Abstract :
A simulation program of different shapes honeycomb was made to analyze its radiation restraining performance based on Monte Carlo method. The long-wave radiation restraining coefficient was defined and calculated. The results derived from two judge conditions were averaged and regarded as final coefficient values. The results showed that increasing aspect ratio could increase the coefficient, but the change speed slowed down with the increasing of it. Glass circular tube with larger wall thickness had a smaller coefficient, while polyester film with larger wall thickness had a larger coefficient. With the same wall thickness, the long-wave restraining coefficient of triangle polyester honeycomb was smaller when aspect ratio was small. But when aspect ratio increased, coefficient of triangle polyester honeycomb would exceed that of square polyester honeycomb due to faster increasing speed. For large aspect ratio, the triangle honeycomb was a better choice than square honeycomb.
