well as impulses can propagate. A means for initiating such impulses is suggested, an unstationary regime of their imitation is investigated by calculations. Piece-linear solutions obtained analytically are shown to be a good approximation for stationary regimes.
