Inkjet cards and membership cards produced by the history can be traced back to 1884, Americans C h. levy, and Richard in the syringe into water, squeeze needle-side flying out of macropaticles, was inspired by this, to make this fly-out liquid electriferous, control their impact point, you can form a portrait on the paper, this is referred to as fog ink business card printing and membership card.

喷不朱制卡和会员卡制作的汗青可以追溯到1884年，美国人C·H·Richard在注射器洋拔出火，挤压针端飞出液滴，由此受到带动，若使此飞出固体带电，用电把持其落点，不离可以在纸上变不败画像，此称为雾不朱制卡和会员卡制作。

Reaction of the ligand with CdI2 or Cu(NO3)2 afforded dinuclear monohelical complexes 1 and 2 equipped with the aromatic rings, and the complex interacted each other through cooperative C-H...π and π...π interactions to form homochiral 2D layer along ab plane.

配体与CdI2和Cu(NO3)2反应得到双核单螺旋化合物1和2，在化合物2中，由于C-H…π和π…π的协同相互作用沿ab面形成单一手性的二维平面。

For both series of heteroleptic tris rare earth compounds, the characteristic phthalocyanine dianion IR bands for Pc2- and O OPc2- at ca. 1329 and 1380 cm-1 attributed to the pyrrole stretching and the symmetric C-H bending of -CH3 groups in octyloxy side chains of OOPc rings together with some small contribution from the isoindole stretching vibrations,re specteively,are simultaneously found in their IR spectra.

在这两个不对称三明治型稀土配合物系列的红外光谱中发现了这样一种特性，即酞菁阴离子Pc~(2-)和OOPc~(2-)的特征波段在1329cm~(-1)和1380cm~(-1)之间，这是因为吡咯的伸缩振动和OOPc环中八烷氧基侧链上-CH_3基团的对称C-H的弯曲振动共同作用于吲哚环的伸缩振动。

With the standards established above and calculated results of gas chemistry of 25 nitrogencontaining gas mixtures at 3000K and 4000Pa, the C-H-N phase diagram for diamond growth was constructed kinetically for the first time, which was proved logical by many experiments in literature.

根据以上建立的标准和25种含氮混合物的气相化学计算结果，首次从动力学角度构建了C-H-N三元体系生长金刚石的相图，并为文献中的大量实验证实是基本合理的。

The majority of nonaromatic compounds do not have such high C∶H ratios.

大部分非芳香族化合物的C∶H比例没有这样高。

The oxidation of saturated C-H bond is an important technical method to obtain oxygenous organic compounds.

饱和C-H键的氧化是合成有机含氧化合物的重要方法。

Covering the chemistry of liquid-phase oxidation of organic compounds, this book includes the results of analysis with the parabolic model as applied to reactions of peroxyl radicals with C-H bond of different organic compounds.

在有机化学和生物学方面的氧化和抗氧化剂有機化学と生物学の面でのアンチオキダントと酸化します包括有机化合物的液相氧化的化学，这本书象适用于peroxyl 激进主义者与不同的有机化合物的C-H 契约的反应的那样用抛物线的模型包括分析的结果。

The arylation showed high regioselectivity and only occurred on the less sterically hinderd ortho-C—H bond. The reaction could be compatible to diverse functional groups such as CH3, CH3O, and CH3CO, as well as Br and Cl substituents, which would permit to be functionalized further to construct new compounds with more complicated structures.

实验结果表明，反应表现出明显的区域选择性，芳基化只发生在空间位阻较小的sp2 C—H键上，反应可以采用多种取代基(如CH3O， CH3CO， Br和Cl)进行，这有助于通过进一步反应构建更为复杂的新化合物。
