查询词典 C.H.

The C, H chemical shifts of the compound were assigned and the coupling constant, J values, were also given out. The three downfield proton and carbon signals in the 1H NMR and 13C NMR spectra for target compounds have been assigned for the first time.

对代表性目标化合物TM-I-5c的NMR谱进行了详细的研究，对其C、H化学位移进行了全归属，给出了相应的偶合常数J值，并确定了其空间结构。

Results The structure was determined by X-ray single diffraction,being a hexagonal system with space group R-3 and a=1.790 7(1)nm,b=1.790 7(1)nm,c=2.816 2(3)nm,α=90°,β=90°,γ...

不同单元的分子由分子间C—H…O氢键和C—H…π弱相互作用连接在一起，形成三维结构。

We suppose that C is a category with involution *, a is a morphism of Category C, h and k are inversive symmetrical morphisms of category C. If there is a morphism x, satisfyingthen x is called a general Moore-Penrose inverse of a on morphism h and k .

设C是具有对合*的范畴，α是范畴C的态射，h，k为范畴C的可逆对称态射，如果存在一个态射x，使得则称x为α的关于h，k的广义Moore-Penrose逆，记为α_~+。

The results showed that the content of Se element in the Se-MT was 2.5 folds higher than that of Zn-MT, on the contrary the content of sulfur element in Se-MT was 2 folds lower then Zn-MT, C, H, N contents in MT were no significant differences in both groups. In terms of chemical property, the element of selenium is very similar to sulfur because they are in the same group in the periodic table. The above results illustrated that the Se could replace S from SH-sulfhydryl to SeH-selenihydryl in cysteine, which presents the existence of a novel Se-MT.

结果表明Se－MT中Se元素含量高于Zn－MTZ.5倍左右，而 S元素含量低于 ZnMT 2倍左右，C、H、N元素含量无明显差异，这说明了麦硒康诱导后Se仙T分子结构上的差异，由于Se元素与S元素同属氧族元素，在化学性质上极为相似，故Se元素极可能替代了MT的合成过程中所必需半味氨酸残基中的SH一基因上的S元素成为SeH一基团，这样我们就得到了一种含SeH一基团的新型Se－MT。

B. Each kind of nucleic acid is composed of three parts: Molecular azotic basic group + member pentose + molecular phosphoric acid radical, DNA is by C, H, O, N, the P five kind of elemental compositions. c. The nucleic acid azotic basic group may divide into four kinds: Guanine, thymine, adenine, cytosine d.

b。 每一种核酸由三个部分所组成：一分子含氮碱基+一分子五碳糖+一分子磷酸根，DNA都是由C、H、O、N、P五种元素组成的。

The nature of another metal-sensitive vibration mode at 1110-1116 cm-1, which was previouslyassigned to the C-H bending,is now re-assigned as an isoindole breathing mod e with some small contribution also from C-H in-plane bending.

另一个对金属大小敏感的振动区在1 110一1 1 16cm一'之间，这一特性己被定义为带有C一H平面弯曲振动的叫噪坏的呼吸振动模式。

Disposal: unproblematic C, H and O

In this chapter,we use the improved inequality in article [9] to proved that under certain conditions,the equation (2.1.2) belongs to L·S∩L·C can be decided by the equation (2.1.1) belonging to L·S∩L·C.H.

本章利用文[9]中推广的不等式，证明了在一定条件下，方程(2.1.2)属于L·S∩L·C的问题可由方程(2.1.1)属于L·S∩L·C来判定。H。

The inconsistency creates special problems with consolidated containers—those that carry cargo from more than one shipper, said David Katz-man, director of regulatory compliance at C.H.

不一致产生特别的联合容器的问题-来自超过一个装货者的进位货物，说大卫 Katz 的那些-男人， C.H。

As to the personal image, not only integrated with the mature elite class who recommends High-Fashion, meanwhile kept the Cool-Style personality, this duality of self-identity and the longing for change is what C.H pursues.

在个人形象上，既需要自然融入那些推崇High-Fashion的成熟精英阶层，又希望保持Cool-Style的自我个性，这种自我认同的双重性和对变化的渴求，正是C.H品牌追求的方向。
