| 摘 要： | 测量平差模型不仅包括函数模型还包括随机模型,因此要研究测量平差模型误差对平差结果的影响就要研究函数模型误差和随机模型误差二者同时的影响。本文以间接平差模型为例,随机模型误差、函数模型误差和随机模型误差三个层次研究了测量平差模型误差对平差结果影响的公式,论证了不同平差模型误差情况下的平差结果,并推导和论证了同时考虑函数模型误差和随机模型误差对平差结果影响的公式。

| Abstract: | Survey adjustment model not only contains mathematic model that is function model but also contains stochastic model,so it needs research simultaneous effect of function model error and stochastic model error.The paper studied the formula about survey adjustment model error affecting adjustment result based on parameter adjustment model,and gave different adjustment result on the condition of different adjustment model errors from three levels that are stochastic model error,function model error and stochastic model.The paper deducted and proved the formula about adjustment result considering function model error and stochastic model error at the same time. |
