传热学课程中黑体辐射五大定律关系阐述分析

Describing and Analysis of the Relationship among Five Laws of Blackbody Radiation in the Course of “Heat Transfer”

摘要: 热辐射是“传热学”中最基本、最复杂的一种传热方式。笔者以“传热学”中与热辐射相关的黑体辐射五大定律为例介绍实际教学中的探索和实践，从图像和公式推导两方面详细阐述分析它们之间的关系，从而加深学生对辐射换热的理解，并试图引起他们的学习兴趣和科研乐趣。

Abstract: Thermal radiation is one of the most basic and complex heat transfer modes in “Heat Transfer”. This paper will demonstrate the exploration and practice in the teaching practice using the five radiative laws of the blackbody radiation as an example. From two aspects of graphic demonstration and math formulation derivation, the relationship of the five laws will be described and analyzed in order to deepen students' understanding of the radiative heat transfer, and try to arouse their interest in learning and research.
