摘　　要：概述了国内外蠕变损伤的检测方法及现状,分析了金属材料在蠕变过程中损伤程度与电阻率之间的关系,提出了蠕变损伤检测的一种方法,对利用恒流源伏—安法测电阻。Measuring method and present situation of creep damage are summarized. The relations between creep damage degree and resistance are analysed in creep process of metal material. A measuring method of creep damage has been put forward. The feasibility of judging the degree of creep damage is analysed and described in constant current power V A method measuring resistance system.
