| 摘 要： | 频率是自然界中测量得最准的物理量.量子频标是频率的测量标准,它是利用原子跃迁谱线的稳定而准确的频率作为参考频率.频标研究中存在几乎所有的原子物理问题,如原子结构与光谱、原子与电磁场的相互作用以及原子碰撞等问题值得深入研究.本文就量子频标的基本原理和应用,量子频标中存在的原子物理问题做以简要评述.

| Abstract: | Frequency is the most accuracy measurement quantity in the nature.Frequency Standards is the standard of frequency measurement,it based on atomic transfer spectra lines which is high accuracy and stability.In the study of frequency standards there are almost problems of atomic physics,such as atomic structure and spectroscopy,interaction between atom and electronic and magnetic fields,and atom collision processes.In this paper the basic principle and application of frequency standards was given,and the atomic physical problem relative to frequency standards was briefly reviewed. |
