8 Mol/L. The electrode process and reaction mechanism of ACOP were investigated. The results show that the proton numbers is 2 and electron transfer number n is 2. The method has been used to determine the content of ACOP in tablets with the recovery between 98.2%~105.0% by means of standard addition method. Compare with ultraviolet spectrometry, the method is not remarkable difference.

The microstructures of composite membranes were studied by XRD and SEM. The thermal stabilities, methanol permeabilities and proton conductivities were investigated. Water uptakes and dimensional stabilities were also studied. The results indicate that amorphous zirconium phosphates are formed in the composite membrane, and have a good combination with the organic phase.

Furthermore, proton singlets of Fmoc group were treated as internal standard because of their station in both starting material and product.

用HR／MAS NMR分析技术不仅跟踪优化了固相羟基氨基酸的糖基化反应条件，而且选择固载在树脂上的糖基化Nα-Fmoc保护羟基氨基酸〓H NMR中最低场，且分辨好的Fmoc保护基信号做为内标，糖上乙酰基的积分面积为标准直接定量了键合在Tenta Gel S NH〓树脂上氨基酸甙化的产率。

The finding of the blue-shifted F-He-H... Y (Y=N〓, CO and He) systems, where the proton-donor was incapable of rehybridization, indicated that rehybridization is not a generally application driving force for the blue shift. There were other two novel blue-shifted systems discovered in this study. They were lithium bonding systems and dihydrogen bonding systems. On the basis of state-of-art NBO analyses and potential energy surface analysis, it was demonstrated that Pauli/nuclei repulsions cause the blue shift.
