本文报道新推导出的两个计算三角形剖分数(T)的公式:T=L~2/l~2和T=1.45(r~2/l~2),这里L是两个五邻体壳粒间的距离,l为任意两相邻壳粒间的距离,r是病毒核壳体的半径。对公式进行了验证和应用。特别值得注意的是公式:=0.83,它把三角形剖分数(T)、病毒体积以及壳粒间的距离(l)之间的关系紧密地联系起来,把所有正二十面体病毒衣壳参数统一于一个常数——0.83。 相似文献

The present paper reports two [new formulas for calculating triangulation number T.They are T =L~2/l~2 and T = 1.45r~2/l~2, where L is the distance between pentons, l the distancebetween any two adjacent capsomeres, r the radius of viral nucleocapsid. The formulas havebeen verified and applied. It is worth noticing that the triangulation number, viral size anddistance between capsomeres are fully connected by the formula r/(Tl)~(1/2) = 0. 83, and the capsidparameters of all icosahedral viruses are unified in one constant, 0.83. 相似文献
