| 英文摘要 | Based on the geomagnetic survey data in the eastern and central region of China for 1936, and DGRF1935 and DGRF1940, using the method of spherical cap harmonic analysis, the spherical cap harmonic model of the Chinese geomagnetic reference field for 1936(CGRF1936) is calculated. The truncation order of the spherical cap harmonic model is 8, the pole of the spherical cap is at 36degreesN and 104degreesE, and its half-angle is 30degrees. CGRF1936 can express the distribution of the geomagnetic field in China better than the corresponding DGRF. The root mean square (RMS) deviations of SCH model are 104.9 nT for X, 84.8 nT for Y, and 121.1 nT for Z, respectively. Based on the SCH model of the geomagnetic field, the geomagnetic charts( X, Y, Z, F) and anomaly charts (DeltaX, DeltaY, DeltaZ, DeltaF) in China for 1936 are drawn. |
