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。

Attaching more importance to the sexual relation between a free adult and a non-beard boy who will participate in municipal management , Hellene has not the same passion for the male-female sexual relation as the modern people do .
人们对婚姻中的性关系以及男女间的性爱关系并没有表现出我们现代人的这种热情,处于理论和道德关注中心的是一个自由的成年男子和一个参与未来城邦管理的还未长胡子的男童之间的性爱关系。

I got out several cords of stumps in plowing, which supplied me with fuel for a long time, and left small circles of virgin mould, easily distinguishable through the summer by the greater luxuriance of the beans there.
锄地时,我挖出了许多树根来,有几"考德",供我燃烧了很久,这就留下了几小圈未耕作过的沃土,当蚕豆在夏天里长得异常茂盛的时候是很容易区别它们的。

It is too early to say, for instance, whether the process, so far tried on polyacrylonitrile carbon fibres, will be equally effective on pitch fibres, though Pickering sees no reason why it should not be. It has been tested on cured and uncured material (about 40% of long-fibre pre-impregnated material comprises uncured manufacturing offcuts) and proved successful on both, but it has not yet been tested against samples of sandwich or bonded structure.
也许目前还言之过早,例如,聚丙烯腈碳纤维的回收过程,是否对沥青纤维同样有效,虽然皮克林称,还找不出不可以的理由;另外,对固化/未固化材料(约40%的未固化长纤维预浸渍材料)的分别实验均证明成功,但尚未对夹芯结构或粘结结构样品进行测试。

Vent were studied in this experiment based on scanner-based image analysis. The results showed that drought and AM inoculation had a large, significant effect on plant development. Biomass, total length, surface area, volume, number of root nodes, average diameter and fractal dimension of root system in Broussonetia papyrifera Vent decreased with the reduction of soil moisture, while they were increased by AM inoculation. Special root length in non-AM plants increased when soil moisture was reducing, but it was decreased by AM inoculation.
结果表明,土壤水分状况和接种菌根真菌对构树幼苗生物量积累产生了显著的影响;构树幼苗根系干重、总长度、表面积、体积、根节数目、根系平均直径和分形维数表现出随着土壤含水量的降低而降低,接种G.mosseae则使得该参数比同等水分条件下显著升高;未接种植株比根长SRL表现为随着土壤含水量的降低而升高,接种G.mosseae则降低了同等水分条件下构树幼苗的比根长;土壤水分和接种G.mosseae同样也对根节平均长度产生了影响。

The results indicate that only tungsten oxide grains are formed without sodium sulfate additions, while tungsten oxide whiskers with 0.20.3 μm in diameter and aspect ratio of 5-50 or tungsten oxide nanowires with 1030 nm in diameter and aspect ratio of 50200 are synthesized by some sodium sulfate additions on conditions at 180 ℃ for 1236 h. The phase composition of tungsten oxide whiskers is hexagonal tungsten trioxide. The whiskers/nanowires grow oriently through 〈200〉,〈002〉,〈202〉and〈100〉.

Pristine Li-Al LDHs are synthesized by hydrothermal process in different reaction conditions by varying the aging time for 1 and 24 hours. Both the Li-Al layered double hydroxides (abbreviated as Li-Al LDH1 and Li-Al LDH24 for aging time 1 hour and 24 hours, respectively) were modified by using sulphanilic acid sodium salt hydrate, modified agent to form modified Li-Al LDH1-SAS and Li-Al LDH24-SAS. The morphology of the pristine layered double hydroxides are investigated by using wide angle X-rays diffraction, scanning electron microscopy and particle size analyzer which indicates that the crystallinity and aspect ratio is increased with increasing the aging time from 1 hour to 24 hours. The particle size of Li-Al LDH24 and Li-Al LDH1 are found to be ~1000 nm and ~250 nm, respectively. Both the pristine and modified LDHs are characterized by XRD, FTIR spectra and thermogravimetric analysis.
本研究目的在於改变长晶时间的长短,合成出同径大小的Li-Al LDHs,再经由改质剂sulphanilic acid sodium salt hydrate将Li-Al LDHs无机层材表面有机官能化制备出改质型Li-Al LDHs-SAS,於是进一步藉由扫描式电子显微镜、射径仪和穿透式电子显微镜等仪器分别观察LDHs改质前和改质后其主层结构型态上的变化;从中可以发现Li-Al LDHs随著长晶时间的增加其径有随之增大的趋势,但经有机化改质后其径会由於改质环境的影响明显低许多,针对此现象本实验将未改质和改质后之Li-Al人工无机层材制备成复材进一步探讨其在热性质和难燃特性上的为表现。

Brachiosaurus:长臂龙
事实上,巨蟒样本是在1987年在印度西面的古吉拉特(Gujarat)被发现,盘缠在有一窝恐龙蛋和一个未孵出的恐龙的巢里. 但在大部分时间,诸如梁龙(diplodocus)与80吨的长臂龙(brachiosaurus)可能是不同的祖先,使其后代不得不保护自己.
