| 摘 要： | 气动动态实验记录中，往往包含有各种类型的干扰，有时会掩盖准确的气动结果，因而针对各种“干扰”的成因与机理，采取有针对性的数值处理方法才是正确的，有效的。本文介绍双频率非线性模型数据拟合方法的一种应用研究情况。

| Abstract: | In dynamic aerodynamic test recordings,various kinds of the interference are often included,which would sometimes cover up the correct aerodynamic results.So it becomes correct and effective to adopt data processing methods directed against these interference formation causes and the mechanism.In this paper,an application of a data fitting method for a both frequency nonlinear parameter model is introduced. |
