FTIR analysis was performed on the thermally aged inhibitors to check for any change in molecular symmetry that would indicate thermal degradation.Where crystallisation had occurred,there were obvious differences in spectra with key active inhibitor component peaks.

红外光谱分析等进行了热老化抑制剂检查任何改变，将分子对称的热降解那里发生了crystallisation有明显的差异，在光谱峰与关键部件。

On the bases of heating up amethyst, smoky quartz and yellow quartz; observing the change of their color; determining their absorbency and drawing the absorbency curve in different temperature and on the bases of the results of atomic absorption spectrometry, we discussed the stability of the color centers in quartz crystal.

通过在不同的温度下加热水晶，观察加热后的颜色变化，测定不同温度下的吸光度。根据各色水晶吸光度曲线特征及其在不同温度下的吸光度变化，结合原子吸收光谱分析，探讨有色水晶中空穴心的类型和稳定性。

The different part of corn seed was examined by Raman and IR spectra.

采用傅立叶红外光谱法及拉曼光谱分析了玉米种子不同部位的成分。

The primary amine of DETA is closed by ethyl methyl ketone to reduce the reactivity of –NCO group and –NH2 group and smooth the reaction process. The mole ratio value of –NH2/-NCO should be 2.2 to make sure that –NCO group is completely closed in by –NH2 group and amine terminate compound is prepared. The reaction temperature, reaction time and the way of adding raw materials to vessel are discussed. Structure and performance of the resin are analyzed with infrared ray spectrum.

SF and collagen films were treated by negative corona discharge, homothermal surface potential decay was tested to detect the charge stability. Result showed circums- tance humidity influenced severely the surface charge stability. There were polar groups on the surface after corona discharge, and hydrogen bonds existed between these groups. On the other hand, ATR-FTIR analysis indicated the conformation transition of SF was induced by strong electric field and a part of random coil conformation was converted into β-sheet structure.

采用自制的负电晕极化装置对丝素、胶原膜进行了表面处理，等温表面电位衰减法测试材料在不同环境中表面电位的变化，发现环境湿度对材料表面电荷稳定性的影响较大；XPS光谱分析表明材料表面有极性基团产生，这些基团之间有可能会形成氢键，同时ATR-FTIR分析表明丝素的构象在强电场的作用下发生了变化，由无规线团转变为β折叠结构。

These breakdowns can also be discerned visually in the form of hazing or recrystallisation,but the FTIR analysis gives a definitive representation of changes to the form of the inhibitor molecules contained within the various packages.

这些障碍也可以洞悉刻骨铭心的视觉的形式，但还是再给一个明确的表示傅里叶变换红外光谱分析的形式的乙酰胆碱酯酶抑制剂分子中包含的各种包装。

The recombinant pThr-2 was expressed as intracellular insoluble inclusion bodies and must be refolded for the activity assay.
