根据３ 种不同观测资料，计算和分析了有关诊断具有耗散结构的系统混沌运动的特征量：功率谱、关联维数、Ｌｙａｐｕｎｏｖ 指数和关联熵。结果表明：尽管下垫面明显不同，大气边界层湍流均为混沌运动。
Based on the three different observation data, the characteristic quantities of chaotic motions of system with dissipative structure are calculated and analyzed: power spectrum, correlation dimension, Lyapunov exponent and correlation entropy. The results show that turbulence in the atmospheric boundary layer is chaotic even though the underlying surfaces are significantly different.
