摘　　要：在红外定量缺陷检测领域,现有的理论方法大多会带来较大的误差。另外,利用热传导方法检测缺陷的理论也仅仅停留在对表面缺陷的检测上。在表面缺陷检测的热传导理论的基础上,提出了试件内部缺陷检测的热传导理论模型。In the field of infrared quantitative defect detection,the existing theoretical methods may bring about greater errors.In addition,the theory which uses the heat conduction method to detect defects is only limited to the detection of surface defects.On the basis of the heat conduction theory for surface defect detection,a heat conduction theoretical model for detecting internal defects in specimens is proposed.
