| 摘 要： | 先通过对边界条件的实验分析,确定了对边界条件绝热处理的可行性,然后通过"模型分割"的办法,将一维理论模型在时刻的温度分布作为三维模型的初始条件,并把之后的温度变化作为三维模型圆柱体的侧面边界条件,给出脉冲红外热成像无损检测三维理论模型的一种近似解法.

| Abstract: | In this paper the feasibility of taking the boundary of the theoretical model as adiabatic is firstly studied. Then by " model separation ",in which the temperature distribution of one dimensional model at is taken as the initial temperature distribution of 3-D model and temperature evolution of one dimensional model after is taken as the lateral boundary condition of 3-D model, an approximate solution to the thermal pulse video thermography sting is given. |
