Results show that when the cross-sectional areas and lengths L of tubes remain constant, the molecular flow transmission probabilities of regular polygon tubes increase and approach those of cylindrical tubes with an increase in the number of sides, and any regular polygonal or cylindrical cross sections tubes have nearly the same transmission probabilities within 2.8% of maximum difference in the range of L ¡Ü100 (the cross-sectional area of each tube is  ).
