1. Devitrification. The process in which a glass (noncrystalline or vitreous solid) transforms to a crystalline solid. 玻璃（非晶的或玻璃质固体）转变为晶体的一种工艺。
2. The results indicate that the SiO2 matrix exists in form of noncrystalline state, and the silver nanoparticles distribute in the matrix homogenously. 结果表明，基质SiO2（二氧化硅）以非晶态形式存在，银纳米粒子均匀地分布在基质中；
3. The ratio of the magnitude of an applied shear stress to the velocity gradient that it produces; that is, a measure of a noncrystalline material's resistance to permanent deformation. 剪切应力数值与其产生应变速率的比值叫粘性，用来衡量非晶材料抵抗永久变形的能力。
