线性空间与非线性函数空间测量平差效果比较

摘要

The nonlinear adjustment and data processing theory is one of the main problems in researches. In the way ofadjustment with the first and second order term of expanded nonlinear function inconsideration and the way of nonlinearadjustment in the fields of nonlinear to do the same adjusment, by comparison of its results, it is concluded that the ad-justment which considered the second order term of expanded nonlinear function costs more than the adjusment whichconsidered the first order term of expanded nonlinear function, and stressed is put on the possibility of constructing theoryof adjustment and data processing in the space of nonlinear functions.%非线性函数空间的测量平差与数据处理理论是当前理论界研究的一个重要课题．用顾及一阶、二阶泰勒项的线性平差方法及非线性函数空间的平差方法对同一平差问题进行研究，通过比较其平差效果，结果表明顾及二阶泰勒项的平差方法性价比是不合理的．
