中文摘要：
以生产线玻璃配方为研究对象，利用旋转式高温粘度计测定了E玻璃的高温粘度-温度曲线，研究了玻璃网络形成体（B2P3、SiO2、Al2O3）、网络中间体（TiO2、ZnO）和网络修饰体（CaO）对E玻璃高温粘度的影响。结果表明，在E玻璃中，B以【BO3】三角体的形式存在，Al^3＋【AlO4】四面体形式，作为网络形成体存在；随B2O3、含量的增加，熔体粘度逐渐降低；用0．5％SiO2替代0．5％B2O3玻璃粘度有很大的上升；用0．5％Al2O3替代0．5％B2O3玻璃粘度几乎没有变化；网络中间体TiO2、ZnO起降低熔体粘度的作用；网络修饰体CaO可以在一定程度上降低熔体粘度。
英文摘要：
The high-temperature viscosity of E-glass was tested by rotating viscometer. The relationship between the high-temperature and its composition was researched. The changes of viscosity of glass melt with components （network former, intermediate former, and modified cation） were investigated. The results showed that B existed as [BO3] unit, and Al3＋ existed as [AlO4] unit. The viscosity decreased with the content of B2O3 increased. When 0.5%B2O3 was instead of 0.5%SiO2, the viscosity of melt increased to a great extent. But the viscosity was changeless with 0.5%Al2O3 instead of 0.5%B2O3. The intermediate formers （TiO2, ZnO） took effect of reducing the viscosity. The modified cation （CaO） could decrease the viscosity to a certain extent.
