摘要
本文首先研究了污染误差模型的各种具体的误差表示形式,然后研究了误差服从污染误差模型时的平差准则。指出,当误差服从污染误差模型时选择均方误差作为估计准则是合理的,并且符合传统的测量误差处理的观念。最后,推导了误差服从污染误差模型时,均方误差准则下的最佳估计。
The paper studies the practical error forms of contaminated error model at first. And then the criteria of the estimate under the contaminated error model are studied. It is showed that the minimum mean squared error is a better criterion for the estimate under the contaminated error model. At last, the estimate under the minimum mean squared error is given out and the theory of surveying adjustment based on the contaminated error model is established.
