摘要(Abstract)：

本文研究探讨了大学物理课程与无线电通信相关专业课程之间的衔接问题。首先,梳理了热噪声研究的历史脉络,明确了噪声温度概念的起源,并给出了噪声温度的一般性定义。其次,以天线作为电磁波换能器为切入点,结合黑体辐射理论与基尔霍夫热辐射定律,推导了天线热噪声功率谱密度的定量表达式。在揭示天线热噪声物理机制的基础上,阐述了天线噪声温度概念的构建逻辑与物理内涵。教学实践表明,将上述思路融入教学,加深了学生对相关物理知识的理解。本研究旨在深化学生对大学物理课程中黑体辐射理论的理解,同时为无线电通信专业课程的教学提供参考,通过将基础物理理论延伸至无线电通信领域,体现了基础物理课程在课程体系中的桥梁作用,有助于培养学生的跨学科综合素养与创新性思维能力。

关键词(KeyWords)： 课程衔接;黑体辐射;天线热噪声;噪声温度;功率谱密度
