摘　　要：本文从观测值中含有多个粗差的平差值入手，采用文献[1]中的F－T检验法剔除多个粗差，导出了剔除多个粗差后的平差值转换公式．与文献[2]中的转换公式比较可知，本文所提出的是一通用公式，而文献[2]中转换公式仅是文中的特冽。文中的其例说明，这一转换公式在理论上是严密的，实用起来方便、可行．This paper starts from the adjusted value containing sereral outliers in the obscrvation value,de tecte outliers adopting F-T examination method in reference[1],derives the transformation formula of adjusted value after detection of outliers. As compared with the tramformation formula in reference[2],it can be seen that the formula presented in this paper is a general one and that the transformation formula in reference [2] is only a special case. The calculating example in this paper manifests that,this transforma tion formula is rigorous in theory and convenient and feasible in practice.
