| 摘 要： | 在运用图像处理的方法测量火焰温度场的研究中 ,如何从二维的累积温度场中分离出包含每个断面温度分布的三维温度场是一个关键问题。该文提出了一种利用逐次逼近方法来重建三维温度场的思路。根据辐射传递方程 ,在两个相互垂直的方向上分别获取火焰图像 ,利用逐次逼近方法求出方程组的解 ,即可求出火焰的三维温度场。图 8参 6

| Abstract: | How to reconstruct three dimensional temperature field, including their tansectional temperature distributions, with the help of cumulated two dimensional temperature fields, is a key problem in flame temperature measurements. The paper presents some ideas of how this can be accomplished by a method of successive appreximation. According to the equations of radiative transfer, if images of a flame have been abtained in the perpendicular directions, then its 3 dimensional temperature field can be formed by successive appreximation with a set of equations.
