查询词典 propagation medium

This thesis is to study the wave pattern selection in the heterogeneous reaction-diffusion systems, including propagation direction of target waves induced by a localized inhomogeneity, large heterogeneity maintained sinklike spiral waves in oscillatory media, and the competition of coherent wave patterns sustained by a localized inhomogeneity with turbulent waves in an excitable medium.
