摘　　要：对红外热像无损检测中各种热激励技术的特点和应用情况进行了简单介绍,并采用有限元素法分析了电磁感应热激励过程中含内圆孔管道的外壁温度分布及其在不同孔径和深度下随时间的变化关系,说明了基于电磁感应热激励的红外热像无损检测技术的影响因素和应对措施。Different thermal excitation methods in infrared thermography non-destructive test （NDT） are discussed, and the application situation is introduced. The defects on inner wall of the pipe heated by electromagnetic induction were analyzed with the finite element process. The emphasis was placed on the temperature distribution on the outer wall and the relationship between different sizes of hole depth or bore diameter and the time. Influences and response measures on the method of thermal excitation based on electromagnetic induction in infrared thermography NDT is proposed.
