CaSO4·2H2O /Ca_2 ratio、hydration temperature、hydration time、fly ash/Ca_2 ratio、fly ash species and skived or not, they were the six most significant factors effect on the specific surface area of absorbent.

石膏/Ca_2质量比、水合温度、水合时间、飞灰/Ca_2质量比、飞灰的种类以及研磨与否这六个制备因素对吸收剂的比表面积有着显著的影响。

Taimyrensis has a mid-grey to greyish-slate mantle, and is usually clearly distinctly darker above than either Mongolian or Vega Gull. Both the neck and wings are longer and slenderer than in the other two species and the head rather smaller.

taimyrensis，上背羽色中灰至偏灰的深蓝灰色，明显的比前述两种灰色深暗，颈部及翼部均较其他两种长而纤细，头部看起来较小。

Equivalent gray absorption coefficient in non-gray system is calculated by inverse analysis, which combines the zonal method and the method of minimization of a performance function stylizing the conjugated gradient.

本文将区域法(zonamethod，亦称段法)与求目标函数最小值的共轭梯度法结合，进行非灰系统当量灰吸收系数的反演。

For the four heavy metals in the fly ash, more than 90% of Pb had already been volatilized even with no chlorination agents, and the effect of chlorination agents on the volatilization of Zn was greater than that of Cd and Cu.

在原灰中，Zn的挥发率受氯化剂影响最大，其次是Cd和Cu，在未添加氯化剂的情况下，飞灰中的Pb几乎全部挥发。

Whilst for the four heavy metals in the water-washing fly ash, the chlorination agents obviously affected their volatilization, especially of Zn and Cu, and more than 95% of the four heavy metals were volatilized after spiking chlorination agents.

水洗灰中重金属的挥发率受氯化剂影响更明显，其中Zn和Cu最为显著，添加氯化剂后，水洗灰中4种重金属的挥发率最高均达到95%以上。

The fluidized cooler is used to cool the bottom ash from furnace temperature down to a temperature acceptable for the bottom ash handling system.

液态化的冷却器是用来把炉底灰的高温降低到底灰处理系统能接受的范围内。

Ash melting furnace using carbon combustion heat can be recommended for fly ash from hospital waste incinerator facility.

大型生活垃圾发电厂因自身能发电而且焚烧灰量大，宜选用电热型熔融炉，医疗垃圾焚烧飞灰含有较多的活性炭，宜选用残余炭式熔融炉。

The effect of mineral admixtures on the expansion due to ACR was studied. The results show that the expansion can not be suppressed by natural zeolite, ground blast furnace slag and silica fume, however, it can be suppressed by some kinds of fly ash and the composites of natural zeolite and fly ash, ground blast furnace slag and silica fume respectively.

试验了矿物质掺合料对ACR的抑制作用，沸石、矿渣、硅灰均不能有效地抑制ACR，而某些粉煤灰及沸石与粉煤灰、矿渣、硅灰的复合对ACR有抑制作用。

By using AAS and XRF, the contents of Cr, Pb, Mn, As, Se, Hg, Cd, Zn in raw coal, bottom ash and fly ashes are measured quantitatively in a 220 t/h pulverized coal boiler. Factors affecting the distribution of trace elements are investigated, including fly ash diameter, furnace temperature, oxygen content and trace elements' characters. The coefficient of Meij is also improved to more directly show element enrichment in combustion products. Elements may be classified into three groups according to volatility features of trace elements.

采用原子吸收分光光度计和X射线荧光光谱仪，定量测定了电厂煤粉炉中原煤、底渣、飞灰中Cr、Pb、Mn、As、Se、Hg、Cd、Zn等微量元素的含量，分析了飞灰粒径、炉膛温度、炉内含氧量、微量元素自身性质对微量元素赋存、挥发特性的影响，并根据元素的挥发特性将元素进行分类，得出表征微量元素排放特性的3种数值，并与我国和欧盟垃圾焚烧微量元索排放标准相对照。

An important part of our Ash Wednesday service will be the imposition of ashes, as a sign of mortality and repentance.

在圣灰日崇拜的一个重要步骤是将要抛洒圣灰，作为死亡和悔改的标记。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
