Abstract:
Characteristic on the tangent of dielectric loss angle for coal has been researched by using fractal geometry theory.The results show that the tangent of dielectric loss angle of coal has fractal characteristic,relationship between and frequency is:tg**f(D-d)/2,and fractal dimension of tg* for coal could be obtained.

煤介质损失角正切的分形特征
徐龙君,顾乐观,鲜学福
摘要:
利用分形几何理论对煤的介质损失角正切的特征作了深入的探讨·结果表明,煤的介质损失角正切tgδ具有分形特征;通过类比和实验证实的方法得到了tgδ与f间的定量关系:tgδf(D-d)/2,借此求得了煤分形介质损失角正切维数。
