摘要：
We consider the drawing of slender optical fibres containing an axial hole, which is initially circular and is not necessarily coaxial with the fibre. A Newtonian creeping flow analysis is used to show that changes in hole shape from circular occur when the hole is not on the fibre axis, but these changes only appear in proportion to the square of the slenderness ratio of the fibre. The final oval shape predicted compares qualitatively with experiments on polymethyl-methacrylate fibres.
