From the research of the kerogen carbon isotopes of the coal-measure strata in some basins of China (the Carbo-Permian in the Ordos basin, the Triassic in the Sichuan basin, the Jurassic in the Jungar basin and Turpan-Hami basin, the Tertiary in the Yingqong basin) it can be indicated that the Type Ⅲ kerogen has a wide δ〓C range from -21. 2‰ to -27. 6‰, averaging -25‰, which is more enriched in 〓C than sapropel and mixed kerogens.

对我国一些含煤盆地（陕甘宁石碳－二叠、四川三叠系、准噶尔侏罗系、吐哈侏罗系、莺琼盆地第三系）的煤系地层干酪根碳同位素研究表明，煤系地层的干酪根碳同位素组成δ〓C值分布范围为－21.2～－27.6‰，说明其变化范围较宽，平均值为－25‰左右，相对腐泥型干酪根和混合型干酪根较明显地富重碳同位素。

Therefore, due to the fact that the (111) pole density in the subsurface of decarburized bands still have a higher intensity, adding Mo into Hi-B steels could lower the slab reheating temperature.

本文采用X射线极密度和取向分布函数方法，证明含Mo Hi-B钢采用1310℃低温铸坯加热时，其热轧板表层织构特征与不含Mo并在1380℃高温铸坯加热时相似，为典型的剪切形变织构，两者的热轧板与脱碳板表层织构特征也极为相似，而含Mo Hi-B钢在1380℃铸坯加热时却没有以上这些相似性。

The retorting process of coals using hot char as solid heat carrier lines up every single process which is needed for the production of CMS.

以灵武煤半焦GLW-72为原料，粉碎至粒度＜160目，混入40wt%的亚硫酸盐纸浆废液成型，将成型物在N〓气保护下，以10℃/min的升温速率加热到900℃碳化45min，冷却到室温所得碳化产品用于变压吸附空分，可获得含N〓96.3vol%的富N〓气体；将上述产品进一步作碳沉积处理，可获得空分性能达98.4vol%的炭分子筛，该结果与在同一空分装置上测得的国外炭分子筛的空分性能（98.23vol%）相当。

At present, much attention had been paid to the study of the surfactants with four coordinate boron oxygen heterocycles structure, however, the main work was focused on the synthesis of the surfactants containing boron with short-carbon chain alkyls and their basic properties.

目前研究的方向主要是含四配位硼氧杂环结构的表面活性剂，但都是对一些含短链烷基的合成和基本性质研究，对含长碳链的还极少见文献报道。

Choose sensible carbohydrate-rich foods. Carbs don't have to be gooey and chocolatey every time, Wurtman says. She suggests low-fat crackers, for instance, or pretzels. It keeps the fat low but gives you the carbs you want.

对富含碳水化合物的食品要有所选择，碳水化合物并不总是意味着蜜糖和巧克力食品，Wurtman说，她建议选择低脂饼干如椒盐饼干，它含较低的脂肪并且能够满足你对碳水化合物的需求。

They are classified based on their backbone of carbon atoms: Trioses have three carbon atoms, tetroses four, pentoses five, hexoses six, and heptoses seven.
