- 中文摘要: 靈敏度解析所探討的是一個動力系統中動力參數對系統的影響。靈敏度資料與動力參數值之估算,實驗之規劃,以及模式之評估等均有密切之關聯。化學動力學還可藉靈敏度解析以簡化複雜之化學反應機構。 本文旨在簡介當前各種靈敏度計算法,靈敏度資料所包含之動力訊息,並以三個化學動力系統(Chapman臭氧動力機構,Oregonator,與Hidaka-Gardiner-Eubank之甲院氧化機構)為例,詳細討論靈敏度資料之使用法。本文大部份之材料均未曾見諸刊物。
- 英文摘要: Sensitivity analysis is a study which probes the response of a dynamic system to parameter varia-tions. The sensitivity information can contribute directly to parameter estimation, experimental planning,and the assessment of a modelling result. In chemical kinetics, the sensitivity information can also be usedto simplify a mechanistic model by determining kinetically important and unimportant elementary steps.For design studies, information about the sensitivity of a reactor model to initial reactant concentrations,temperature, and so on, can be useful in optimizing certain species profiles. The present review summarizes the various computation methods of sensitivity analysis, presents thebasic usage of sensitivity information, and discusses in detail three illustrative kinetic examples (the Chap-man ozone kinetics, the Oregonator, and the Hidaka-Gardiner-Eubank mechanism for the methane oxida-tion kinetics). The sensitivity calculations for these three systems were carried out in our laboratory andfor the most part have not been previously published.
