上述两种新硬炼焦煤估价反映的质量均为还原后强度不小于64%，风干灰分不大于9%，风干水分不大于25.5%，认可的优质硬炼焦煤和质量不同的硬炼焦煤按照普氏的规格基准进行正常化处理。

An artificial neural network model is set up to depict relation between the self-ignition duration and sulfur content, ash content,oxygen consumption rate,carbon monoxide as well as carbon dioxide generation rate of coal at different temperature of self heating process.

根据煤的硫分、灰分以及煤自燃过程中的耗氧速率、CO和CO2产生率等随温度变化的序列值与煤自然发火期之间存在的密切对应关系，建立了前向多层人工神经网络模型，用已有的煤自然发火实验数据对网络进行训练，得到了神经元间的联结强度，从而准确地表征这种对应关系。

As the lake basin shoals and silts up, the color of clastic sediment gradually changes from black, black gray, gray and grayish green to purplish grey and red purple, meaning that the subaerial alluvial fan deposit of late stage has replaced the fan-delta deposit and that the coal-forming process ends.

待湖盆逐渐变浅和淤积，碎屑沉积物的颜色由黑、黑灰、灰、灰绿逐渐变为紫灰和紫红，表明晚期陆上冲积扇沉积已经代替了扇三角洲沉积，成煤作用随之结束。

Coal they produced is good quality and be noncaking or slightly caking coal. It possessed low S, P and ash content, but have high calorific value. From beginning in 1987, their coal export into international markets, among which,"JING HONG COAL" be exported to Japan, Malasia, etal.

所产煤炭质量优良，属不粘结和弱粘结煤，具有低硫、低磷、低灰、发热量高的特性，是良好的工业和民用煤，从1987年开始进入国际市场，特产&晶洪煤&远销日本、马来西亚等国家和地区，出口煤获质量免检信誉。

The high sulfur coal from Jiexiu in Shanxi is used in this experiment and the influence of removing pyritic sulfur by adding different pyrites depressors on the process of agglomeration was explored in this study,The experiment result shows that adding pyrites depressors on the process of oil agglomeration can improve the sulfur-removing rate.

油团聚是以脱除煤中灰分为主的团聚技术，脱硫的效率很低，采用山西介休的高硫煤，探索在油团聚过程中加入不同的黄铁矿抑制剂(巯基乙酸、重铬酸钾、高锰酸钾)对脱除煤中黄铁矿硫的影响。结果表明加入黄铁矿抑制剂对脱硫效率有一定程度的影响

However, there is plenty of high ash melting point coal in China which could not be gasified in almost all entrained flow bed gasifier currently, so it's imperative that a new coal gasification technology should be built out urgently.

煤气化技术是解决未来能源、环境和能源安全战略的核心技术之一，而我国煤炭的特点是高灰熔点煤的储量多，现有的气流床气化技术大都无法满足其高效气化的要求，因此亟待研发适合高灰熔点煤的先进煤气化技术。

First, the principle of parameter determination in coal slurries is introduced. It is pointed out that this problem may be solved by the combination of three probes, i.

作者首先介绍了煤浆参数测量的原理，分析了采用三个探头，即密度探头、灰分探头和充气量探头可以在原则上解决这一问题，并指出煤浆系统的关键在于煤浆中气泡含量的测量。

At the same time the carton content of fly ash and slag condition of boiler were almost not influenced by coal water slurry technology applied. These show coal water slurry rebuing technology applied in large scale station boiler is a prospect method and offer instruct for the practical utilization of coal water slurry reburning.

同时试验结果表明采用水煤浆再燃技术时对炉内结渣状况和飞灰含碳量的影响很小，说明大型电站锅炉上采用水煤浆再燃是一种有前景的脱硝方法，这对水煤浆再燃技术的推广应用具有重要意义。

During extracting vacuum still bottom and hydrocyclone underflow of H-coal process,coal liquid could be clearly divided into deashed liquidproducts of ash yield less than 0.05% and ash-rich residue with ash yield greater than 60%.

在萃取氢-煤法减压蒸馏釜液或水力旋风分离器底流物时，这些重质物料可分离成灰分在0.05%以下的低灰液体产品和灰分达60%以上的富灰残渣。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
