Till now, the most used method for storage of hydrogen in array of SWNT's is by physisorption inside the SWNT's and on the outer surface of the SWNT's or in the interstice between SWNT's.

到目前为止，在单壁碳纳米管阵列中贮存氢的最常用的方法是通过虹吸作用或电化学作用使氢物理吸附在单壁碳纳米管的内部、外表面上或者单壁碳纳米管之间的间隙中。

According to these results, it is considered that in the matrix of gray cast iron nitrogen solid-solubilizes as interstitial atom in the octahedron interstice of ferrite and cementite which is not occupied by carbon atom, and causes the crystal lattice of ferrite and cementite to distort, so that the micro-hardness of the matrix increases.

依据这一实验结果，作者认为，在灰铸铁基体组织中，氮以间隙原子的方式固溶在铁素体和渗碳体中未被碳原子占据的八面体间隙里，造成铁素体和渗碳体晶格畸变，从而提高了基体组织的显微硬度。

Gas identity and concentration can be determined by monitoring the ionization voltage and discharge current of the gas. Gas ionization voltages of SWNTs were lower 30 voltages than MWNTs obtained by CVD, and after plasma treatment, the gas ionization characteristics of MWNTs were improved.

与化学气相沉积方法得到的直立式多壁碳纳米管相比较，旋涂法单壁碳纳米管薄膜电极的气体电离阈值电压要低30V左右，等离子处理对改善直立式多壁碳纳米管的气体放电性能有帮助。

The results showed that under the ironstone slurry, the wear loss of the low carbon high alloy steel in different impact energy was lower than the high manganese steel and the medium carbon alloy steel.

结果表明在铁矿石浆料中，在不同的冲击功下，低碳高合金钢的磨损失重比高锰钢和中碳合金钢都要低，而且随着时间的延长，低碳高合金钢的优越性更好地体现了出来。

With increasing altitude, the distribution characteristics of the topsoil (0-20cm) labile organic carbon and organic carbon lability were decrease→increase within the altitude range of

对贡嘎南山-拉轨岗日山南坡高寒草原生态系统表层（0~20cm）土壤活性有机碳分布特征研究表明：表层（0~20 cm）土壤活性有机碳平均为(2.4986±0.7864) g/kg，占表层土壤有机碳的(12.7926±21.00)%。

In this study, alkylhydroquinone, 10'-heptadecenylhydroquinone [HQ17(1)], isolated from the sap of the lacquer tree Rhus succedanea, was found to inhibit the activity of tyrosinase and to suppress melanin production in animal cells.

在之前的研究中，我们已经由漆树Rhus succedanea的漆液中萃取纯化得到的一个对苯二酚衍生物，此衍生物在第二个碳的位置有17个碳的不饱和碳链，根据其化学结构命名为10′–heptadecenylhydroquinone，并简称为HQ17(1)。

The " lead " of a pencil is made of carbon , coal is made of carbon , and so are diamonds .

铅笔中的"铅芯"是碳组成的，煤是碳组成的，钻石也是由碳组成的。

In this paper, morphology transformation laws by plasma modification on cemented carbide (YG16) surface have been studied and influence of decobalt time, decarbonization temperature, decarbonization time and carburizing time main factors on plasma modification lias been investigated.

本文重点研究了YG16硬质合金表面经等离子体改性处理后的组织转变规律，重点探讨了硬质合金表面脱钴时间、脱碳温度、脱碳时间、渗碳时间等主要因素对等离子体改性效果的影响。

Marine δ13C may have varied in the Neoproterozoic, but this could only be deduced following careful consideration of large isotopic changes that occur during lithification and later alteration.

大量的进行光合作用的生物曾经广泛出现并且制造了足够的光合作用碳，这些碳同位素后来进入了海岸地下水并且沉积形成了具有独特碳同位素特征的海相碳酸盐。

Compared carbon pools and turnovertime under different soil types, the result shows: soil total organic carbon is grey cinnamonforest soil＞dark-brown soil＞meadow soil＞brown coniferous forest soil＞red soil＞yellowsoil＞yellow brown soil＞paddy soil＞red soil＞flubo-aquic soil＞fengsha soil,temperate forest soil＞subtropical forest soil＞subtropical cropland soil＞temperate dry soil.Active carbon is temperate forest soil＞subtropical soil.

对不同土壤类型的碳库及其驻留时间进行比较，得出：有机碳含量呈现：灰褐土＞暗棕壤＞草甸土＞棕色针叶林土＞红壤＞黄壤＞黄棕壤＞水稻土＞农田红壤＞潮土＞风沙土，温带森林土壤＞亚热带森林土壤＞亚热带农田土壤＞温带干旱土壤；活性碳含量是温带森林土壤＞亚热带的土壤。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
