| 摘 要： | 建立了单脉冲激光加热下材料温度场的三维和一维理论模型，并将其进行比较，存在较大的差异。通过改变多种参数对三维模型进行研究，给出何时三维模型可以用一维模型代替，以及用无限大边界条件下得到的三维温度场模型来处理实际问题的不足。

| Abstract: | The paper builds 3-D and 1-D theoretical models of temperature field of a material heated by monopulse laser.The greater difference is found by comparing the 3-D model with the 1-D one.This paper makes a study of the 3-D model by changing various parameters,gives when the 3-D theoretical model can be replaced by the 1-D one,and shows the 3-D model of temperature field,of which boundary is infinite is incomplete in coping with practical problems. |
