查询词典 coalification

Cleats are the endogenetic fracture systems which are widely distributed in the coal bed and are of great sig nificance for the coal-bed gas to be produced, being the natural fractures formed by desiccation, coalification, lithification and tectonic force.

割理是广泛存在于煤层中对煤层气的产出具有重要意义的内生裂隙系统，是煤层经过干缩作用、煤化作用、岩化作用和构造压力等各种过程形成的天然裂隙。

Research on Coal-forming Environment and Sequence Stratigraphy in Coal Measures Strata;2. The results show:1, there were the differences between the characteristics of the coalification between the Taiyuan Formation vitrain and the Shanxi Formation vitrain which were formed in differencial coal-forming environment s, and the differ.

结果表明：在高煤级煤早期阶段，形成于不同成煤环境的太原组煤与山西组煤的煤化特征仍有差异，在第三次煤化作用跃变之后这种差异逐渐缩小消失；高煤级煤分别以第三次和第四次煤化作用跃变为界，呈现出阶段性演化的特征，每阶段的演化机理有所不同；第三次煤化作用跃变中大分子结构的演化以芳构化作用主为，第四次煤化作用跃变则以强烈的环缩合作用占优势。

Nationwide sampling program is designed according to the resources distribution and coal-forming periods as well as coal rank and yield of coal in China, 305 coal samples were collected and determined by catalytic spectrophotometry combined with pyrohydrolysis.The geochemical mechanism of the concentration or depletion of iodine was discussed during the process of coalification,which including peat diagenesis and coal metamorphism.The contents of iodine in Chinese coals fall in the range of 0.04-39.51 mg/kg.

根据中国煤炭资源分布和成煤时代，兼顾煤的变质程度和煤炭产量分布，在全国范围内采集了305个煤样，采用高温热水解—催化分光光度法分析了煤中碘的含量，探讨了煤化作用(包括泥炭成岩作用和煤变质作用)过程中煤中碘富集或亏损的地球化学机制。
