(Ⅰ )报已对磷矿颗粒的扩散和反应过程进行了理论探讨 ,在系统研究金河磷矿、晓峰磷矿、开阳磷矿这3种有代表性的磷矿晶体微结构参数、物相组成等物理化学特征的基础上 ,实验研究了这些磷矿中包括杂质在内的反应动力学过程 ,并发现了铁铝杂质在反应中的负温度效应 .采用 (Ⅰ )报得到的动力学方程描述这些过程 ,获得了较满意的结果 ,分形扩散中的特殊现象和扩散中所产生的自相似结构均在实验中获得了证实
(Ⅰ) reported that the diffusion and reaction process of phosphate rock particles have been discussed theoretically. Three representative phosphate rock crystal microstructure parameters of Jinhe Phosphate Mine, Xiaofeng Phosphorite Mine and Kaiyang Phosphorus Mine were systematically studied. Phase composition and other physical and chemical characteristics, based on the experimental study of these phosphate rock including impurities in the reaction kinetics and found that the iron-aluminum impurities in the reaction of the negative temperature effect.Using (I) reported that the power Learning equations describe these processes and obtain satisfactory results. The special phenomena in fractal diffusion and the self-similar structures in diffusion have all been confirmed experimentally
