摘要
介绍通用曲线面拟合软件中用到的一些主要技术和软件的主要功能,并以某台轴流式风机的QNH特性曲线为例,用该软件进行曲面拟合和二维插值,计算结果表明,用该软件进行的计算达到了较高的精度,完全满足工程需要。
This paper introduces some main techniques and functions of the universal curve fitting and surface fitting software. The QNH performance curve of an axial fan was taken as an example, where the software is applied to do the surface fit and two dimensional interpolation. The result shows that the calculation using this software has reached a high level of accuracy, and completely meets the requirements of the engineering.
