根据感应加热原理，利用ANSYS有限元软件，确定了电磁场、温度场的数学模型和求解的边界条件；根据模拟计算结果，分析了电流密度和频率对电磁场和温度场的影响。通过曲面相应法，确立感应加热的温度回归模型，分别建立温度与电流密度和频率的关系方程，并根据电流密度和频率的一阶微分方程，得出了电流密度对温度变化率影响较大。

The mathematical models of electromagnetic field and temperature field are determined, based on the principle of induction heating, via the ANSYS FEM software. The effect of the current density and frequency of the coil on electromagnetic field and temperature field is analyzed according to the simulation results. With surface corresponding method, the relation equation between temperature and current density and frequency is built. The current density has larger influence on temperature gradient according to differential equation of first order of current density and frequency.
