摘要
把蜂窝陶瓷每一单孔看成非等温空腔,进行热辐射数值计算,结果表明,非等温空腔具有定向辐射之功能,而所需空腔的实际深度相对很小。
Numerical computation is carried out for the thermal radiation of honey-combed ceramics, regarding each single cavity as of nonisothermally walled one.The results indicate that such cavities have a function of directional radiation,and in practice the depth of cavity required is very small.
