1.The machining accuracy requirement on ceramic interface for fibre optics is up to micron and submicron orders, e.g. coaxality of the cylinder and the bore of interface is 1μm and roundness is 0.5μm.
陶瓷光纤接口要求外圆与内孔的同轴度1μm、圆度5μm，加工精度达微米级和亚微米级。
2.Michel: Definitely not, it is only rumour. We will not give up fibre optics business.
绝对没有，那只是一个谣言。我们不会放弃光器件领域。
3.The uses of this adaptable material have been broadened dramatically by new technologies: glass fibre optics — more than eight million miles — carrying telephone and television signals across nations, glass ceramics serving as the nose cones of missiles and as crowns for teeth; tiny glass beads taking radiation doses inside the body to specific organs, even a new type of glass fashioned of nuclear waste in order to dispose of that unwanted material.
这种适应性强的原料的使用通过新技术显著地被扩大了:玻璃光学纤维-长于八百万英里-承载着电话和电视信号越过国家，玻璃陶瓷制品应用于飞船前端椎体和牙冠；带放射线的小玻璃珠在身体内有特殊的功效，甚至一种新的玻璃类型是核废料式，为了除去不必要的原料。
