摘　　要：根据溶液中存在结构起伏和能量起伏,建立"笼子"效应模型,研究碳酸钠与多钒酸铵反应体系中的动力学机理。理论上导出了碳酸钠与多钒酸铵反应时反应温度T与反应时间t的关系,并通过大量试验数据回归得到T、t的关系。实验数据与模型导出关系吻合,表明碳酸钠与多钒酸铵反应符合该反应模型和动力学机理。A ＂cage＂ effect model was established based on solution in which existed structure and energy upsand downs. The relationship between reaction temperature T and reaction time t was studied when Na2 CO3 and multi-vanadium-acid-ammonium was reacting. The relationship between T and t has been verified by a large number of testsand accorded with the derived model. The results indicated that the reaction corresponded to the reaction model anddynamic mechanism.
