摘　　要：对复合材料的热传导方程进行数值分析，采用了三维的Ｄｏｕｇｌｅｓ格式及Ｃ－Ｎ格式混合求解，得到复合材料的温度场．解精度高（二阶），绝对稳定，收敛快，可为复合材料制品工艺控制提供理论依据，对减小热残余应力，克服爆瓷起积极作用．Glass-Lined material, which is sintered at high temperature, has different coefficients of thermal expansion, which is due to the residual strees created in the process of cooling the material to the viscoelastic material. However, self-cracks could be triggered in the stress affected area of buffer, when the stress exceeds the strength limit. Numerical analysis is adopted to solve the heat-transfer equations of glass lined material. Three-dimension Dougles and C-N method are used to gain the temperature field suited to cooling process of the the glass lined material. Tests show that the theory and method advanced in this paper are applicable to the process control of glass lined products, The numerical analysis is available for decreasing the residual stress and getting rid of the glass-cracking.
