But, fusain is high in density and in HGI. It is usually concentrated in the coals of heavier and finer parts. Less oxygen functional groups exists in vitrain even if the total oxygen is high. However, more oxygen functional groups is found in fusain though total oxygen is low.

指出26uuu亚洲欧美日韩在线，鏡煤的密度較低www.肏屄、HGI值較小、易富集于密度較氫的粗粒徑煤中午夜性交影视，盡管其總氧含量較高鸥美作爱视频、但是含氧官能團(tuán)的數(shù)量相對(duì)較低，絲炭的密度較大黑人国产在线、HGI值較高一本色道久久综合网加勒比、易富集于較重的細(xì)粒徑煤中，其總氧含量盡管較低、但是含氧官能團(tuán)的數(shù)量較高柚木在线无码视频精品。

The results show that the Lande factors are 2.002~2.003, which have little change, and that of coal from Zhangji coal mine are little larger than that form Baijigou coal mine. Small particle size, high oxidation temperature and long oxidation time can lead to high corventration and high line height. However, the trend of line width is dispersive.

結(jié)果表明：煤自由基因子在2.002~2.003之間成熟老熟妇高潮XXXXX，變化不大，張集礦肥煤的因子值稍大于白芨溝無煙煤精品人人；煤體粒徑越小色一区二区三区、氧化溫度越高、氧化時(shí)間越長欧美黑人做嫒在线视频，煤自由基濃度越大国产A片一级黄色；線高的變化趨勢與自由基濃度變化趨勢基本一致；線寬的變化趨勢呈分散性欧美日本男女性爱视频。

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.

Numerous types of activated carbon are available, including pelletized, granular, powdered, impregnated, virgin and reactivated, made out of several different materials such as coal, coconut shell and wood.
