摘要: 作者回顾了过去20年中和同事们对玻璃结构所做的工作.一些重要的结论指出,玻璃作为非晶态固体,它的结构中可包含两种类型的集聚原子或原子团,即无序的基团和有序取向(一维优先)的基团.此外,尚有少量(可忽略不计)纳米晶存在于真实玻璃中,这种特点就是与理想玻璃相异之处.为了把真实玻璃和理想玻璃说得简明些,在文中列出了表格,为了使玻璃结构及其本质更具有理性的科学认识,作者在文中特别设计了石英玻璃结构示意图.

Abstract: The author reveiws the works on study of the structure and nature of glass, done by the author and his colleagues,
in the past 20 years. Some important conclusions indicated that glass as the non-crystalline solid, its structure may contain two types of agglomerated
atoms or atomic groups, i.e., disorder groups and ordered orientated (one dimensionally prefered) groups. In addition, a little quantity (negligible)
of nano-crystals may appear as a particular role in real glass and this characteristic may distinguish it from ideal glass. A table is shown for
interpretating more briefly. A schematic diagram of fused silica glass structure is designed by the author and provided here, so, it may express the stucture and nature of
glass with its reasonable scientific recognition.

Key words: real glass and ideal glass, ordered orientation and disorder, crosslink and agglomerate, nano-crystal
