Partialheattreatment in adoption of electric ceramic heater & overall heat treatment in heating treatment oven are included; and, overall heat treatment is recommended if the conditions permit.
The mathematical physical model is established depending on the conventional laser heattreatment technology, the partial differential equation of heat current propagation is derived.
本文以常规的激光热处理工艺为基础，建立相应的数学物理模型，导出热流传导的偏微分方程。
