| 摘 要： | 提出采用一种新的广义延拓逼近法,来实现煤矿通风机高精度特性曲线的拟合。实例的拟合结果表明:与最小二乘拟合法和三次样条插值法相比,广义延拓逼近法在相同的插值次数条件下,具有更高的拟合精度。

| Abstract: | Represents a new kind of generalized extended interpolation method to realize the high precision fitting of characteristic curve of fan. The fitting result of a practical example shows that generalized extended interpolation method can implement higher precision fitting compared to those by using the least square method and cubic spline interpolation method under the same interpolation conditions. |
