脉冲激光加热材料的温度场解析

Study on model about the material heated by pulse laser

对脉冲激光加热解析模型进行了修正,研究了对流换热和热辐射对样品温升场分布的影响;还对表面加热模型和体加热模型进行了比较,为研究材料热学特性提供了精确的理论依据.

Pulsed laser heating analytical model is amended. The impact of the heat convection and the heat radiation is studied by the body absorption model. The relation between the surface absorb model and the body absorb model is studied;this offers a more accurate theory to study the thermal properties of material.
