一、前言自然界中多姿多彩、纷繁变幻的光学现象激励人们不断认知和探索丰富的未知世界。在地球大气层之外,存在一个叫做“空间环境”的领域,它涵盖从离地面大约20km开始一直延伸到太阳的广阔空间。空间物理学研究这一区域内千变万化的物理现象,探寻其中未知的物理规律,其研究结果将为人类的通信和航天活动提供基础数据和物理模型。空间环境中从离地面大约20km开始到300km高度的中高层大气区域内,就存在着多种多样的光学现象,引导人们去研究这 I. Preface The colorful and colorful optical phenomena in nature inspire people to constantly recognize and explore the rich and unknown world. Outside the Earth’s atmosphere, there is an area called “space environment” that covers a vast space that extends from the ground about 20km to the sun. Space physics studies the ever-changing physical phenomena in this area and explores the unknown laws of physics. The findings of this study will provide basic data and physical models for human communication and space activities. In the space environment, there are many kinds of optical phenomena in the middle and upper atmosphere area from about 20km to 300km above the ground, leading people to study this
