Since the result of FFT of FID rarely exhibits the desired pure absorption line, phase correction of FT NMR spectra becomes a necessity in NMR data processing.

由于仪器和实验条件的关系，核磁共振的FID信号经FFT变换后所得的谱线往往不是需要的纯吸收线形，NMR谱的相位校正也就成了NMR数据处理中的一个基本环节。

In the end, the synthesis condition and influential factors of PU-titania (TiO2) process, such as manufacturing sol (including the amount of water, the amount of PU/Titanium butyrate, the concentration of the solution, the pH value, the kind of alcohol), aging process, theoretical analysis of the dipping process, dry and heat treatment of the gelation, were also discussed especially. FT-IR、SEM、TEM、DLS techniques were applied to analyze and study the reaction mechanism and watch the surface and section of the PU-TiO2 membrane. According to above, it was inferred that PU-TiO2 membrane (containing K600) was better composite.

本文采用原位合成法制备了聚氨酯-二氧化钛水分散复合体，并着重对影响制备稳定透明的复合体的因素（包括加水量、醇的加入量、pH值、聚氨酯/钛酸四丁酯投入量、醇种类）进行讨论，利用红外光谱技术分析聚氨酯-二氧化钛分散复合体的结构，动态光散射技术与扫描电镜分别表征复合分散体的粒径大小与分布及复合膜的表面形态，结果显示含K600的聚氨酯-二氧化钛体系复合情况良好。

In this paper, The influence of heat set and dyeing on the structure of PTT fiber was investigated by FT-IR, DSC, critical dissolution time. The influence of heat set on the dyeability of PTT fiber was discussed, too. Meanwhile, many experiments on the dyeing performance of PET fiber were carried out. The effect of different dyeing temperature on the uptake and visual color depth value and dyeing characteristics of different dyes with temperature increasing were discussed, and the influence of temperature on the dyeing depth were also evaluated when dyeing for PTT and PET fiber in the same dye bath condition. Especially the kinetics and thermodynamics of dyeing with disperse dyes were mainly studied.
