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。
This paper reports two newly derived formulas for calculating the number of triangles (T): T = L ~ 2 / l ~ 2 and T = 1.45 (r ~ 2 / l ~ 2) where L is two penton shell The distance between the particles, l is the distance between any two adjacent shell particles, r is the radius of the virus nucleocapsid. The formula has been verified and applied. Of particular note is the formula: = 0.83, which closely correlates the triangulation fraction (T), the virus volume, and the distance between lids (l), and unifies all icosahedral capsid parameters At a constant of -0.83.
