摘　　要：从函数模型和随机模型两方面定性地分析了粗差对平差结果的影响 ,对含粗差的观测量的分布情况 (污染分布 )进行了详细推导 ,并得出结论From the numerical model and stochastic model, the influences of adjusted result reduced by outlier are qualitatively analyzed. We educe the infectant distribution of observations which include some outliers and draw a conclusion: in some special hypothetic presupposition, the observations which include some outliers can be simply expressed as the form of normal distribution. This perceive will do much good to the outlier processing.
