摘　　要：基于空域截断理论,研究推导了空域截断逼近模式下的Stokes公式远区截断误差表达式。利用EGM2008重力场模型,量化分析了远区截断误差、移去参考场阶数以及积分半径三者间的关系,为积分半径和移去阶数的最优选取提供了参考。Base on the method of space domain truncated approximation, the expression of the Far-zone effect in Stokes Formula is derived.The simulation experiments that base on the EGM2008 gravity model is designed, and the relationship between truncation error, reference field order and integral radius of Stokes formula is quantitatively analyzed, which provided an optimal selection basis for reference field order and integral radius.
