【摘要】 原子氧是低地球轨道中作用于空间飞行器的主要因素。随着空间应用的发展，对原子氧的研究也逐渐成为空间研究的重要内容，原子氧密度的测量则是原子氧研究工作的前提。介绍了几种常用的原子氧密度测量技术，并对各种技术的特点进行了比较。将传统测量技术和新材料的优点结合起来，提出了改进的原子氧密度测量技术，并进行了较深入的研究。更多还原

【Abstract】 The atomic oxygen in the lower thermosphere plays various crucial roles, because it is a dominant and highly reactive constituent in this region.The measurement techniques of atomic oxygen concentration were summarized. The comparison among these methods and current development in this field was also reviewed. An improved quartz-crystal microbalance method for measurement of atomic oxygen was put forward and studied.更多还原
