主成分回归法研究热分析中样品用量与表观活化能实测值之间的关系

Principal component regression method of studying the relation between sample mass and experimental value of apparent activation energy

以硫酸镍热分解过程为例 ,使用主成分回归法拟合了样品用量与表观活化能实测值之间的关系式 ,并讨论了主成分回归法在这一类问题中应用的特点。

This paper studies the effect of sample mass on actual determination result of apparent activation energy in nickel sulphate thermal decomposition process,formulating the relation between sample mass and experimental value of apparent activation energy by using the the principal component regression method.It also discusses advantages of the method in dealing with this category of problems.
