用激光散斑研究水平放置方形平板周围空气的空间对流温度场

Laser speckle photography to measuring the natural convection temperature field of a squre plate

本文利用激光散斑法研究水平放置方形平板周围空气的空间对流温度场，根据物体的空间对流性，采用回形空间分区，只需拍摄一张激光散斑图，计算出了对流场的温度分布，其结论与其它测量结果一致。

The laser speckle photography to measure the convection temperature field of a square horizontal plate is discussed in the paper.According to symmetric of the plate,the space convection temperature field may be calculated from only one speckle photograph with dividing convection space into temperature sheathing one-in-one square zones.The result is consistent with that of laser interference.
