The thermoelectric effect of CNT films has also been studied in this research. The study shows that the thermoelectric force is proportional to temperature difference. The Seebeck coefficience is -15μv/K~-60μv/K, which exhibits that CNT films are n-type.

另外，对碳纳米管膜的温差电效应进行了研究，发现其温差电动势与温差成正比，碳纳米管膜的塞贝克系数在-15μv/K~-60μv/K 之间，碳纳米管膜呈n 型半导体性质。

首先将碳纳米管粘附在导电的胶带上，然后用涂胶的针尖与其接触将碳纳米管粘附到针尖上，最后运用电蚀的方法优化碳纳米管针尖的长度，以达到高分辨率的要求。

We measured R with a LI-6400 infrared gas analyzer, and partitioned autotrophic and heterotrophic respiration in the R using a trenched plot approach.

土壤碳是高纬度地区森林生态系统最大的碳库，是森林生态系统碳循环的极其重要组分。

The Tuckahoe fluid ferment conditions including Carbon source, Nitrogen source, pH and culture time were examined .

对茯苓液体发酵的碳源、氮源，pH值及发酵时间等进行研究，结果表明，最佳碳源是葡萄糖与蔗糖，氮源为麸皮，碳源浓度为8%，pH为5.0，发酵时间为5d。

Nanosized WC powders with high carbon content were treated in flowing H_2 atmosphere to remove the uncombined carbon.The effect of processing temperature,holding time,and flux of H_2 on carbon content and particle size of decarburized powders were investigated.

将高碳含量的纳米WC粉末在氢气流中进行热处理脱除游离碳，研究处理温度、保温时间和H2流量等工艺参数对WC粉碳含量及粒度的影响。

An anion in which carbon carries a negative charge and an unshared pair of electrons.

负碳离子，阴碳离子一种阴离子，其中碳带一个负电荷和一个非共用电子对

DOC and HDOC in ridge, rice and rape use pattern in 0~30cm depth layer much more than other treatments after 14 years and showed significant differences;land use of rotation of waterlog rice and dry rape which was disadvantageous to increase the quantity of DOC, which indicated DOC is good evaluation index of soil quality land use effect for paddy soil.

土壤有机质损失的重要途径主要是DOC的淋失，土壤可溶性有机碳是土壤有机碳周转的必要环节，是其中的不稳定组分，主要包括有机残体的可溶性有机物、土壤微生物分解有机残体后未吸收的可溶性有机物及微生物细胞衰老自溶后释放的可溶性有机物[4]，在陆地生态系统碳循环中起着重要作用[5]，所以DOC的分析

From the UV spectra, it can be found that the aromaticity of acenaphthenyl groups in C_2 gum is the largest. But there are 30 carbon atoms in the conjugated structure of condensed aromatics in C_1 gum and C_3 gum, while 28 carbon atoms in acenaphthenyl groups in C_2 gum.

但是，在C_1胶、C_2胶和C_3胶三者中，C_1胶侧链上的四苯基苯基和C_3胶侧链上的菲式多苯基苯基都含有30个碳原子，而C_2胶侧链上的苊式多苯基苯基含有28个碳原子，比前面二者小2个碳原子，理应其芳香性在三者之中最小，但事实却恰恰相反。

Organozinc reagents can react with a variety of α,β-acetylenic ketones and aldehydes in the absence of any catalyst. The one-pot reaction affords β-branched Baylis-Hillman type adducts, the multifunctionalized alkenes, in excellent yields with high stereoselectivity.

这种顺式亲核加成反应的发生是由于该类有机锌试剂既具有较强的亲核性，又具有Lewis酸的特性，使有机锌中R基团从同位进攻中心碳原子而形成新的碳碳键。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。
