For durain particle, no obvious fragmentation is found under the same experimental condition.

结果表明，亮煤与灰煤均发生一次破碎，破碎后生成许多细小颗粒，其中粒径0.8mm以下的细颗粒占多数；暗煤则不发生一次破碎。

Wu renyao: hello,hello, hello. Every villager, for a xing as well as our tomorrow village, i, wu renyao, decide to organize a band with identity of prince of durain to participate Sir Fruit Competition.

吴仁耀：喂喂喂，各位乡民们，为了阿星以及为了我们明日乡，我吴仁耀决定以榴槤王子的身份呢组一个 band 去参加水果先生的选拔大赛。

The pore capacity is becoming smaller with increasingthe vitrinite content. 2. Micro-porosity is dominated in the total pore capacity, which takes more than50%. There is not relationship among pore capacity and specific surface with otherfactors such as Maceral and R0, which shows that the distribution and shapes of poreare not influenced by the composition of the coal. 3. The pore is opened for the coal of Ordos Basin, the order is from durain to clarainthen samples to vitrain. Others are belong to half-opened and thin throat. 4. The adsorption content of gas is increasing with the higher pressure, and the freegas content is decreasing;The adsorption content of gas is decreasing with thehigher temp, and the free gas content is increasing;The adsorption content of gas isincreasing with higher vitrinite content for the kennel coal when temp.

总空隙主要由小孔孔容构成，小孔孔容占了50%以上；镜质组含量和惰性组含量等物质以及镜煤反射率均与孔容、比表面未表现出明显的相关性，说明孔隙分布特征不受物质组成的影响 3、鄂尔多斯地区的空隙呈现开放状态为主，空隙开放的次序为暗煤-亮煤-煤样-镜煤，其他盆地则为半封闭和细瓶颈空隙 4、随压力增加，煤对气体的吸附量增加，煤中所含游离气的量随之减小；随温度增加，煤对气体的吸附量减小，而煤中所含游离气的量随之增加；在相同的温压条件下，同是长焰煤的样品，吸附量在孔容中所占的比例随镜质组含量增加而增加。

Seven coals from Shenfu, Huangling, Huating, Yaojie, Lingwu, Datong and Urumuqi coal districts were selected as samples to study in this project. At first, petrographic characteristics, proximete and ultimate were done upon the coals.Lithotypes as vitrain, fusain, clarain and durain were separated.

本项目选择我国西北地区的神府矿区、黄陵矿区、华亭矿区、窑街矿区、灵武矿区、大通矿区、乌鲁木齐矿区的七种煤，首先进行了煤岩、煤质研究，得出这些煤的惰质组含量普遍较高。
