| 摘 要： | 风洞天平校准常用单元校法及多元校法。为提高天平校准公式的准度，试用复合法进行天平核准的数据处理。复合法就是在多元校数据处理时使用单元校得到的主体项系数或主体项系数和一次干扰项系数来拟合天平的校准公式。本文试比较几种数据处理方法的效果。

| Abstract: | The multi-component calibration and single-component calibration are usually used for wind tunn l balance calibration.To improve the accuracy of balance formula,we use the composite method in which main coefficient or linear interaction coefficient of single component calibration is used for multi-component calibration data processing. A comparison of methods of data processing is presented in this report. |
