This showed that the electron density of a quinoid ring increased. The peaks of the quaternary carbon atoms of the benzene rings, which were adjacent to the quinoid ring, also shifted to higher field. But the peaks of other C atoms shifted to lower field.

NMR结果表明苯胺低聚体掺杂后主链上的电荷重新分布，环上的H原子上的电子被C原子吸引，电荷密度降低，在〓 NMR中谱峰向低场移动。C原子的谱峰也相应发生变化，醌环上电荷密度增加，全部C原子的峰向高场移动，与醌环相邻苯环受其影响季碳峰移向高场，非季碳峰移向低场。

He scored one quintet for two viola s and the other for two cellos.

Some methods to arise the calculating efficiency for multi-dimensional random earthquake vector processes were proposed. To one dimensional process, the influences of all models to simulated target PSD and mean response spectrum were studied. The importance of frequency properties to models was demonstrated.

还对一维随机过程的平稳与非平稳情形，研究了频率特性对拟合目标功率谱的影响和对单自由度振子反应谱的影响，由此证明了频率特性在拟合模型中的重要性。

Objective To analyze the components of organic acids in the Radix Ranunculi Ternati from different methods. Methods With using 10%H2SO4-CH3OH as methyl esterification solvent, the analysis for organic acids were carried by using GC-MS . Results 46 components were determined.
