Linear expansion coefficient
Qee zaum hu ua linear expansivity (linear expansivity), qhia qhov ntsuas qhov txav ntawm cov khoom txav lossis nqes tau. Muab faib rau hauv qhov ntsuas kub ntawm linear expansion coefficient thiab qee qhov kub thiab txias ntawm qhov linear expansion coefficient, tom kawg hu ua qhov nruab nrab linear expansion coefficient. Cov qub yog elongation ntawm ib chav ntev ntawm cov khoom hauv ib qib ntawm nce; qhov nruab nrab linear expansion coefficient yog qhov nruab nrab elongation ntawm ib qhov ntev ntawm cov khoom hauv qee qhov ntsuas kub, ib puag ncig ntawm kev ntsuas kub nce ntxiv.
