摘　　要：直接求解导热方程对具有自适应热源的可控式热隐身技术进行数值研究,探索热流控制方法及隐身效果,推导出均匀背景下二维对称截面热斗篷热隐身区域自适应热源分布的通解.仿真结果表明:对于任意对称截面斗篷,自适应热源都能使得扰动后的温度场很好地恢复到背景温度场,达到热隐身的目的.A method of directly solving the heat conduction equation is used to numerically study a controllable thermal cloaking technology with adaptive heat source.We explore heat flow control method and cloaking effect,and deduce general solution of distribution of adaptive heat source in the thermal cloak region with two-dimensional arbitrary symmetrical section under uniform background.Simulation results show that for a cloak with arbitrary symmetrical section,the adaptive heat source makes disturbed temperature field turn to the background temperature field and achieves the purpose of thermal cloaking.
