研究了斯太尔汽车发动机气缸在不同状态下的关联维数，给出了获得反映其真实状态的关联维数方法。研究结果表明：该发动机气缸振动的时间序列在不同状态下关联维数不同，可以将其关联维数作为识别其状态的特征量，给出了利用分形理论判断斯太尔汽车发动机气缸状态的判椐。
The correlation dimension of the cylinder of Steyr engine in different states is studied, and the method of obtaining the correlation dimension reflecting its true state is given. The results show that the correlation dimension of the time series of cylinder vibration in different states is different, and its correlation dimension can be used as the feature quantity to identify the state of the cylinder. The fractal theory is used to judge the state of the cylinder of the Steyr engine椐.
