1·Diatoms already secrete silica by exocytosis-a biological process by which cells direct secreted material outside the cell walls.
硅藻已经通过胞外分泌二氧化硅，这是细胞直接把物质分泌出细胞壁的一个生物过程。
2·The fluid that Armour Holdings worked on is a liquid polymer containing nano-engineered particles of silica, though BAE is coy about the details of what it is using.
装甲控股公司研制的剪切增稠流体是一种含有二氧化硅纳米颗粒的液体聚合物，BAE对其细节闪烁其词，不愿过多透露。
3·XPT, as it is called, is a roughly 2cm-thick sheet of silica particles glued together with a strong, heat-resistant resin.
因为被称为XPT材料，是一个大约2厘厚米的二氧化硅粒子的薄板，与强大的耐热树脂粘在一起。
4·The colorful effect is due to the diatom's silica cell wall, which encases the organism like a glassy shell.
它的五颜六色效果是由于硅藻的像玻璃外壳包围着机体的二氧化硅细胞壁。
5·They took something called rice husk ash: the leftover husks from processing rice is burned for energy, and the ash remains. It's high in silica and carbon.
他们用到了稻壳灰(也就是稻谷脱粒之后焚烧稻壳剩下的灰烬，其中富含二氧化硅和碳)，经过简单处理后开发出一种制造隔热板的新材料。
1·The commercial product however, containing silica and silicates, has a positive effect.
然而含有硅石和硅酸盐的工业品都有肯定的效果。
2·At ordinary temperatures silicon is impervious to air, but at high temperatures it reacts with oxygen, forming a layer of silica that does not react further.
在常温下，硅不和空气反应，但是在高温下它和氧气反应，形成一层硅石，不再继续发生反应。
3·So the research of producing the high pure quartz with the silica mineral substitutes for natural quartz is imminent.
