建立了空间目标的热平衡方程，利用节点网络法求解其表面温度场分布；

The heat balance equation of space target is given and the temperature distribution of space target is got by node network.

然后引入作用较大的高阶广义节点形函数，扩充广义刚度矩阵，并求解新的整体平衡方程，得到更高精度的数值解。

Then, those useful generalized nodes are selected, and the generalized stiffness matrix is enlarged. A more accurate numerical solution can be obtained after the new equilibrium equations are solved.
