  • 摘要: 任何一个物理量都是用来量度物质系统的某种性质的。惯性是用质量来量度的。本文讨论了质量是否是量度惯性的物理量这一问题。为此,我们首先讨论了惯性这一概念,引入了量度惯性的方法。只要我们所讨论的物体的质心速度比极限速度c小很多,相对论质量可以用来量度其惯性。然而,在一般情况下,它没有这个功能。如果物体的质心速度是相对论速度,则质量(无论是静质量还是相对论质量)就失去了量度惯性的功能。然而,物体的惯性可以用其特征曲线来描述。
  • Any physical quantity is a measure of a property of a physical system.We are concerned with the property inertia. It is known to be measured by thephysical quantity mass. We were concerned with the question of whether massis a measure of the property inertia. For this purpose, we first settled what wewant to understand by inertia, and we introduced a measure for it. As long asone considers movements with center-of-mass velocities much smaller thanthe terminal speed c, relativistic mass measures inertia. In general, however, itdoes not. If we allow for relativistic center-of-mass velocities, the mass loses thisproperty. Neither the rest mass nor the relativistic mass is a measure of inertia.However, the inertial behavior can now be described by a characteristic curve.
