我们平时都用酒精温度计测量体温、气温,它是接触式测量。可是,对于温度超过了它的沸点78℃,或者低于它的凝固点-114℃的高温物体、极冷物体;又或者被测物体离得太远或者无法接触到,或者对温度精确度要求很高的情况下,该怎样测量温度呢?那些在极冷、极热、极远迥然不同的环境中,是无法直接测量温度的。不过,科学家们可以运用物理定律和已知的知识来推断那些未知的世界,从而达到测量温度的目标。 We usually use the alcohol thermometer to measure body temperature, temperature, it is a contact measurement. However, for objects whose temperature exceeds its boiling point of 78 ° C, or is below its freezing point of -114 ° C, very cold objects, or the measured object is too far away or inaccessible, or the temperature accuracy is very high In the case of high temperatures, how to measure the temperature? Those extremely cold, very hot, extremely different environment, it is impossible to directly measure the temperature. However, scientists can use physical laws and known knowledge to infer those unknown worlds in order to reach the goal of measuring temperature.
