摘要：

A　novel　model　for　activation　energy　calculation　derived　from　the　Arrhenius　Equation　is　presented　in　this　paper.　Firstly,　value　assignment　method　is　adopted　to　prove　that　the　calculation　error　of　model　1　is　13%,　and　the　calculation　error　of　model　2　is　1.57%　while　the　calculation　error　is　only　0.29%　by　using　the　novel　model.　The　result　testifies　the　higher　precision　of　the　new　model.　Secondly,　the　stability　of　the　new　model　is　verified　by　comparing　the　results　of　the　three　models　mentioned　above　in　the　case　of　data　fluctuation.　The　calculation　error　of　model　1　is　9.14%　and　the　error　of　extrapolated　lifetime　is　91.08%.　For　model　2,　the　calculation　error　reaches　23.7%　and　the　error　of　extrapolated　lifetime　is　80.86%.　The　calculation　error　is　only　3%　and　the　error　of　extrapolated　lifetime　is　25.3%　by　using　the　new　model.　Finally,　to　demonstrate　the　advantages　of　the　novel　model,　experimental　data　is　processed　by　using　the　three　models,　which　shows　that　the　lifetime　acquired　from　the　activation　energy　calculated　with　the　novel　model　is　more　reasonable.　©　2011　IEEE.
