| 摘 要： | 在控制网顾及起始数据误差影响的数据处理时,关心的是如何充分利用已获得的经典平差(间接平差)结果来顾及起始数据误差影响以及起始数据误差对未知参数影响是否显著和如何估计这种影响的大小等问题。本文对这些问题进行了近控讨,提出了顾及起始数据误差影响的最优间接平差方法,通过对一个控制网的分析,表明这种方法不仅具有理论价值,而且具有实践意义。

| Abstract: | In dealing with the data of control net in reckoning the influence of initial data errors, the concerned problems are how to fully utilize the obtained classical adjustment (adjustment by parameters) to reckon the influence of initial data errors, whether the influence on the unknown parameters is remarkable or not, how to estimate the influence and so on. The paper discusses these and points forward an optimal method of adjustment by parameters in reckoning the influence of initail data errors. By analysing an example of a confrol net it is shown that this method has not only theoretical value but also practical significance. |
