| 摘 要： | 本文分析了磨光函数及B样条函数的性质,提出根据已有观测数据,采用磨光函数对测量误差分布曲线进行拟合,推导了三次磨光样条函数拟合误差分布的计算公式,并由实测数据验证了其合理性,研究表明磨光函数具有良好的保凸性和光滑性,可在拟合误差分布及其它各种曲线拟合问题中进行广泛应用。

| Abstract: | The paper analyzed the characteristics of smoothing and B spline function,it is put forward the error distribution fitted according to the existent survey data by using smoothing function,the calculation formula is deduced,and its rationality is validated with the survey data.The result indicated that the smoothing function with favorable line types and lubricous can be widely used in other fitting problems. |
