Research And Application Of Regional Geomagnetic Survey

The geomagnetic field research is a national basic task. The research to the partial geomagnetic field is not only one part of the geomagnetic field research, but also one part of digital earth. The primitive data of the research to the partial geomagnetic field and the method to its data is national precious resources, it also is needed for the other aspect such as the constructions of national economy Geoscience transportation the probe into resources aviation seismic forecast monitor to environment and weather etc. So the research to the partial geomagnetic field is of scientific and practical importanceIn this paper, we firstly introduce the basic theories of the geomagnetic field and the information of the survey to the related magnetism. Then the mode to the partial geomagnetic field is been drawn emphasize. The method of laylor is been adopted during the studying mode to the partial geomagnetic field. Based on the mode we have done system's analysis and a flood of experiment. Thirdly we discuss the partial mode after statistics and analyze, we deduced digital mode of the geomagnetic angle on the fiducial position We adopted the choice to the intending of period match in order to suit the period of the geomagnetic field.Finally, we adopted the different method such as single and double to correct the primitive fiducial data. And a new idea to treat the abnormality of the geomagnetic field is presented.geomagnetic field; geomagnetic angle-, partial mode; fiducial position; choice to the intending of period match; different; geomagnetic abnormality ; diurnal correction.
