αμ

en
temperature coefficient of permeability
the fractional change of permeability due to a change in temperature divided by that change in temperature:

α μ = μ θ μ ref μ ref ( θ θ ref ) MathType@MTEF@5@5@+=feaagCart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHXgaruavP1wzZbItLDhis9wBH5garmWu51MyVXgarqqtubsr4rNCHbGeaGqipG0dh9qqWrVepG0dbbL8F4rqqrVepeea0xe9LqFf0xc9q8qqaqFn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpeWZqaaeaaciWacmGadaGadeaabaGaaqaaaOqaaiabeg7aHnaaBaaaleaacqaH8oqBaeqaaOGaeyypa0ZaaSaaaeaacqaH8oqBdaWgaaWcbaGaeqiUdehabeaakiabgkHiTiabeY7aTnaaBaaaleaacaqGYbGaaeyzaiaabAgaaeqaaaGcbaGaeqiVd02aaSbaaSqaaiaabkhacaqGLbGaaeOzaaqabaGcdaqadaqaaiabeI7aXjabgkHiTiabeI7aXnaaBaaaleaacaqGYbGaaeyzaiaabAgaaeqaaaGccaGLOaGaayzkaaaaaaaa@50C0@
