利用球调和模型、中国地壳运动观测网基准站和IGS基准站的GPS观测数据，分别计算中国和全球区域的总电子含量，并采用不同的统计分析方法，对汶川震中及周边地区的TEC进行了检验。赤道。
Utilizing spherical harmonic model,the GPS observational data of fiducial station in the crustal movement observation network of China and IGS fiducial station,calculating the total electron content of Chinese and global region respectively,and adopting different statistical analysis method,we examined the TEC on Wenchuan epicenter and around the region.As a result,we found that the anomalous VTEC disturbances over seismic preparation zone continuously took place in a week before and after the earthquake,whose form had conjugate structure and shifted to magnetic equatora.
