The high compressive strength is obtained when the modulus of the activator viz., molar ratio of SiO2/Na2O is 1.5, and the proper content of this activator evaluated by the amount of Na2O to the high-calcium fly is 10 %. The compressive strength of these samples is 63.4 MPa when they is cured at 75 oC for 8 hours flowed by curing at 23 oC for 28 days. The main gels of geopolymer and calcium silicate hydrate, and Gismondine co-exist and bond some remaining unreacted fly ash spheres.

In each shell the spheres are hexagonally arrayed.

每一层内，颗粒是二维的六角密堆积。

A variety of ordered bulk phases, including lamellae, hexagonally packed cylinders, body-centered-cubic spheres, and a bicontinuous network structure called Gyroid are observed for diblock copolymers.

在熔体状态下，双嵌段共聚物可以自组装形成包括层状相、六角排列柱状相、体心立方球状相和双连通Gyroid相的一系列稳定有序结构。

SEM micrographs showed that the PS colloidal crystal template spheres (diameters 275±10 nm) arrayed into hexagonally close-packed layers. The synthesized 3DOM SnO2 microparticles were circularly or hexagonally porous and the thin porous walls were formed by nanocrystals of SnO2. The macroporous diameters of the 3DOM SnO2 were between (215±10) nm and the thicknesses of the porous walls was between 20～30 nm.
