摘　　要：透明蜂窝结构的透过率是其重要性能之一。该文的工作基于Hollands简化方法将透明蜂窝结构单元 (小孔 )假想为一个由不透明材料围成的腔体 ;再根据几何光学原理将腔体内光线的三维反射传播过程转化为两个假想的平面在单元内不断反射传播的过程。该方法可简化透明蜂窝结构光学透过率的计算。所得计算结果与经典的MonteCarlo法相接近 ,而过程则大大简化。The transmittance of honeycomb structure is one of most important performance. Based on Hollands' idea and geometric optics,the transmittance of honeycomb was found to be equal to the transmittance of imagined honeycomb cell made up of opaque walls. By further investigation of the transmittance of honeycomb with rectangular cell,it was found that the three dimension reflection of beam in the cell can be simplified into the reflection of two imaginational plane in the cell.The model simplifies the method which counts the reflection times of ray in the cell,and can be used to calculate the transmittance of honeycomb structure.It is quicker and easier to calculate the transmittance of honeycomb structure compared with Monte Carlo method.
