| 摘 要： | 介绍一种基于灰色系统理论的粗大误差判别方法。该方法对于数据少或分布规律不明的情况能给出准确的结果。以核磁共振稳态吸收实验中磁场强度与励磁电流的线性拟合为例，使用灰色判别方法进行粗大误差的判定和对比，说明该方法在物理实验异常值剔除中的高效性和实用性。

| Abstract: | An introduction of the method for detecting gross errors based on the grey system theory. The meth- od can even provide accurate results when the distribution of the data is unknown and the sample size is small Taking the linear fitting of BI in a Nuclear Magnetic Resonance experiment as an exarnple,the grey method is used to detect the gross errors, which shows the efficiency and practicability in physical experiments. |
