| 摘 要： | 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.

| Abstract: | 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 distance
between any two adjacent capsomeres, r the radius of viral nucleocapsid. The formulas have
been verified and applied. It is worth noticing that the triangulation number, viral size and
distance between capsomeres are fully connected by the formula r/(Tl)~(1/2) = 0. 83, and the capsid
parameters of all icosahedral viruses are unified in one constant, 0.83. |
