查询词典 carbon process

Scientist: The point is that the worlds soils are a very large reservoir of carbon and two things can happen you can either manage it so they get bigger and therefore lock up carbon, or mismanage it so that pore gets smaller and in fact you release carbon and add to the CO2 in the atmosphere and it works both ways.

科学家：我们要指出的是，地球上的土壤是一个巨大的碳储存库，有两种情况会发生，一方面我们正确的利用它，增加它的容量以达到固碳减排的目的，另一方面我们的错误做法会使土壤中气孔变小，造成碳释放，增加大气中的二氧化碳含量，事实上这两种情况是同时存在的。

After removing the catalyzer by dense muriatic acid, carbon nanotubes are reacted with mix acid (vitriol:nitric acid=3:1 vol./vol.). By comparing the surface image of gained carbon nanotubes under the different condition, the best mix acid oxidation temperature is fixed on 140°C and the reaction time is 30min. The soluble carbon nanotubes were prepared by decorating of octadecylamine on the surface of nanotubes. Three processes of grafting were investigated in this research.

对碳纳米管的热失重、差热分析结果表明，通过在一定温度下空气氧化可去除大部分碳颗粒；而浓盐酸浸泡可去除碳纳米管制备过程中残留的催化剂颗粒；对在不同条件下与硫酸和硝酸配制的混酸反应处理后得到的碳纳米管的表面形貌研究表明最佳混酸氧化条件为140℃氧化30min。

The δ〓S value of pyrite, sphelerite and arsonopyrite is in the range of 4. 0‰ and -4. 2‰ with the highest frequency occurring around zero, indicating a uniformed sulfur source. The large variation and mainly negative values (0.2‰～-11. 3‰) of δ〓S for stibnite could be interpreted by isotope fractionation. The carbon isotopic characteristics exhibit a mixing nature of magmatic carbon and organic carbon.

矿床中的热液成因黄铁矿、闪锌矿和毒砂的δ〓S＝4.0‰—-4.2‰，呈塔式分布，δ〓S集中在0附近，表明其成矿体系具有均—化硫的同位素组成，而辉锑矿的δ〓S变化范围较大(0.2‰—-11.3‰)，除一个样品外均为负值，这是硫同位素分馏作用的结果。

Based on the theory of Welfare Economics and market structure theory this paper analysis the concept of carbon tax and externality of the consumers and producers in the forests carbon sink market, belive that the impact of the market is correcting externality, prove that the forests carbon sink market is oligopsony at presant.

目前森林碳汇市场属于买方寡占市场，政府需要设计合适的碳税政策，对排污企业征收碳税，使企业在缴纳碳税和购买森林碳汇之间选择。

Coniferous forest ; broadleaved forest ; readily oxidizable carbon ; particulate organic carbon ; soil organic carbon density

针叶林；阔叶林；土壤易氧化碳；土壤颗粒有机碳；土壤有机碳密度

Aimed at solving the problem that high content of unburned carbon in fly ash is unfavorable for its comprehensive utilization in large scale, the fundamental principle of flotation for recovery of unburned carbon from fly ash was theoretically analyzed and the full flotation flow for the recovery of unburned carbon from fly ash was tested.

针对粉煤灰中未燃炭含量过高不利于大规模综合利用的问题，从理论上分析了浮选回收粉煤灰中未燃炭的基本原理，采用全浮选流程对粉煤灰中未燃炭进行了浮选回收试验，探讨了影响粉煤灰中未燃炭浮选效果的主要因素，确定了适宜的工艺条件。

It has high friction properties, resemble anti-wear properties and brake moment curve compared with Dunlop company and Messier-Bugatti company carbon brake discs materials. It has excellent mechanics performance and axis heat conduct coefficients compared with abroad carbon brake discs materials. The friction properties of RTO Wetness normal brake increased by 23％-29% than Dunlop carbon brake discs materials.

与英国Dunlop公司、法国Messier-Bugatti公司生产的炭刹车盘材料相比，其高摩擦特性及抗磨损性能相当，刹车力矩曲线形态相似，且力学性能、轴向导热系数明显高于国外炭刹车盘材料，RTO刹车湿态刹车时的摩擦特性高出Dunlop炭刹车盘材料23％-29%。

It could use Vat Blue RSN as a nitrogen source, but not as a carbon source. The medium composing of saccharose and ammonium nitrate as carbon and nitrogen sources was decolorizing potential markedly during different combinations of carbon and nitrogen sources.

此外， 菌株Asaw117能利用还原蓝RSN作为氮源，但不能利用其为碳源；几种碳氮源组合实验中，菌株在蔗糖、硝酸铵组合的査氏培养基脱色效果为好。

Generically, forest restore is thought would sequestrate more atmosphere carbon, but carbon sequestration through aboveground biomass increasing may be offset by soil organic carbon loss.

一般认为，恢复森林可以增加碳汇，但在较为湿润的地区，灌木、树木入侵引起的地上生物量增加将被土壤有机碳的流失所抵消。

On 100t BOF-130t LF of Handan NO.3 steel works,with LF refining technology alone,for heavy desulfurization mission and long refining cyclic,the phenomenon of increasing silicium and carbon is much serious on refining low carbon steel specially the cold-rolling low carbon steel.The results impact the products'final performance and percent of pass.

单独采用LF精炼工艺，脱硫任务重，精炼周期长，冶炼低碳钢，特别是冶炼冷轧低碳钢时，LF炉在脱硫的同时，增硅增碳的现象较严重，影响了产品的最终性能和合格率。

Article 144 The Government of the Hong Kong Special Administrative Region shall maintain the policy previously practised in Hong Kong in respect of subventions for non-governmental organizations in fields such as education, medicine and health, culture, art, recreation, sports, social welfare and social

第一百四十四条香港特别行政区政府保持原在香港实行的对教育、医疗卫生、文化、艺术、康乐、体育、社会福利、社会工作等方面的民间团体机构的资助政策。原在香港各资助机构任职的人员均可根据原有制度继续受聘。

Small wonder, then, that the Chinese spend more in the shop than any other group of foreign visitors do .
