However, there was a significant difference in quantity of SiC and Si3N4 which is accompanying product from the different bituminous coal.

用3种烟煤与SiO2在氮气保护下合成SiC，发现烟煤可以作为碳源合成SiC，但不同烟煤煤种合成产物差别很大。

The mechanical properties of coal filled polymer composites The mechanical properties of coal/PP composites were investigated, and the effects of coal rank, particle size, surface modification of coupling and alkylation were discussed. The results show that the anthracite and bituminous coal all can be used as filler of plastic after pretreatment of part devolatilization and surface modification; The modulus of composites increase with the content of coal filler; The coupling agent is of no effect for reinforcing the coal/PP composites, except that there are new oxygenous function group forming on the surface in the process of pulverizing; The F-C alkylation reinforce coal (under 10μm)/PP composites obviously.

4煤填充高分子复合材料力学性能超细煤粉填充聚丙烯复合材料力学性能的研究结果表明，烟煤和无烟煤经过脱除部分挥发分的预处理后，都可用于与塑料共混制备复合材料；偶联剂改性对低变质程度烟煤/聚丙烯复合材料的力学性能基本不起改善作用，而对于经气流超细粉碎后的小粒径高变质程度烟煤及无烟煤则有一定的增强作用；烷基化改性在煤表面接枝了烷基，使平均粒径小于10μm的煤/聚丙烯复合材料拉伸屈服强度普遍提高，煤填充高分子复合材料可在较高含煤量情况下维持良好的力学性能。

The rank of Fushun coal is mainly subbituminous and high volatile abituminous.

抚顺煤的煤级主要为亚烟煤和高挥发分烟煤A。

Iodine levels increase from lignite through subbituminous coal and bituminous coal to anthracite,it indicates that coal adsorbed excess iodine from the hydrothermal fluids during the process of metamorphism,including geothermal metamorphism and telemagmatic metamorphism.

从褐煤、亚烟煤、烟煤到无烟煤，碘的含量越来越高，表明在变质作用(含深成变质作用和区域岩浆热变质作用)过程中煤吸收了热液流体中的碘。

In Indonesia, with over ten years of experience, Banpu is now the fourth biggest coal producer with production capacity of around 19 million tonnes per annum of export-grade bituminous and sub-bituminous coal for domestic utilities as well as commercial users in Japan, Taiwan, Hong Kong, Philippines, Malaysia, Korea, India, and Europe.

在印尼累积了十多年的经验后，万浦目前是第四大煤炭生产者。每年出口级的烟煤和次烟煤的生产能力大约是1900万吨；可同时满足国内的需求并出口日本、台湾、香港、菲律宾、马来西亚、韩国、印度和欧洲。

In first section, the mass size distribution, physicochemical characteristics and formation mechanism of the SPM from pulverized coal combustion in a drop tube furnace were discussed. Factors that influencing the emission characteristics and elemental partition of the SPM were also investigated, which included the distribution of furnace temperature, coal particle size and oxygen concentration.

本文首先在实验室的沉降炉上对六盘水烟煤、平顶山烟煤和合山烟煤分别进行燃烧实验，通过对燃烧生成的颗粒物收集后进行XRF、SEM、SEM-EDX等分析，研究了颗粒物的质量粒径分布、物理化学特征及亚微米颗粒的形成机理。

Cities have banned the burning of the coal bricks that warmed the kangs and contributed to eye-searing 蛰/迷眼的 smog.

这些城市已禁止市民烧大烟煤，这些烟煤是以往用来为炕供暧，也是产生迷眼烟尘的祸首。

Have produced the natural radioactive level of the colliery of Yunnan through the investigation: Mainly it is brown coal , it is low bituminous coals rotten, in bituminous coal and levels radioactives natural of bituminous coals rottens highs rotten.

通过调查得出了云南煤矿的天然放射性水平：主要是褐煤、低变质烟煤、中变质烟煤和高变质烟煤的天然放射性水平。

The trend of 4 bituminites are between one of brown coal and dry-burning coal, ignition-temperature decreased 15% or so, 60～100℃. And the decreasing velocity of the bituminites' ignition-temperature become lower after the oxygen concentration reach 26%.

四种烟煤的趋势居于贫煤和褐煤之间，着火温度下降15％左右，绝对值下降60～100℃，且烟煤的着火温度在氧气浓度达到26％后，下降的速度降低。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
