新型的光纤材料和制造工艺目前正处于研究和开发之中。现在采用的“普通”制造工艺有:改进的化学气相沉积法、内气相氧化法、外气相氧化法、气相轴向沉积法、等离子化学气相沉积法以及双坩锅法,在改进这些工艺方
New types of fiber materials and manufacturing processes are currently under research and development. The “normal” manufacturing processes now employed include improved CVD methods, internal gas phase oxidation, external gas phase oxidation, vapor phase axial deposition, plasma CVD, and dual crucible methods. In improving these processes
