摘　　要：推导了间接平差模型转化为条件平差模型的矩阵运算方法,用条件平差法的独殳最小闭合环对水准网做初步检查然后采用完全枚举法,全面搜索水准网的全部闭合环,再对水准网进行彻底的质量检查实践证实.基于完全枚举法的闭合差检查法具有更严格、更彻底的粗差探测功能.The matrix operation method of transforming the indirect adjustment model into the conditional adjustment model is derived,and the independent mini mum closed loop of the conditional adjustment method is used to preliminarily check the leveling network.Then,the complete enumeration method is used to search all the closed loops of the leveling network,and then the quality of the leveling network is checked thoroughly.Practice has proved that the closure error checking method based on complete enumeration method is more strict and thorough in gross error detection.
