查询词典 carbons

The direct incorporation of U-13C glucose was estimated by the intensity increase of m/z to F(F was parent fragment, and n was the carbon number in the fragment), while the total isotope incorporation from the added 13C could be calculated according to the abundance ratio increment summation from m/z (Fa+1) through (Fa was the fragment containing all original skeleton carbons, and T was the carbon number in the amino acid molecule). The 13C enrichment in the target compound was expressed as atom percentage excess, and that of D-amino acid needed to be corrected by the coefficient of hydrolysis-induced racemization. The 13C enrichment reflected the carbon turnover velocity of individual amino acid enantiomers, and was powerful to investigate the dynamics of soil amino acids.

外加葡萄糖直接合成氨基酸的比例可利用质谱碎片的相对强度变化来评价（n为质谱碎片F中含有的碳原子数目）；而源于葡萄糖的13C同位素在氨基酸分子中的富集程度是所有同位素峰相对强度变化的总和。13C在目标化合物中的富集比例用原子百分超评价，D氨－基酸的APE还需进一步利用水解诱导的外消旋化系数校正。13C在目标化合物中的富集程度可反映各氨基酸手性异构体的碳循环速率大小，是研究土壤氨基酸动态变化的有力工具。

I knew, these days high strength hiking with a load of backpack in high mountains and reaction to high altitudes resulted in my face and four limbs of edema, looked at my hands, they were exquisite and velvet before we got in xia te,and not they were dark like carbons, and so dry like a bed besom.

后经分析，是由于这几天高强度的高海拔负重、徒步与高原反映而导致面部和四肢浮肿变形，再看双手，来夏特之前虽不能说是肤似柔胰但也可称得上是细腻光滑，现如今已漆黑如碳遍布肉刺干燥的可以用来当床扫。

The method of preparation activated carbons includes two steps: carbonization and activation.

活性炭的制备方法分为炭化和活化两个阶段。

To further reveal the structure of monocotyledon lignin, carbon 13 enrichment of specific carbons of rice stalk lignin was achieved by feeding coniferin [α 13 C], coniferin [β 13 C] and coniferin [γ 13 C] into an internode cavity of the stalk of a growing rice plant Oryza sativa L.

为了进一步了解单子叶植物的木素，向生长中的水稻(OryzasativaL 。)茎秆节间的腔体分别注入在侧链α、β、γ位带13 C标记的松柏醇葡萄糖甙，得到侧链带13 C标记的稻秆木素。

Electronic products and accessories always generate carbons filled around the environment. Carbon is the main embalmer of pollution, a surfeit of carbons will cause a critical destruction of our nature, when we should keep those electronic products in off-mode power when they're not in use. They should've been thoroughly stopped running in order to saving energy.

电能产品和附属品常会制造碳充斥整个环境，碳是主要的污染化学物质，过多的碳会造成我们大自然严重的破坏，我们应该保持那些电器产品，当它不在作用时处於完全停用的状态，为了节省能源，它们该完全被停止运作。

In chapter 5, the thermodynamics of three kinds of PPP-based carbons, namely 650℃、700℃、900℃ PPP-based carbons, are examined with columbic titration method and the partial molar enthalpy and partial entropy as a function of intercalated lithium concentration are calculated.

以650℃PPP碳材料为例，对库仑滴定曲线进行了理论分析，指出当01时嵌入电极的电极电位和锂的嵌入比浓度之间符合Nernst方程。

It indicates that sp3 bonds have been formed between adjacent fullerene molecus via [2+2] cycloaddition reaction, leading to the inequivalent sp2 carbons on C60 cage. The former line has been broadened and has several components due to this inequivalent sp2 carbons.

这表明通过[2+2]加环反应在邻近C60分子之间形成了sp3杂化共价键，使得C60分子球笼上出现了五个位置不等价的sp2杂化碳原子，导致位于145ppm附近的sp2杂化峰展宽。

The carbons in explosives are decomposed into gas-like carbon atoms in the detonation reaction zone, then unoxidized carbon atoms coagulate into carbon liquid droplets and finally consolidate into solid diamonds The new mechanism differs from one conclusion that carbons of explosives are at first transformed into solid graphites, then into diamonds, and also differs from the conclusion that gaseous carbons coagulate into liquid droplets in the reaction zone, then crystalize into diamonds in Taylor rarefaction wave zone.
