摘要
本文介绍第54届国际物理奥林匹克竞赛理论考试的第一题.该题以温室效应全球变暖为背景,考查黑体辐射和热传导中的能量平衡.题目分成两部分,第一部分关注黑体辐射的辐射能分布;第二部分关注反射吸收下,能量的平衡.题目涉及近代物理(黑体辐射);热学中的能量传输,以及类似光学中多光束干涉时的法布里-珀罗效应.
Abstract
This paper introduces the first question of the theoretical examination of the 54th International Physics Olympiad.The question is set against the background of global warming due to the greenhouse effect,and it examines the energy balance in blackbody radiation and heat conduction.The question is divided into two parts:the first part focuses on the distribu-tion of radiant energy in blackbody radiation;the second part addresses the balance of energy under reflection and absorption.The question involves modern physics(blackbody radiation),energy transfer in thermodynamics,and the Fabry-Perot effect similar to that seen in multi-beam interference in optics.
