半无限大物体中的移动热源导热

Heat Conduction due to Moving Heat Sources in Semi infinite Body

利用镜像法和热源函数法对移动热源在半无限大物体中的热传导问题进行了分析，得到了壁面绝热和壁面恒温时常功率平面移动热源在半无限大物体和表面有散热的半无限长细杆中形成的温度场的精确解。

Combined image method with heat source function method,heat conduction due to moving heat sources is analysed in semi infinite body and cylinder with heat exchanging on its surface.The distribution of temperature is obtained when the wall temperature is constant and the wall heat flux is zero.The result is useful for engineering calculation.
