摘要
介绍了部分几何形状未知的热传导反问题．通过引入辅助问题并利用积分变换方法，推导出二维、双层球壳红外ＣＡＴ通用算法，并对内表面为第三类边界条件进行了分析和讨论．通过数值实验对推导的算法进行了验证．
An inverse heat conduction problem with partially unknown geometries is presented. A general solution of IR CAT for two dimensions and two layers spherical shell is developed by introducing an auxiliary problem and using the integral transforms. The solution is analyzed and discussed when Robin condition is prescribed along the inner surface. Finally, the solution is tested by numerical experiment. The experimental results prove that the solution is feasible.
