摘要
根据实例计算及理论推导,分析讨论了在评定精度中顾及起算数据误差的有关问题。在附合网独立平差中,必须用不受起算数据误差影响的残差带权平方和来求m_0,而求协因数时,则应顾及起算数据的误差。
On the basis of calculating examples and proving the theory, this paper analyzes some questions of attending to the original data errors in evaluating precision. In isolated adjustment of annexed net, m_0 must be calculated by the sum of weighted squares of the residual errors which don' t affect the original data errors. But the original errors should be taken into account in calculating cofactors.
