摘　　要：为了提高飞参发动机转速数据中野值的剔除效率,提出使用基于样本分位数原理并采用间隔取样的野值检测法能够有效识别并合理替换野值。该方法采用样本分位数方法无须进行复杂的参数及内部设置即可实现野值。对基于Savitzky-Golay滤波器的野值去除方法研究发现该方法也具有良好的野值识别能力,虽然计算量较大但通用性较强。两种方法均可有效提取出飞参数据中的野值,为后续飞参数据处理奠定基础。In order to improve the outlier elimination efficiency of flight engine rotate speed data,it was proposed that the outliers detection method based on sample quantile by using interval sampling can effectively extract the outliers without complicated parameters and internal settings.Study on the outliers elimination method based on Savitzky-Golay filter discover that this method has good outliers recognition ability.Although it is computationally intensive,it is more versatile.Both methods can effectively extract the outliers in flight parameter data,which lays a foundation for the subsequent flight parameter data processing.
