摘　　要：根据薄板弯曲自由振动理论 ,用振动法测定了 HP- Nb服役材料和未服役材料的弹性模量 ,据此确定了炉管蠕变损伤沿径向的分布状况。The elastic modulus of post service and new HP Nb materials were measured according to free vibration theory of sheet bending. The radial distribution of creep damages of furnace tubes was determined in terms of elastic modulus variation.

关 键 词：炉管 蠕变损伤 弹性模量 频率 振动测定法 化工机械
