In this paper, we not only analysed the different effects of the disturbing gravitation on the trajectories of different ranges, but also discussed shortcomeings of the spherical harmonics model by which the external gravitation potential of the earth is shown usually. when the model is applied directly to the calculation of the trajectory, since the recurrent calculation can not be avoided, an increase in orders of model will result on a decrease in the speed of calculation
本文重點分析了擾動引力對不同射程導彈的落點偏差的影響，並且討論了原有計算擾動引力的球諧函數法在計算速度上的缺陷（由於勒讓德函數的遞推計算，使得隨著模型階數的增加模型的計算速度下降） ，然後對其進行改進使其能更好的適用於彈道計算。With the recurrent calculation got rid of, the speed of calculation is increased. practical calculations have shown that the new model not only have the high precision but also enables us to enhance the speed of calculation 6 or 7 times. so it is testified that the new model is superior to the spherical harmonics model
通過將換極后的球諧函數用於彈道計算，得出換極后的球諧函數不僅在計算精度上可達較高要求，而且計算速度也明顯優于未換極的球諧函數（新模型的計算速度是約為換極前模型的6 7倍） 。Derivative calculation and application in spherical cap harmonic analysis of local gravity field
