正廿面体病毒的轴长、三角形剖分数和壳粒间距之间关系的研究

The Correlation among Viral Axes,Triangulation Nuniber and Capomeres

本文根据正廿面体病毒具有５：３：２旋转对称轴特性，分别计算出各条对称轴的轴长，并相应推导出：这里ａ５，ａ３和ａ２分别是５－，３－和２－重轴的长度，ｌ是任意两相邻壳粒间的距离，Ｔ是三角形剖分数。同时对已报道过的又采用新的方法给予推导和验证，这里，是病毒等效球的平均半径。通过上述公式深入地揭示了病毒的大小、轴长与三角形剖分数和壳粒间距之间的关系。

his paper talculates the length of the 5-,3-,and 2-fold rotational symmetry axes and the derivesforuiulas from them,they are and where a5,a3,and a2 are the length of the 5-,3-,and 2-fold axes reslxctively,1 is the distaisee between any two adja-cent capsomeres,Tis trtangulation number.The formula of the that we hove reportedis derived ty the new method.These formulas connect T,a5,a3, a2,r and 1.
