In the course of coalification, series of macerals are evolved correspondingly.

随着煤化作用的进行，相应地形成煤岩组分演化的连续系列。

Therefore, understanding the change of physicochemical structure is the key to deeply knowing the mechanism and process during coalification.

13C-NMR核磁共振技术是一种无破损的结构分析方法，可从定性及定量的角度对煤结构特征进行分析，已被广泛的应用在煤结构的研究中。

It is shown that vitrainization and fussinization are two processes occurring in coalification, which deviates from the traditional conception.

文中指出，镜煤化作用和丝炭化作用是在煤化作用阶段，基本上同时进行的两个过程。它们区别于传统概念。

The whole history of coalification...

整个聚煤历史表明由于地壳运动不均一、沉降幅度不同等因素影响了沉积环境，从而使聚煤作用发生空间方面迁移的现象，而气候影响则为次要的因素。

The characterof gas emission and the degree of coalification are relative to the breakdown strength ofcoal-bed.

淮北宿东矿区和淮南谢二矿的某些煤层受到过强烈的后生构造破坏，煤体的破碎强度与矿井瓦斯及煤的煤化程度的加深存在正相互关系。

This thesis followed the construction of excitation mechanism, and take rules of general principles and reality of Ningxia Qinghua Coalification Company to analyze specific issues, and to design the material excitation mechanism and non-material excitation mechanism for the company.

本文遵循激励机制构建的一般原理与规则，并结合宁夏庆华煤化公司的实际，具体问题具体分析，分别对宁夏庆华煤化公司的物质和非物质激励机制的进行设计。

So the first method is the best one, which makes use of the temperature discrepancy between brick and flue gas during initial stage of combustion to intensify burning by excess coefficient of maximum coal gas against minimum air, so that the temperature at top of arch can reach the highest specified value 1350℃ in 15-30mins.

因此较优的燃烧制度是固定煤气量调节空气的快速烧炉法，即燃烧初期利用砖温与烟气温度相差较大的时机，以最大煤气量和最小空气过剩系数来强化燃烧，尽快在15～30min内将拱顶温度烧到规定的最高值1350℃。

The TG-DTG-DTA thermal analysis technology is applied to study the combustibility of slime from Xinji coal preparation plant.

采用TG-DTG-DTA热分析联用技术研究了新集选煤二厂煤泥浆的燃烧特性。

The research shows that gas concentration shows generally an increasing tendency along the working face airflow direction, from 0.095% to 0.18%, under the effect of gas drainage points, up-and-down changing locally; gas distribution in a transect of working face is unequal, under the effect of gas emission, ventilation and drainage, the gas concentration near coal wall is larger than that near goaf, which is a concave function distribution within a distance of 1876.5 m from the inlet of working face, after greater than 76.5m, which is a decreasing distribution from coal wall to goaf.

研究表明，该工作面瓦斯体积分数沿风流方向总体呈逐渐增加趋势，介于0.095%~0.18%之间，受瓦斯抽放点的影响，局部有起伏变化；工作面横断面瓦斯体积分数分布不均匀，受瓦斯涌出、通风和抽放的影响，靠近煤壁侧瓦斯体积分数要高于采空区侧，在距离进风口约18~76.5 m范围内为凹函数分布，大于76.5 m之后，从煤壁至采空区为单调下降函数分布。

This designed proposal can realize continuous and uniform coal distribution into coal box of the charging car, it is characterized by less capital construction investment, less difficulties for construction and east for maintenance.

该设计方案可对装煤车的煤箱实现连续均匀布煤，具有基建投资少、建设难度小、维护方便等特点。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
