(三)谁是测量的对象常常可以听见这样的一些话:“请量量这块布有多长?”或“请称一下这只鸡有多重?”等等。通常都把它理解为:要量的是这块布和要称的是这只鸡。但是,这样的理解是不对的!不错,被测的实体的确是特定的布和鸡,但是我们所要测量的东西(测量的对象)却是体现在被测实体上的某种特征、特性或状态。应该这样来理解:被测的是布的长短和鸡的轻重而不是布和鸡。长短和轻重就是体现在这块布和这只鸡上的特征和特性。在上一章里我们曾经说过,能反映事物(现象和物质)的特征、特性和状态的东西叫做量(即可测的量)。在物质世界里,存在着各式各样的量。例如反映长短这一特征的长度、反映冷热特性的温度、反映光线明暗的亮度、反映轻重的质量、反映快慢的速度、反映酸碱程度的酸度等等就
(C) Who is the object of measurement Can often hear such words: “Please measure the length of this piece of cloth?” Or “Please weigh the number of chicken?” And so on. Usually understood as: the amount of this piece of cloth and to be called this chicken. However, this understanding is wrong! Well, the measured entity is indeed a specific cloth and chicken, but what we want to measure (measured object) is reflected in the measured entity on a certain feature, characteristic or state . It should be understood: the length of the cloth is measured and the weight of the chicken instead of cloth and chicken. Length and severity is reflected in this piece of cloth and chicken on the characteristics and characteristics. We have said in the previous chapter that something that reflects the characteristics, characteristics, and states of things (phenomena and matter) is called quantity (ie measurable quantity). In the physical world there are all kinds of things. For example, reflect the length of the length of this feature, reflecting the hot and cold characteristics of the temperature, reflecting the brightness of light and shade, reflecting the quality of light and heavy, reflecting the speed of the acidity of acid and so on
