| 英文摘要 | Based on geomagnetic data of 426 geomagnetic sites and calculated from IGRF at 28 sites for 1936.0, surface Spline models for various components of the geomagnetic field and geomagnetic anomaly field are calculated, and the corresponding geomagnetic field charts and geomagnetic anomaly charts are drawn. According to the secular variation charts of geomagnetic declination D during 1909 similar to 1915, 1915 similar to 1920, 1920 1930 and 1930 similar to 1936, the secular variation charts of horizontal intensity during 1908 similar to 1917, 1917 similar to 1922 and 1922 similar to 1936, as well as the secular variation charts of vertical intensity during 1908 similar to 1922 and 1922 similar to 1936 in partial regions of China, the surface Spline models of secular variations are respectively calculated for the geomagnetic declination (D), the horizontal intensity (H) and the vertical intensity (Z) during the above-mentioned 9 periods by using the surface Spline method, and the corresponding secular variation charts are drawn. According to these secular variation models, the absolute value data of three components at 426 sites for 1936.0 are reduced to 1940, 1930, 1920, 1910 and 1900. These data have laid a solid foundation for calculating the geomagnetic field models for these 5 epoches. |
