摘　　要：经典平差处理非线性模型时,一般将非线性模型按Taylor级数逼近理论,将其线性化。但在精密工程测量数据处理过程中,需要克服由此产生的模型误差,以提高观测成果的精度。本文在分析线性模型与非线性模型数据处理方法的性质的基础上,结合精密工程测量中常用的边角控制网,对迭代数据处理方法进行了详细探讨。Nonlinear model is linearized according to Taylor＇s theorem in traditional adjustment,which would result in model errors that should be avoided especially in high precision engineering in order to improve the quality of the calculations.Through data processing of a triangulation network,an iterations method based on the analysis of the different properties of linear and nonlinear models has been studied in details.
