coefficient ntawm thermal nthuav dav
Cov khoom nthuav thiab kev cog lus vim qhov hloov ntawm qhov kub thiab txias. Nws lub peev xwm hloov tau hais tawm los ntawm qhov hloov ntawm qhov ntev tau los ntawm chav ntsuas kub hloov hauv qhov sib txig sib luag (p tas mus li), uas yog, qhov coefficient ntawm thermal expansion. Cov thermal expansion coefficient ntawm txhua qhov khoom kuj sib txawv, thiab chav tsev ntawm thermal expansion coefficient ntawm cov hlau dav dav yog 1 / degree (Celsius).
