摘要： 研究并讨论了用于热传导分析有限元解的精细积分算法，算法很好地克服了传统方法求解时的单调性问题，且对空间离散后所获得方程的解是解析的，因而算法的解将具有“拟解析解”的意义，论文证明了算法单调性．

Abstract: The precise integration method for the finite element solution of heat conduction problems is studied in this paper. The monotonous property of the method is discussed. From accuracy analysis, it is obvious that the solution obtained by the new method is analytical for the equations derived by the space discretization of the original governing equations. So the solution obtained by the new method could be called quasi analytical solution, and the new method is very useful for the numerical solution of some...
Key words: heat conduction, numerical method, precise integration
