摘要
提出了完善和统一的自由网平关模型 ,克服了一般模型的未知参数理论值 x模糊 ,其估值 x解不定 ,x是否无偏估计量等问题 ;适合于各种参考系时的平差计算 ,这证明了各种平差方法属于同一平差理论。对解算公式 ,无偏估计量 ,坐标转换等进行了推证。对参考系的含义提出了见解。
In the paper, the perfect and indentcal adjustment model of free networks is proposed. The model overcomes some problems of unknow parameters of general model, the problems include the theoretical value x fuzzy, estimate indefinite, whether unbiased estimation etc.. The adjustment calculation applicable to various reference systems proves that various adjustment methods belong to the same adjustment theory. The calculating formulas, unbiased estimation values, coordinate transformation etc are derived. Some views on the meaning of reference system are propsed.
