摘要
根据组合多面体理论及突角和理论,得出有12个正五边形和多个六边形构成的网壳,并计算了网壳中五边形边长与五边形外接球半径的比例关系,给出了相应的拟合公式,其相对误差不大于4.07%,据此,可根据工程需要进行多面体选型。
According to the theory of combined polyhedron and quoin summation,shells with 12 pentagons and several hexagons are derived.The ratio of side length of pentagons and radius of circumscribing sphere of pentagons is reckoned,and the fitting formula is worked out,the relative error of which isn't bigger than 4.07%.So the style of pentagons would be chose as the need of engineering.
