摘要：

Analysis of aperiodic oscillations in the chlorite oxidation of thiourea in a continuous-flow stirred tank reactor in terms of time series, reconstructed attractors, Fourier spectra, Poincare sections, return maps, and generalized Renyi dimensions confirms the existence of deterministic chemical chaos in this system. The coincidence of an experimentally observed hysteresis and a discontinuous transition from a stationary state to aperiodic behavior signifies this as homoclinic chaos, which arises from the interaction of a local subcritical Hopf bifurcation and a global homoclinic bifurcation. Homoclinic chaos is characterized by a spiral-type strange attractor.
