| 摘 要： | 根据国际参考地磁场(IGRF)模型,计算出1945年5月—1990年5月中国部分地磁台的计算年均值,并与相应观测年均值比较,计算出地磁台各个地磁要素的磁异常值以及地磁台异常场的模量,本文的计算结果将为认识地磁台的地磁场环境、地磁台站资料评比提供依据。

| Abstract: | Based on the international geomagnetic reference field(IGRF)model,1945.5- 1990.5 annual mean values of Chinese geomagnetic observatories were calculated. The difference values between the observed annual mean values and calculated annual mean values were called the geomagnetic anomaly values of the geomag- netic elements on geomagnetic observatories.The modulus of the anomaly field on observatories were calculated too.According to these calculation results,the geomagnetic environmental field on the geomagnetic observatories were analysed. |
