红柱石分解过程的分形研究

Study on the Fractal of Andalusite Grains Decomposed

摘要: 在对红柱石的热分解进行实验研究的基础上,运用周长-面积法测定了分解颗粒的分形维数,并利用分形维数与反应时间的关系探讨了红柱石分解反应的历程。结果认为莫来石晶核化是该分解反应的速度控制环节。

Abstract: Based on the experiment of decompostion dynamics of andalusite, the frac-tal dimensions of the decomposed grains have been measured by means of the perime-ter-area mathod. The reaction mechanisium has also been discussed with the relation ofthe fractal dimension and the reation time.
