Also in the 3-D space, we assign the 20 amino acids to 20 vertices of the dodecahedron. By the symmetry of the dodecahedron we obtain 3-D representation of 20 amino acids, and 3-D graphical representation and the corresponding numerical sequence of protein sequences. And similarity and dissimilarity analysis based on the invariants of graphs and characteristics of numerical sequences are given for nine RNA secondary structures of RNA-3 of virus. We construct sequence phylogenetic tree of a group of cytochromes C protein.

在DNA三联体密码子表示的基础上，在半复平面上给出了蛋白质序列的非退化的2-D图形表示，同时利用复向量的主要特征—模和相位，给出了蛋白质序列的一种数值刻划，进一步在3-D空间里，把20种氨基酸分别分配给正12面体的20个顶点，根据正12面体的对称性得到了20种氨基酸的3-D表示，进而得到了蛋白质序列的3-D图形表示和对应的数字序列，并利用图的不变量和数字序列的特征比较了9种动物的神经元

However, when occurring in Mesozoic remelted granite, pyrite is featured mainly by high gold content in pentagonal dodecahedron and in its complex; low content in cubic pyrite; Au/Ag ratio between 1-2; both N and P types of pyrite present in most deposits and P type only in a few deposits.

产于中生代重熔花岗岩中时，黄铁矿以五角十二面体居多，五角十二面体及其聚形含金较高，立方体含金性较差；Au/Ag比值在1-2之间，As的含量较高(＞600×10〓)；Co、Ni的含量则较低，一般为10n×10〓；热电性以既有P型又有N型的P、N混合型为特征，少数金矿床表现为单一的P型。

分析表明，现面罩的舒适性和气密性存在较严重的问题，主要原因是面罩体造型与飞行员面型不符；新面罩的设计必须以我国飞行员的三维面型特征作为造型设计依据，并应轻便无异味。

The analyses of orbital interaction based on energy bands and DOSs indicate that there is obvious covalent interaction between Ni-O.

能量计算表明，NiO(001)面表面能小，比较稳定；NiO(111)面则表面能大，不稳定，与实验结果一致。
