Plato conjectured each of these elements to be made up of a certain Platonic solid: the element of earth would be a cube, of air an octahedron, of water an icosahedron, and of fire a tetrahedron .

In the Antibook version I wrote a selection of poems around the Icosahedron, and in the Antiposter I just used the book title: 'Antipoems'.

在Antibook中，我在20面體上寫了一些選自那位詩人所寫的詩句欧美粉嫩泬无套在线观看；而Antiposter深夜在线，我則采用了Parra詩集的標(biāo)題「Antipoems」。

It appears as a single-shelled icosahedron with 112 characteristic two-layer spikes.

Apart from translating the book and poster into the Icosahedron I created a traditional version for each piece, a conventional bound book and a flat poster, with exactly the same 30 pieces that form the structure.

When the cooling rates are 1.0 × 10^14 K/s and 1.0 × 10^13 K/s, the amorphous structures are formed mainly with the 1551 and 1541 bondtypes or polyhedron basic cluster （ 13 1 10 2） and icosahedron cluster （ 12 0 12 0） in the system.

For both projects I analysed their essence and translated their concepts into an Icosahedron; a modular Origami shape made from 20 equilateral triangles meeting at each 12 corners.

在這兩個(gè)企劃中，我分析了書和海報(bào)的本質(zhì)欧美系列黄色视频，并將其概念轉(zhuǎn)化為一個(gè)20面體欧美一级A片在线播放器，以日式的摺紙手法摺成，完成之后會有20個(gè)等邊三角形落在20面體的12個(gè)角上国产一区你懂的。

In Plato's "Symposium", Aristophanes argues that the origins of love lie in the search for symmetry, while Pythagoras and Theaetetus—who discovered the icosahedron, the geometric shape with 20 triangular faces—explored the symmetries of geometric figures.

在柏拉圖的《會飲篇》中99综合色，阿里斯托芬提出愛的緣起就在于對對稱的尋覓，而畢達(dá)哥拉斯和發(fā)現(xiàn)由二十個(gè)三角形面組成的二十面體的泰阿泰德則探究幾何形體的對稱51国产偷网站。

On the basis of on the analysis of current spherical spatial data structure, the clew of the spherical spatial basal subdivision mode which uses Snyder equal area projection on the truncated icosahedron DGG is discussed, and then global multi-resolution overlay is obtained by subdividing hierarchically on the initial projection plane according to the hexagonal grid.

It has been found that during the spark plasma sintering process, under the condition of large current, short sintering time and lower sintering temperature, the metastable icosahedron quasicrystal phase in primary powder particles is kept. And the strong discharge plasma among particles can decompose or break the oxide film on the primary powder's surface, resulting in the increment of their combination strength. So the as-prepared bulk alloy possesses high density and ultra-high strength.

The results of XRD (X-ray diffraction), SEM show that the Al-Cu-Fe quasicrystalline coating is dense and uniform, by preparing from Al70Cu20Fe10 powders with particle size of 325 mesh (4.5μm). After annealing under vacuum condition of 800℃ for 2 hours, it is observed that the icosahedron phase is the major phase together with a few β-Al phase.
