In this novel cyclization, nucleophiles very regioselectively attack the internal C1′alkyne carbon of enediynes to give benzene derivatives as a single regioisomer.

在这新的环化，亲核攻击非常regioselectively内部C1'alkyne碳的enediynes给予苯衍生物作为一个单一的regioisomer 。

Diamond, an allotrope of carbon, has many physicochemical properties unrivaled by other known materials, such as superhardness, high thermal conductivity, high spectral transmittance and perfect electrical insulation. Thus it is considered an ideal material for many special applications in mechanics, thermotics, optics, electronics and other fields.

金刚石是碳的一种同素异形体，具有许多其它材料无法比拟的物理化学性质，如超高硬度、高导热率、高光学透过率和极好电绝缘性，因而在力学、热学、光学和电子等领域有许多特殊的应用价值。

Seven years experiment on the effects of bioorganic fertilization, including 15t/hm^2a and 7.5t/hm^2a vermincompost (EM compos, EM chook manure and traditional vermicompoat), and chemical fertilizer on soil fertility and microbial biomass carbon was conducted at the Quzhou Station of China Agricultural University.

为了研究施用生物有机肥（EM堆肥，即有效微生物制剂＋堆肥）对土壤肥力及微生物生物量碳的影响，进行了7年的施用15t/hm^2a有机肥、施用7.5t/hm^2a有机肥（包括EM堆肥、EM鸡粪肥和传统有机肥）、施用化肥和对照处理的田间试验。

The answer is clearly no, because CO2 trading is only bureaucratic air quality control, it is a measure to decarburize the industry, it is a brake to economic growth, it is distortion of free competition and it is absurd with respect to global energy consumption.

答案显然是不。因为二氧化碳贸易只是官僚主义的空气质量控制，是工业脱碳的措施，是经济增长的阻碍，扭曲了自由竞争机制并且这与全球能源消费相关真是太荒谬了。

Deforestation accounts for 20% of all current carbon emissions.

森林砍伐所造成的碳的排放量占世界总量的20%。

The oil-saving agent can be added in fuel oil at low dose with the proportion of 0.005-0.020% and has the functions of combustion supporting, lubrication and carbon deposition removing; road tests show that the oil-saving rate reaches 8%-15%.

该节油剂以较低的剂量0.005-0.020％比例加入燃油中，具有助燃、润滑和清除积碳的作用，行车试验表明节油率达到8％-15％。

The release of the carbon in these compounds for recycling depends almost entirely on the action of both aerobic and anaerobic bacteria and certain types of fungi.

这种化合物通过碳的释放来实现循环，主要依靠喜氧和厌氧细菌以及一些菌类的活动。

We study the electrical property of a-C nanowires by two-terminal measurement. The a-C is found to have poor conductance, while in nanometric-scale thickness, it exhibits small resistance and ohmic conduction.

我们用两端法测量了无定型碳的电学性能，发现其导电性能较差，然而在纳米级的厚度上，电阻很小，其电导呈欧姆特性。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
