| Abstract: | According to the characters of temperature field, for example, unsteady, anomaly form of laneway, inhomogeneous rock and anisotropy, the theory to calculate temperature field by finite element method is researched. How to deal with the boundary condition and anisotropy is analysed. A method for partition of elements automatically by computer is put forward. as an example, two real temperature are calculated by computer program, which can validate the correctness of the method in this paper. According to the result of calculation, the basic law of temperature changed with time and space is analysed. |
