A new method is introduced,which researchs on automatic search of independent and closed loops or connecting tnaverse,and automatic calculation of closed error in leveling network.The method turns the function model of adjustment of indirect equations into the function model of adjustment of condition equations.With all information of condition equations,we can produce independent and connecting or close loops,and calculate closed error quickly.Comparing closed error with limit error,we can well inspect and delete gross error.Finally,based on program realizction,and illustrations are given to show that the algorithms are valid and effective.
