【摘要】 介绍脉冲热像检测中由峰值时间求缺陷深度的方法,对热传导性能好的材料,从红外热像时间序列难以捕捉到峰值时间。为此提出了一个既能避开峰值时间又能被红外热像仪探测和记录的新参数,从而达到测量缺陷深度的目的。更多还原

【Abstract】 Pulse thermographic method for determining defect depth through peak time was introduced. It was difficult to catch the peak time of the materials with good heat conduction. So a new parameter was put forward for determining defect depth which could avoid peak time and be recorded by thermographic instrument.更多还原
