摘要
本文用积分法模拟恢复了地球重力场，同真实重力场进行比较，分析了结果。结果表明，本文使用模型及程序算法正确，可以用于恢复重力场，精度在10^-12的量级上，对应的大地水准面阶误差小于0．2mm，大地水准面累积误差30阶处小于0．5mm。
In this paper, comparing with the real earth gravity,the earth gravity is simulated and recovered by integral method. Some conclusions are drawn out by analying results. The results indicate that the model and software are correct and are adequate for earth gravity recovery.The RMS （root mean square） of gravity model coefficient is 10^-12, the corresponding geoid height error is 0.2mm and the accumulated geoid height error is less than 0.5mm within 30 degree.
