gravitation potential meaning in Chinese

重力势

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
本文重点分析了扰动引力对不同射程导弹的落点偏差的影响，并且讨论了原有计算扰动引力的球谐函数法在计算速度上的缺陷(由于勒让德函数的递推计算，使得随着模型阶数的增加模型的计算速度下降) ，然后对其进行改进使其能更好的适用于弹道计算。
