| 摘 要： | 本文根据物理化学基本原理，提出HF的表面吸附催化机制对于CaF2-HCl-H2O固－液反应体系溶解振荡起着关键性作用。同时建立了该 体系的动力学模型，研究其振荡现象的非线性动力学起因，虽然这一数学模型是基于CSTR反应器为对象而建立的，不过其基本的结论对叠层式流动反应器的情况也是适用的。 |

| Abstract: | This study is based on the physical chemistry elementary principle to propose that the surface adsorptioncatalytic mechanism of HF is the key to dissolving oscillation of CaF2-HCl-H2O solid-liquid reaction system. Meanwhile a dynamical model of this system is proposed in order to study its non-linear dynamical genesis. Although this mathematical model is based on CSTR reaction apparatus, it is applicable to the foliate flow reaction apparatus also. |
