The spline finite element procedure is used in space domain and the state space technique in time domain respectively.
对空间域采用混合样条元法，对时间域采用现代控制论中的状态空间法。

The method to calculate temperature profile is to combine finite difference of time with finite element of space.
温度场的计算采用时间域上的有限差分及空间域上的有限元相结合的方法。
