摘要
国际地磁参考场是正常地磁场的一种表达模式,简称IGRF,它可用于地球物理勘探、航海、国防等领域。本文列出了1990-1995的球谐系数并详细叙述了计算的公式、步骤与技术。
Abstract
International geomagnetic reference field is a show's model of normal geomagntic field, for short IGRF. The field is used in field of whsical exploration navigation and state dsfense.Spherical harmonic coefficients (1900~1995) are given and formulas, steps and techniques of computahon are detailed in this paper.
