摘要
牛顿冷却定律指出物体损失热的速率与其周围环境间的温差是成比例的,但牛顿冷却定律有一定缺陷和局限性。 本文对牛顿冷却定律随温差变化的适用性进行了探讨,结果显示牛顿冷却定律随着温差的升高而适用性下降,并且计算了相对误差的大小,同时对牛顿冷却定律进行了不同温度差下的修正,给出牛顿冷却定律的适用范围。
关键词:

Abstract:
Newton’s law of cooling has some limitations.The applicability of Newton cooling law at different temperatures is discussed.The results show that the applicability of Newton’s cooling law decreases with the increase of temperature difference,and the relative error is calculated.The Newton’s cooling law is modified under different temperature differences,and the application range of Newton’s cooling law is given.
Key words:
Newton’s law of cooling
range of application
relative error
