glass composition

Analysis and comparison of the form of crystallization peak and the temperature difference(△ T) between crystallization temperature Tx and glass transition temperature Tg were made to determine the thermally stable glass composition zone in the glass-forming region.

以玻璃析晶峰的形状以及玻璃析晶温度Tx与玻璃转变Tg的差△T为参数，确定了具有较好析晶稳定性的组成区。

The relations between glass composition and refractive index, dispersion, density, transformation temperature, softening temperature, thermal expansion coefficient, thermal optical coefficient are studied.

研究了上述系统玻璃折射率、色散、密度、轻变温度、转化温度、热膨胀系数、热光常数和成份之间关系。

Abstract This paper gives an introduction to some key techniques about the manufacturing of high silica glass fiber, such as basic glass composition, melting furnace structure, electric melting technique for high boron glass, acid leaching of glass fabrics, and etc.

本文阐述了高硅氧玻璃纤维的制造工艺及技术关键问题，如基础玻璃成分、窑炉结构、高硼玻璃电熔技术、织物酸沥滤的研究等。

The so called "activity of the blending material" shows the extent of this dissociation which depends on glass composition and structure, especially the content of Al_2O_3 and the coordinate condition of Al~ ( 3+).

所谓混合材的活性，是表示这种离解的难易程度，它取决于玻璃的成分和结构，其中Al2O3的含量、配位状态具有更重要的意义。
