摘要
本文尝试从梯度功能材料热传导问题的控制方程出发，证明了梯度功能材料在其物性系数为坐标变量约函数时的三维热传导问题的泛画是存在的，导出了相应约泛函，建立了相应的变分原理．
Starting from the governing equation for temperature field of functionally gradient material, this paper proves that the funcional for the problem of three-dimensional heat conduction exists when the material properties are only described by a function of the coordinates. As a result, the functional from the equation is derived, and the associated variation principles are established.
