In this thesis, theoretical and experimental studies on spectral broadening byusing hollow fiber filled with noble gas are described.

本文对利用充惰性气体的中空光纤进行光谱展宽进行了理论和实验研究。

The spectral broadening is the key. At present, the spectral broadening by usinghollow fiber filled with noble gas is most feasible.

而光谱的展宽更是其中的关键步骤，目前利用冲惰性气体的中空光纤来进行光谱展宽，是最可行的方法。

The system at higher temperature becomes thermodynamically more stable, and raises the diffusion exchange rate of solvent and nonsolvent at the interface according to the diffusion kinetics. For the PANCMA/DMSO/ system, with the addition of DMSO to nonsolvent, the cloud point curves shifts to the polymer-nonsolvent axis, and the homogeneous phase region is broadened, system becomes thermodynamically more stable and needs more nonsolvent mixture to induce liquid-liquid phase separation.

通过浊点滴定，结合LCP半经验关系，可以得到制膜体系PANCMA/溶剂/非溶剂的三元相图浊点线，考察其相分离过程中的热力学性质，同时考察了溶剂和非溶剂双向扩散传质动力学，从体系热力学和动力学性质出发为PANCMA中空纤维膜的制备以及解释最终的膜结构和性能提供理论依据。
