CURVATURE RELATION OF WAVE FRONT AND WAVE
CHANGING IN EXTERNAL FIELD
刘深泉,宋乐
The changing of wave structure in excitable
media in external field is studied and the curvature relation of wave front is
analyzed. Under external stimulus the normal velocity of wave front has linear
relation with mean curvature of wave front, plane velocity and external field.
The simulation methods have been used to analyze Bar-Eiswirth model with
external field and obtain the wave pattern of excitable media contained
external stimulus. These theoretical analysis and simulation results are
identical with experiments of BZ reaction. So the results here theoretically
explain the BZ phenomenon under external field and the simulation results here
have rich wave patterns.
