Gruzleski in his book Microstructure Development During Metalcasting (1996): α = (L/k *TE) *(η/v) where L is latent heat of fusion k is Boltzmann’s constant TE is equilibrium freezing temperature η is the number of nearest neighbours an atom has in the interface plane v is the number of nearest neighbours in the bulk solid Since L/TE = ΔSf where ΔSf is the molar entropy of fusion of the material α = ΔSf/k(η/v) According to Martin Glicksman in his book Principles of Solidification : An Introduction to Modern Casting and Crystal Growth Concepts(2011): α = ΔSf/Rg(η1/Z) where Rg is the universal gas constant, (η1/Z) is similar to previous, always 1/4<(η1/Z)<1 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Alpha factor」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
