摘要
本文研究细长电加热体在圆筒形半透明介质中的温度响应，通过对控制非稳态导热与辐射复合传热过程的积分-微分方程直接进行数值求解，分析了热辐射对内部径向热流及温度变化的影响．模拟计算结果对热线法测量半透明介质导热系数的研究具有理论指导意义。
The temperature response of a thin hot-wire immersed in cylindrical semitransparent medium is studied in this paper. The full integro-differential equation governing the transient combined conductive-radiative heat transfer is solved directly by numerical method. The radiative colltribution to the heat flux and the effcts of radiation on the temperature rise areanalyzed through computation. The results of numerical simulation is helpful for establishing a new simplified model for hot-wire method.
