| 摘 要： | 选择上海地区具有代表性的两种土壤样品,根据其微结构的特点,在粒径分布、剖面颗粒分布自相似规律的基础上建立了土壤结构分形模型;结合并联传热,得到土壤样品有效导热系数的分形表达式.通过与土壤样品有效导热系数的实测数据相比较,确立了符合样品有效导热系数的分形表述的最佳面积度量尺度. |

| Abstract: | The fractal theory used in this paper is based on microstructure characteristics of two types of typical soil in Shanghai.Their microstructures are described on the ground of particle-size distribution and particle distribution on the vertical plane.The formulae of efficient thermal con-ductivity are given out by the method of equivalent thermal resistance.By comparison with experi-mental measurement,the optimal area measurement scale has been established. |
| Keywords: | soil sample efficient thermal conductivity fractal model |
