The theory of Caspar and Klug (1962) for the structure of isometric viruses has been generalized to the case in which the identical repeating unit is composed of n nonidentical polypeptide chains. This modified theory accounts for the structure of picornaviruses, the lambda phage head, cowpea mosaic virus, and phiX174, while at the same time conserving the principle of having identical subunits in identical environments. Furthermore, the modified theory suggests amending the triangulation number to T[n] for capsids with n nonidentical polypeptide chains as the repeating unit.
卡斯帕和克鲁格（1962年）提出的等轴测病毒结构理论已推广到相同重复单元由n条不同多肽链组成的情况。这一修正后的理论解释了小核糖核酸病毒、λ噬菌体头部、豇豆花叶病毒和φX174的结构，同时保留了在相同环境中有相同亚基的原则。此外，修正后的理论建议将具有n条不同多肽链作为重复单元的衣壳的三角剖分数修正为T[n]。
