| 摘 要： | 选用德都台2011—2012年的地磁基线值数据,来分析绝对观测数据、相对记录数据和温度数据对基线值的影响。通常基线值的主要影响因素除温度外,还与人为观测误差、湿度和记录墩的稳定性有关。首先保证绝对观测固定为同一人员,确保人为观测误差忽略不计,再排除湿度与记录墩的不稳定性,最后利用回归分析计算方法,得到基线值数据与温度数据的回归方程,并对该方程进行显著性检验,表明地磁基线值与温度之间存在良好的线性关系,再以此回归方程来判断我台地磁数据的好坏,为更好的改进我台地磁观测数据质量提供依据。

| Abstract: | In this paper,the geomagnetic baseline data of dedu Seismic Station from 2011 to 2012 were selected to analyze the impact of absolute observation data,relative recording data and temperature data on the baseline value.In general,the main influencing factors of baseline values are not only temperature,but also human observation error,humidity and stability of record piers.First guarantee absolute fixed for the same personnel,ensure that artificial observation error is negligible,eliminate the instability of humidity and record the pier again finally by using regression analysis method,regression analysis was carried out on the baseline value and temperature,get in statistical sense,baseline and the regression equation of the temperature and significance test of the equation,show that geomagnetic baseline value exists a good linear relationship with temperature,then to regression equation to judge of my station geomagnetic data,to better improve my quality of geomagnetic observation data. |
