摘　　要：通过表观重力场的定义,严格导出了在考虑地球自转情况下的重力场非均匀修正公式,然后在地面参考系列出了考虑地球自转情况下的落体运动微分方程,最后用逐级近似法导出了新的落体南偏公式,其结果与采用地心参考系的方法所得结果是一致的.By representing the definition of the gravitational field, the uneven modified equation of the gravitational field was deducted strictly by consideration of the earth rotation. The differential equation of the free fall movement under the condition of earth rotation was also given in the frame of ground reference. Finally, the new free fall south-deviation formula was deducted by the gradual approximation method, which was consistent with results by using the frame of earth＇s core reference.
