江西省永新县芦溪中学左青同学问：“对绝对零度怎么理解?”在回答这个问题前,我们首先要了解温度的概念,初中物理教材告诉我们．物体的冷热程度用温度表示。但是,人们对冷热的主观感觉往往是既不可靠又不准确的,所以,上述对于温度的通俗理解是不够的,需要有严格的定义和准确的数值表示方法。 The student of Zuo Qing of Luxi Middle School in Yongxin County, Jiangxi Province asked: “How do you understand the absolute zero?” Before answering this question, we must first understand the concept of temperature, and junior middle school physics textbooks tell us. The degree of coldness and heat of the object is expressed in terms of temperature. However, people’s subjective feelings of cold and heat are often unreliable and inaccurate. Therefore, the above general understanding of temperature is not enough, and it requires strict definition and accurate numerical representation.
