摘要
利用物理摆原理导出了自动安平水准仪磁致误差的理论函数模型，建立了地磁场中的观测方程。通过实测资料，分析了地磁场对Ｎｉ００２水准仪的影响，并对观测误差和Ｆ值的测定精度进行了讨论。
Based on the theory of horizontal pendulum, the theoretical function model of magnetic error of self adjusting level is deriveted, and observation equation in geomagnetic field is set up. Using measurement datum, the influence of geomagnetic field on level Ni002 is analyzed. The measurement errors and the accuracy of determining F value are discussed.
