Query: Mean Switching Frequency Locking in Stochastic Bistable Systems Driven
  by Periodical Force   The nonlinear response of noisy bistable systems driven by strong amplitude
periodical force is investigated by physical experiment. The new phenomenon of
locking of the mean switching frequency between states of bistable system is
found. It is shown that there is an interval of noise intensities in which the
mean switching frequency remains constant and coincides with the frequency of
external periodic force. The region on the parameter plane ``noise intensity -
amplitude of periodic excitation'' which corresponds to this phenomenon is
similar to the synchronization (phase-locking) region (Arnold's tongue) in
classical oscillatory systems.
