Finally, the fluid flow of the weld pool was taken into account by increasing the heat conduction coefficient at elevated temperature.
最后采用增大热传导系数的方法，考虑了熔池内流体流动对整个温度场的影响。
It is found that the convection heat transfer plays an important part in the bulk above the return flow section and the heat conduction only rises in the bottom region.
研究表明，回流口截面以上区域传热以对流方式为主，底部区域则主要是逐层导热。
By use of the heat conduction equation in a moving medium, the analytical solution of the temperature distribution and heat flow distribution and its computational results are obtained in this paper.
本文从热传导方程出发，得到了大洋中脊下岩石层温度分布的分析表达式及数值计算结果。
