  A new approach to analysis of the synchronization of chaotic oscillations in
two (or more) coupled oscillators is described that makes it possible to reveal
changes in the structure of attractors and detect the appearance of
intermittency. The proposed method is based on a symbolic analysis developed
previously in the velocity-curvature space of multidimensional sequences and
maps. The method is tested by application to a Lorentz system. The results
confirm the informativity of the analyzer and reveal specific features of
changes in the structure of an attractor of the three-component test system.
