摘要：
A series of experimental studies on spiral dynamics and instabilities in a spatial open. reactor with the Belousov-zhabotinsky (BZ) reaction are reported. We present a phase diagram showing different spiral dynamic regimes. Two types of spiral instabilities, the Doppler instability and the long wavelength instability, are observed in the experiments. All these instabilities lead to a state of spatiotemporal chaos or chemical turbulence. Theoretical explanation are given for each, instability.
