Did it when I was four. It's an icosahedral dye floating in tinted blue water.

我四岁时就做过了，是个二十面体染色物在蓝水里漂浮。

There are 3 types of shapes: helical, icosahedral, and complex.

螺旋对称、二十面体对称与复合型。

And they can have 3 types of shapes: helical, icosahedral, and complex.

他们可有三种形状：螺旋对称、二十面体对称与复合型。

Finally, the complex viruses have a combination of icosahedral and helical shape and may have a complex outer wall or head-tail morphology.

最后，复合型病毒兼具二十面体和螺旋对称结构，可能有复杂的外壁或头尾形态。

During the endocytosis process, the icosahedral capsid breaks open, allowing the single stranded RNA of Rhinovirus to gain access to the host cell cytoplasm.

在胞吞过程中，二十面体衣壳破裂，使鼻病毒的单链RNA能够进入宿主细胞的细胞质。

They are naked viruses, about 30 nanometers in diameter, and they're surrounded by an icosahedral capsid, which is a spherical protein shell made up of 20 equilateral triangular faces.

它们是直径约30纳米的裸露病毒，被二十面体衣壳包围；二十面体衣壳是由20个等边三角形面组成的球形蛋白质壳。

Human herpesvirus 8 is a large double stranded linear DNA virus surrounded by an icosahedral capsid, which is a spherical protein shell made up of 20 equilateral triangular faces.

人类疱疹病毒8型是种巨大的双链DNA病毒，其外由一个二十面体的衣壳包围，其衣壳是由20个等边三角形组成的球状蛋白壳。
