【摘要】 变形监测网平差的主要方法是秩亏平差法或拟稳平差法。本文基于抗差估计原理，首先推导了秩亏平差模型的抗差解式和拟稳抗差解，并推导了普通秩亏抗差解与拟稳抗差解之间的转换关系。使得拟稳抗差估计的解算简便直观。更多还原

【Abstract】 The main adjustment methods. for deformation monitoring networks. are free network adjustment or quisi-stable adjustment. Based on robust estimation principle. the robust estimators are derived for free network adjust ment and quisi-stable adjustment. A transformation expression is established between the robust free network adjustment and robust quisi-stable adjustment. By the transformation expression, the calculation of robtlst quisi-stable ad Justment will be simplified.更多还原
