温度温度是指从特定标尺上测量出来的、表示物体冷热程度的一个物理量。一切物体均由大量分子组成,分子总是处于运动状态。分子运动愈快,物体愈热,反之则愈冷。这种现象被描述为一个物体的热势或能量效应。当用数值加以表示时,即称之为温度度数。为了测量温度,必须确定温度基准值和温标。 Temperature Temperature is a physical quantity measured from a particular scale that indicates the degree of hot or cold of an object. All objects are composed of a large number of molecules, the molecules are always in motion. The faster the molecule moves, the hotter the object, and vice versa, the colder. This phenomenon is described as an object’s thermal or energy effects. When expressed in numerical terms, that is called the temperature degree. In order to measure the temperature, the temperature reference and the temperature scale must be determined.
