THE DIFFUSE APPROXIMATE SOLUTION FOR STABLE AXISYMMETRIC HEAT TRANSFER PROBLEMS

对轴对称稳态热传导问题的弥散逼近数值解作了初步研究。文中的理论分析和数值算例表明，弥散单元法应用于稳态温度场的数值求解具有计算精度高、节点布置和修改灵活等优点。弥散单元法作为一种新型的边值问题数值方法具有进一步研究和推广的价值。

We have made initial researches on the diffuse approximate solution for stable axisymmetric heat transfer problems. The theoretical analysis and the numerical examples show that DEM is of great advantages in obtaining the numerical solution of stable temperature field. The diffuse approximate solution may have high accuracy,and it is convenient to rearrange the nodal points by DEM. As a new method for solving boundary value problems,.DEM deserves further study and more applications.
