| Abstract: | Based on pure Aluminum, the axisymmetric physical model of temperature field is established and we make use of center-space center-time numerical method to simulate two-dimensional temperature field and gain correlative distributing of it. According to the numerical results, they show the melted layer thickness and the first melted time, etc. |
