基于豪斯多夫维数的烟叶质量分形特征研究——以贵州、云南烤烟烟叶含梗率为例

Fractal Theory and Application in Tobacco Quality Management——Taking Data from Guizhou and Yunnan Province for Example

烟草质量的变化是烟草质量管理的重点,长期以来研究人员都在探索烟草质量变化的理论模型。本文将烟叶含梗率的变化理解为非周期性循环,运用基于Hurst指数的R/S分形理论对贵州省和云南省烟叶含梗率的变化序列进行分析检测,估算出平均循环周期和分形维,评估两省烟叶含梗率的稳定性和含梗率形成系统的复杂性。

The change of tobacco quality is the key point of tobacco quality management so researchers have studied and discussed the theories and models to interpret this change. The stem ratio sequences in Guizhou and Yunnan Provincewere discussed in non-periodic cycles. S fractal theory bases on hurst indicator to evaluate the The cycle length and fractal cone were calculated via R/ stability and complexity in stem ratio system.
