内酰胺

In this dissertation, systematic and extensive conformational search has been performed for asparagine and aspartic acid in gas phase and solution and the properties of the stable conformers are studied using DFT based first-principles calculation. The concerned properties include geometry structure, IR spectra, conformer distributions, intramolecular interactions, ionization energies and electron affinities, protonation and deprotonation processes.

在本论文中，我们对天冬酰胺和天冬氨酸在气相和溶液中的稳定构型进行了系统而全面的寻找，并研究了其稳定构型的几何结构、红外光谱、构型分布、分子内相互作用、电离能、电子亲合能、质子化和去质子化过程等相关性质。

The calculated IC times of chl-a in ethyl acetate, tetrahydrofuran and dimethyl formamide are 141, 147, and 241 fs, respectively.

计算得到的叶绿素a分子在乙酸乙酯、四氢呋喃和二甲基甲酰胺溶剂中的内转换时间分别是141、147和241 fs。

2 STR-PCR We analysed the results of STR with the silver dye in the beginning. The silver dye of STR analysis on a sporadic DMD family shows the band confirmation is subjective by eyeballing. It can not detect the small repeats and the size of polymorphic fragments. For limitation of the silver dye, we analysed the band size of STR with the SAGAGT Genotyping System. Primer are designed according to the nucleotide sequence of five STR markers (located in 5' terminus and intron 44, 45, 49, 50) of dystrophin gene. The 5' end of the forward primer are attached a M13 tailed primer which conjugated to the infrared flourescent dye.

根据dystrophin基因5个多态位点（44、45、49和50号内含子以及5'端启动子区的序列）设计引物，在这些STR的上游引物5'端加一可被红外线荧光物质IRDye700识别标记的M13fw的尾：CAC GACGTT GTA AAA CGA C 通过PCR扩增出重复序列本身，经高分辨率的变性聚丙烯酰胺凝胶电泳后，利用红外激光遗传分析系统及SAGA〓基因分型软件对凝胶上的扩增产物及内标的位置，进行扫描分析，确定产物片段的大小。

However, glyceryl linoleate and propionamide in the experimental concentrations had less inhibition on A. tamarense.
