| 摘 要： | 固体表面温度和热流的直接测量在某些情况下是很困难的。使用“过去的”和“将来的”测量时间 ,引入稳定矩阵的概念 ,抑制了导热反问题的误差放大作用。通过埋设在固体内部的热电偶的温度测量 ,同时对固体表面的温度和热流进行了有效估算

| Abstract: | It is difficult to measure the surface temperature and heat flux directly in some cases. Past and future measurement times are used in the paper, and a stabilizing matrix concept is introduced. The magnified error effect of IHCP is inhibited. Simultaneous estimates of the surface temperature and heat flux are obtained from measurements taken by some thermocouples embedded within the body. |
