摘要
Helmert方差分量估计是一种根据验后信息重新定权来保证观测值权值合理的方法之一,在很多方面已经得到了很广泛的应用。把Helmert方差分量估计引入跨江水准测量的数据处理中,使观测数据的权值更加合理,平差结果更加准确。
As one method for gaining the best weight by confimaing weight aftertest. Helmert variance component estimation has been applied in many facets. The paper introduces Helmert variance component estimation to the data hanaling in river- crossing leveling. This application can make the weight more reasonable, and the adjustment results more precise.
