伸缩环

FT-IR spectrum showed that the new bands at 3000cm-1~2700cm-1 and 1600cm-1~1400cm-1 were assigned to the C-H telescopic vibration and the framework vibration feature of imidazole ring, besides the characteristic bands of BMMs appeared in all samples, however, all of characteristic bands for imidazolium ionic liquid disappeared in the samples when calcined at 550oC, which implied that the structure of imidazolium ionic liquid has been destroyed during calcinations.

FT-IR分析测试中3000cm-1~2700cm-1及1600cm-1~1400cm-1波数范围内的谱带被认为是饱和的C-H伸缩振动和芳环骨架振动，说明离子液体的存在，这些峰只在萃取样品中出现，可见键连的离子液体的结构在焙烧过程中被破坏。

Comfortable and Stretchy Enhancement Ring For Him.

舒服，他伸缩加强环。

By using Lyapunov theory, the σ adjusting law of the contraction and expansion factor is given, and it has been proven that the closed-loop is uniformly ultimately bounded.

基于Lyapunov理论，给出了伸缩因子的σ调整律，并证明了闭环系统一致最终有界。

Computationalresults indicate that the no-planar trans-benzanilide is the most stable structure. The spectra indicate that the Franck Condon region photodissociation dynamics have multidimensional character withnine activemodes. The intensity of υ24 mode in methanol is much stronger than that in acetonitrile. Compared with fatty amides and benzamide, phenyl substitution for H atom on-NH2 group makes C=O solvent effects disappear.

结果表明，苯甲酰苯胺的非平面反式结构为最稳定结构；在Frank-Condon区域内，苯甲酰苯胺主要由9个活性振动模组成；其中ν24（苯环上C＝C不对称伸缩振动和CCH的面内弯曲振动，NH面内弯曲振动）振动模在甲醇溶剂中的强度远远大于其在乙腈的强度；与脂肪酰胺类化合物和苯甲酰胺的研究结果比较发现，苯基取代－NH2上的H原子使得C＝O不再具有明显的溶剂效应。

Lock the support ring onto the diverter housing and release it from the slip joint.

将隔水管张力器支撑环销到转喷器壳体上，从伸缩节上松脱。

Therefore, the previous data of heats of formation of polynitrocubanes estimated from groupadditivity method are corrected.3. Calculations indicate that, for polynitrocubanes, there are parallel relationships between their experimental kinetic acidities pKa, the average s characters in the exocyclic carbon orbital used for the C-H bonds within each molecule, and the average C-H stretching frequencies within each molecule.

计算结果表明，多硝基立方烷的实验动力学酸性pK_a、分子内用于形成C-H键的环外碳轨道平均s成分和分子内的平均C-H伸缩频率之间，存在平行的递变关系，这对基于s_a或v_a的数值预估动力学酸性pK_a、进而指导多硝基立方烷和其它相关化合物的合成有助。
