The result showed that the content of soil carbon indices on slope cropland were lower and increased dramatically in linear pattern after the cropland were abandoned for some time. 50 years after abandonment, OC, AOC and NAOC would increase by 169%, 144% and 210% respectively, compared to the slope cropland and would be 35 %, 39 % and 33 % respectively, of t he natural Chinese arborvitae stand. The carbon pool index and carbon pool management index would sharply increased by 169% and 117%, comapared to the slope cropland would increase by 35% and 42% respectively, compared to natural Chinese arborvitae stand.

结果表明：侵蚀环境的坡耕地土壤碳库各组分含量较低，土壤碳库处于高速低效率运转；撂荒后可以显著增加土壤碳库各组分含量，并随恢复年限呈显著线性关系，50 a时，TOC、LOC和NLOC分别较坡耕地增加169%、144%和201%，为侧柏林的35%、39%和33%；碳库指数和碳库管理指数较坡耕地明显增加，增幅分别达到169%和117%，仅为侧柏林的35%和42%。

Under the same time of restoration, the content of soil carbon and management index of hippiphae rhamnoides are remarkably larger than arborvitae.

相关性分析表明有机碳、活性有机碳、非活性有机碳、碳库指数、碳库管理指数与土壤主要肥力因子相关性极其密切，可以作为反映生态恢复过程土壤质量演变的指标。

If there are five or more bonds to a single carbon atoms, it will be short of electrons and have a positive charge - this species is called a carbonium ion, a form of carbocation.

阳碳：如果有五个甚至更多的键连接在一个碳原子上，碳原子由于缺乏电子而带正电，这种物质称为阳碳，这是碳正离子的一种。

"Carburize:To treat, combine, or impregnate with carbon, as when casehardening steel ."

使渗碳，碳化：使与碳一起处理，使与碳混合或使充满碳，如将钢的表面粹火硬化。

Steel plant, the water model and the method of the circulation flow rate determination of RH vacuum degasser have been established.

RH改进脱碳模型可以预测RH处理过程中的碳含量；利用该模型还得到了最佳初始碳氧含量曲线；为达到最大脱碳速率，应降低转炉出钢含碳量，增大低碳范围内真空室搅拌能；论文还得到了OB与否曲线图，最佳OB时间和最佳OB量。

The effects of C/Fe on desulphur rate is obvious different from the influence on content of sulfur in DRI, the mechanics of desulphur of pellet bearing carbon in DR process depends strongly on the exist constitution of sulfur in it.

含碳球团中的硫酸盐硫将残留在DRI中，文章据此提出了临界内配碳比的概念，当内配碳比低于临界值时，提高内配碳可以同时起到加速还原和脱硫的作用，当内配碳比高于临界值时，将会造成DRI含硫超标。

The results showed that the unsaturated fatty acid content of pecan kernel oil was 89 0%,and 13 kinds of unknown components such as nonadecaol,8 hexyl pentadecane,10 methyl eicosane,11,14 eicosadienoic acid,1 bromo 8 heptadecyne,9 hexyl heptadecane,tetracosane,13 docosenoic acid,1 bromo 7 nonadecyne,15 tetracosenoic acid,hexacosanoic acid,7 hexyl ei...

研究结果表明：山核桃仁油中的不饱和脂肪酸 w =89 0 %，未知成分是十九醇、8 己基十五烷、10 甲基二十烷、11，14 二十碳二烯酸、1溴 8 十七炔、9 己基十七烷、二十四烷、13 二十二碳烯酸、1 溴代 7 十九炔、15 二十四碳烯酸、二十六酸、7 己基二十烷、二十七烷共 13种，其中13 二十二碳烯酸、15 二十四碳烯酸、十九醇等具有较强的生理活性和药用价值

The primary produces are common negative carbon,half graphite negative carbon used for the electrolytical aluminium.

公司主要生产铝电解用普通阴极碳块、半石墨质阴极碳块、30%以上高石墨质阴极碳块、100%全石墨质阴极碳块和各种异型侧部碳块以及各种糊类制品等系列产品。

Studies show that the average ratio of w/w(P2O5)(1.62) of phosphates in submarine guyots is the same as that of w/w(P2O5)（1.621）of carbonate-fluorapatite, but is obviously different from that of w/w(P2O5)（1.318）of fluorine_carbonate, suggesting that the phosphates from northwestern Pacific are species of carbonate_fluorapatite.Three types of microneedle-microcolumnar, microgranular and microcryptocrystalline carbonate_fluorapatite with different abundances have been found.

海山磷酸盐的平均化学成分w/w(P2O5)（1.62）与碳氟磷灰石的w/w(P2O5)（1.621）几乎一致，而与氟磷灰石的w/w(P2O5)（1.318）相差甚远，表明海山磷酸盐为碳氟磷灰石，其形态主要有针状_柱状微晶碳氟磷灰石、粒状微晶碳氟磷灰石及显微隐晶质碳氟磷灰石3种类型，它们在分布丰度上存在差异。

The electron impact mass spectra of the chemical products modified by 2-amino-2-methylpropanol of the fatty acids in sunflower oil were analyzed; the allocation rule for the carbon double bonds in olefinic acids was discussed and the location of the carbon double bonds of the fatty acids in sunflower oil was confirmed.

解析了葵子油脂肪酸2-氨基－2-甲基－丙醇化学修饰产物的EI质谱图，讨论了烯酸中碳碳双键的定位规则，确定了葵子油脂肪酸中碳碳双键的位置鉴定出葵子油6种脂肪酸，不饱和脂肪酸相对含量为89.41%，其中人体必需脂肪酸9，12-十八碳二烯酸含量占65.30%。
