| 摘 要： | 本文讨论了Ｇ－Ｍ模型下一次范数最小ＬＡ平差和最小二乘ＬＳ平差各量的表达形式。利用帽子矩阵Ｈ的性质，首次导出了ＬＡ平差和ＬＳ平差残差之间的关系。利用它们的关系可将ＬＡ平差结果转化为ＬＳ平差结果。 |
| 关 键 词： | 测量平差，最小二乘法平差，残差最小残差绝对和平差，Causs－Markov模型，转换 |

| Abstract: | The expression forms of adjustments of LS and LA with G-M model are discussed .Based on the characters of the bat matrix,the relation between residuals of Ls and LA is derived. The results of LA can be transered into the results of LS by making tise of the relation. |
| Keywords: | surveying adjustment adjustment by least squares residuals adjustment by minimizing the sum of absolute residuals Causs-Markov model Transform |
