中文摘要：
详细介绍了短程飞行时间吸收谱测量冷原子温度的基本模型和实验方法.在对铯原子磁光阱中冷原子温度测量的基础上,分析了初始时刻冷原子云中心到探测光束中心的垂直距离、冷原子云初始半径、探测光束半径三个参数的误差分别对于通过短程飞行时间吸收谱测量冷原子温度时所带来的影响,并比较了这些参数各自的影响程度.
英文摘要：
The basic model and the experimental measurement method of short-distance time-of-flight absorption spectra for determining the temperature of cold atoms are described. Based on the realization of temperature measurement of cold cesium atoms in a magneto-optical trap, the influences of measurement errors of the three experimental parameters, namely the falling distance h, the initial Gaussian radius σ0 of the cold cloud, and the Gaussian radius σp of probe beam, on the determination of temperature have been analyzed and compared.
