From the fact that geometric figure closures are not independent in the engineering surveying, the generalized Ferrero formula is derived in this paper to be m_o~2 = (W~TQ_(WW)~(-1)W) / N and its application in Triangulation has been discussed.

• 本文从工程测量中几何图形闭合差相关这一客观实际出发,导出了广义菲列罗公式为 m_o~2=W~TQ_(WW)~(-1)W/N并就其在三角测量中的应用进行了讨论。
