前言尽管有人用差示扫描量热法(DSC)对碳酸氢铵的热效应做过研究。但是迄今还未见到有关用DSC对碳酸氢铵热分解动力学进行研究的报导。我们的这一工作正好填补这一间隙。碳酸氢铵是一种较好的氮肥品种,它具有易被土壤吸附、肥效高、能促进作物早发 Introduction Although the thermal effect of ammonium bicarbonate has been studied by differential scanning calorimetry (DSC), However, no report on the kinetics of thermal decomposition of ammonium bicarbonate has been reported so far. Our job just fills this gap. Ammonium bicarbonate is a good nitrogen fertilizer species, it has easy to be soil adsorption, high efficiency, can promote early crop
