摘　　要：测试—故障依赖性矩阵(D-矩阵)是大系统装备故障诊断的基础和关键。针对目前TEAMS软件在舰船武器装备综合诊断应用中存在的D-矩阵数据不开放问题,本文借鉴EXPRESS诊断推理模型描述方法,设计了易在建模和算法间共享或交换的D-矩阵XML模式;并针对TEAMS软件,分析了基于多信号流模型的D-矩阵XML文档生成方法;最后以某超短波设备为例,对基于D-矩阵XML描述文档的诊断应用过程方法进行了详细分析。该方法增强了TEAMS软件的适用性,可解决D-矩阵数据在不同应用领域的共享和可交换难题。Dependency matrix （D-matrix） is important to fault diagnosis for complex weapon system. With the problem occurring from TEAMS software used in integrated diagnostic of shipboard weapon equipment, a new XML schema for D-matrix was proposed according to the diagnostic inference model defined in MIL-STD-1232; the method to get a XML instance document for D-matrix from a TEAMS＇ multisignal model was analyzed; an ultra-short wave equipment system-level function is selected to validate the method proposed. With this way, it can make D-matrix data to be co-shared and exchangeable in various fault diagnostic domains.
