摘要
本文用新近发展起来的混沌理论,对流化床内壁传热表面温度波动进行了分析研究,发现温度变化具有显著的混沌特性。在快速傅里叶变换为宽带频谱难以分析的情况下,混沌分析可以从吸引子的演变发现其变化规律。
The wall temperature fluctuations in a fluidized bed are studied with the newly developed chaos theory. The results strongly show that they have chaos characteristics. For the time series with broadband Fourier spectrum, the system evolution can be clearly seen from the changing of attractors.
