Since complex constitutes of raw material, various reactions and phases are involved in the process of mesophase evolution, we suggest that a given carbonaceous mesophase product should be manufactured by selecting raw materials and setting pyrocondensation conditions according to the specific requirement of the product, so that products with the best structure and performance could be obtained.

通过讨论指出，由于炭质中间相涉及的原料种类多样，热缩聚制备过程中涉及的反应、物相复杂，因此，在制备特定性能的产品时，应针对产品的特定性能要求来选择原料、设定热缩聚条件，以制得具有最佳结构和性能的产品。

Sequential leaching experiments indicate fluorine in carbonate rock, phosphorite and Mo-Ni ore layer occurs principally in dissolvable forms: water-soluble, associated with carbonate or phosphorite, so fluorine in which rocks have high chemical mobility at surface conditions. Fluorine in siliceous rock, black shale and carbonaceous slate mainly occurs in undissolvable forms, which are inert at surface conditions.

氟在碳酸盐岩、磷块岩、钼、镍等多元素富集层及部分硅质岩中主要以水溶态、碳酸盐结合态等易溶形式存在，其在自然条件下的化学活动性强；而氟在碳质板岩、黑色页岩及大部分硅质岩中主要存在于难溶矿物中，其化学活动性较弱。

Charring material will product large amount of solid carbonaceous residual, mainly char, after combustion.

炭化材料燃烧后会留下相当数量的残余物，主要是炭，其典型代表是木材。

The carbonaceous lead zinc ore in Inner Mongolia is very large in reserve,but it contains a high level carbon,which interferes with the selective flotation of these ores,making the selective process target very low and economic benefit poor.In recent years,the decarbonizing technology has been greatly improved that provides enough reliable information to exploit these ores

近年来 ，在内蒙古地区先后发现了几处大型含碳铅锌多金属矿床，但矿石中的高含碳量已成为制约铅锌矿开发利用的主要因素，以至于有些矿床至今未被开发利用，除碳已成为含碳铅锌多金属矿床开发利用的关键由于碳对浮选药剂的选择与消耗、工艺流程的制定和技术经济指标都有显著

According to this scheme, the Longmaxi Formation is only referred to as the black siliceous and carbonaceous shales at the base of the Silurian strata. All the carbonate rocks above it have been redelineated and redivided into new lithostratigraphic units.

新方案除对志留系底的黑色硅质碳质页岩沿用龙马溪组这一岩石地层单位名称外，其上的碳酸盐岩均重新划分和建立了新的岩石地层单位，并确定其涵义和时限标准。

The post-earthquake geological study shows that the exposed fault planes accompanying with co-seismic scarps usually occurred along the coal seams and carbonaceous shales.

2008年汶川8.0级地震沿龙门山断裂带内的映秀—北川断裂和灌县—安县断裂分别形成约230 km和70 km的地表破裂带。
