摘要 2002年对兰州观象台FSQ与SSY-Ⅱ两套仪器同时进行模拟与数字记录发现,模拟记录与数字记录有着较为明显的差异。为了对比模拟记录与数字记录的优劣,对FSQ的两套观测资料进行了年趋势变化、调和分析、日均值的相对噪声水平等的对比分析,对SSY-Ⅱ的资料进行了年趋势变化、调和分析、Nakai检验等的对比分析。通过对比发现模拟记录与数字记录的差异,是由于对这两种资料的处理不一致造成的。 Both of FSQ and SSY-II instruments were set to record the digital and analog data simultaneously in Lanzhou Observatory in 2002.The apparent difference between two kinds of data was found.To make out the reasons,the comparison was done,which included the analysis of data by FSQ on the year's tendency variation,the regularity and the relative noise level and of data by SSY-II on the year's tendency variation,the regularity and Nakai test.The comparison reveals that for the same instrument,its digital and analog data kept well in line,but different data processing methods would result in deviations in the two kinds of data.
