Will curve fittingdata synthesis, for further discussions and concluded.
将数据拟合成曲线，作进一步讨论并得出结论。
2
The relative error between the fittingdata and the measured data is less than 5 %.
拟合结果与实测值的相对误差小于5％。
3
Through using actual GPS leveling fittingdata in a large-scale area, it introduces the application of optimum function model choice and the related analysis method.
