结果表明高Nb-TiAl合金有较好的锻造性能，变形抗力随变形温度的升高和应变速率的降低而降低。

The basic reason for oxygen concentration reduction in heavily Sb-doped CZSi was that oxygen solubility decreased when element Sb with larger radius doped degenerately into silicon crystal.

为解释重掺锑硅单晶中氧含量较普通直拉硅低，且随着掺锑量增加，氧含量下降，而重掺硼硅单晶中氧含量并不降低这一实验事实，应用热力学计算，得到重掺锑硅单晶生长时，生成Sb〓O〓的反应不能自发进行，因此不会因Sb〓O〓的大量挥发而使重掺锑硅单晶中氧含量降低。

As for the dehumidify ing conditions, the condensing rate for the humid air increases with Reynolds number but decreases as the inlet temperature of cold water increases.

同时湿盘管的热传量及除湿率亦也随著冰水入口温度的降低而增加，显热比随著冰水温度的降低而减小。

In the batch incubation with addition of Asadsorbing ferrihydrite, the presence of arsenicresistant denitrificator caused an increase in concentrations of Fe and Mn, a decrease in concentrations of NO-3 and As, and a high ratio of As to the total As.

在吸附有砷的水铁矿体系中，反硝化菌所产生的反硝化作用可导致溶液中NO-3含量的降低、Fe含量的升高、As含量降低，且As所占比例增加。

The chemical activating mechanism of UA is that CG can stimulate pozzolanicity more effective than gypsum because of higher solubility and looser crystal structure; but CG has poor property on retardation setting, and this shortage can be solved by mixing with gypsum; CS can offer alkali activity, which can depolymerize silica and aluminum glass, and benefit for other activity methods and overcome the disadvantage of HF on setting time; Sodium sulfate improves early strength greatly but loses the final strength. NF can improve both early and final strengths.

联合激发技术的化学激发机理是，煅烧石膏溶解度高及晶体结构松弛，比天然石膏的活性激发效率高，但降低石膏的缓凝作用，与天然石膏混合既可提高活性又能保持缓凝作用；干法电石渣提供碱激发，促进高钙灰中硅、铝玻璃体解聚，并克服高钙灰对凝结时间的不利影响；硫酸钠虽然早强作用明显，但使后期强度倒缩，NF使各龄期活性都得到提高；磨细的物理激发使高钙灰大颗粒中的CaO和富集碳组分被磨细、分散，活性增加而危害性降低。

Desaturate the new texture layer, change the blending mode to overlay and lower the opacity to about 50%.

降低新的材质贴图的饱和度，改变叠加模式为overlay然后把透明度降低到50%。

It is concluded that the ultrafiltration preconcentration combining with multieffect evaporation is a promising concentration procedure for straw black liquor, which can not only reduce the concentration costs, but also improve the subsequent evaporation and combustion operation due to the desilicification and purification of ultrafiltration.

两种膜比较，磺化聚砜膜更易清洗，而且水通量大。5）超滤浓缩后，黑液中木素的浓度和纯度大大提高，超滤是从黑液中分离木素的理想方法。6）与多效蒸发相比，用超滤法浓缩麦草黑液可降低能耗70~85%，若用于黑液的预浓缩，再结合多效蒸发，不仅可以降低黑液的浓缩费用，而且由于除硅和纯化作用，会大大改善后继的蒸发和燃烧的操作。

The method can reduce greatly the job amount of fine milling, the ore milling cost and power consumption and raise alumina recovery rate, and is economically beneficial compared with available foam floating desiliconization technology.

本发明的方法，大大降低了细磨作业量，降低了磨矿费用和能耗，有效地提高了氧化铝回收率，与已有的泡沫浮选脱硅技术相比，经济效益显著。

Some factors to influence the silicon content of hot metal were proposed on the basis of the experiment in the lab: increasing the binary basicity is favorable to desiliconization; the oxide in slag debases the silicon activity and is of great advantage to desiliconization; Al2O3 and SiO2 are disadvantageous to desiliconization, the volatilization content of SiO2 in coke increases with increasing smelting temperature, leading to increase the silicon content of hot metal; the silicon content of hot metal increases with increasing the drip zone's altitude.

在实验室进行了降低铁水中硅含量的实验，得到了铁水中硅含量的影响因素：提高二元碱度有利于降硅；增加渣中氧化物可降低SiO2的活度有利于降硅；Al2O3和SiO2不利于降硅；冶炼时焦炭中SiO2的挥发量随温度的升高而增多，使铁水中硅含量增加；随着滴落带高度的增加，铁水中硅含量不断增加。

The predictions of dichotomic models showed that continuing chemotherapy(coverage between 50%-60%)could reduce infection intensifies to 30%-80%,but could not change local transmission potential;therefore,the termination of chemotherapy would be foilowed bv bouncing back of transmission.

经二分法效验的模型预测显示连续化疗(50%～60%的覆盖率)在6年内能将感染强度降低30%～80%，但不能降低传播潜力；所以化疗一旦停止，传播即反弹。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
