在论述热点跟踪及其传热机理时将靶材（以铝靶ＬＹ１１为例）的比热溶、热传导系数、激光的热藕合系数均考虑成温度和时间的函数，又考虑靶材在运动时将激光辐照物体时热点的建立及其稳定情况作一动态数值模拟，为热点跟踪作准备。本文只考虑激光强度未对物体造成破坏的情况下，即（Ｑ＜１０~６Ｗ／ｃｍ~２），靶材在熔化之前处于固态的热点情况。 In the discussion of hot spot tracking and its heat transfer mechanism, the target material (aluminum target LY11, for example) specific heat solution, thermal conductivity, laser thermal coupling coefficient are considered as a function of temperature and time, but also consider the target in motion When the laser radiation objects when the establishment of hot spots and its stability as a dynamic numerical simulation for tracking hot spots in preparation. This article considers only the laser intensity without damage to the object, that is, (Q <10 ~ 6W / cm ~ 2), the target before melting in the solid state hot spots.
