摘要： 以特定杆件长度方向上的热变形变化量来定义的材料线膨胀系数,实际上是杆件长度方向上的热变形系数,因此存在原理误差.该文对此进行了详细的论述,并提出了材料热膨胀系数的科学定义.

关键词: 线膨胀系数, 热变形系数

Abstract: The linear thermal expansion coefficient of material defined as the change in length suffered by a unit length of the special rod when its temperature is changed by 1℃ is really the thermal deformation coefficient of its length, so there exists an error of theory in the coefficient. This paper details these problems and puts forward a new scientific definition of the linear thermal expansion coefficient.

Key words: linear thermal expansion coefficient, thermal deformation coefficient
