我们报告了第一个不需要知道玻璃在熔炉中的粘度(或温度)的孔拉伸纤维的分析性描述。该模型给出了一个孔的大小的表达式，该孔与其他孔隔离开来，与纤维的外径相比很小，但包括了表面张力、压力和任意粘度分布的影响。粘度的影响由纤维拉伸张力表示，与粘度不同的是，纤维制造者在实践中可以很容易地测量到它。该模型在不依赖任何可调的拟合参数的情况下与实验吻合。(C)2013年美国光学学会
We report the first analytical description of the drawing of fibres with holes that does not require knowledge of the viscosity (or temperature) of the glass in the furnace. The model yields expressions for the size of a hole that is isolated from other holes and small compared to the outer diameter of the fibre, but includes the effects of surface tension, pressurisation and arbitrary viscosity profiles. The effect of viscosity is represented by the fibre draw tension which, unlike viscosity, can readily be measured in practice by the fibre fabricator. The model matches experiments without recourse to any adjustable fitting parameters. (C) 2013 Optical Society of America
