本文测定了线性加热速率下的Ni50A120Fe30（wt％）体系热爆反应过程的DTA曲线．用差商法计算了该SHS热爆过程的活化能和反应级数，其结果与用燃烧被违法得到的数值基本一致．

The DTA curve of Ni50A120Fe30 (wt%) thermal explosion synthesis under linear heating rate was measured. The activation energy and reaction order of the SHS thermal explosion were calculated by using the Difference Quotient Method. The obtained results were essentially the saxne as that from the method of Combustion Wave Velocity.
