Fe2O3 acts as an activator more than a catalyst in the desulfurization reaction with lime. Fe2O3 acts as the "activation center" around which CaO particles are sulfurized. The new dispersal formation mode of product differs from the compact layer that used to be. And the pore structure of product layer on the surface of lime particles is optimized, which makes SO2 penetrate into core parts of lime more easily. As a result, the desulfurization reaction is developed deeper into the core parts of absorbent.

氧化铁所起的是改变石灰颗粒表层产物生成方式的活化作用，使反应生成物不会形成一个致密的外壳，而以氧化铁为活性中心进行硫化反应，形成了分散的硫酸钙产物堆积，改善了硫化过程中的表面孔隙结构，减少了石灰颗粒表面硫化产物层对反应气体向石灰颗粒内部扩散的阻力。

Platelets play a central role in the spontaneous process of atherothrombosis and in the formation of thrombi following coronary stent implantation.

在动脉粥样硬化血栓形成的自发过程及血栓形成后的血栓冠状动脉支架植入术中血小板发挥中心作用。

The data from stress box indicate that the observed values usually are smaller than the theoretical ones, and the relationship between the vertical or lateral stress and the fill soil thickness can be described in a power function curve: a- a hb. The fact that the soil stress is bigger in the portion adjacent to the central part of gully and becomes smaller in the portion close to the side illustrates that the gully has an apparent unburdening effect. From the monitoring results of the settlement deformation during and after constructingperiod, the study conducts statistical system analysis and evaluation on the change of settlement with time.

根据压力盒测试结果表明，测量值往往比实际的理论计算值小，填土的竖向和侧向土压力与填土厚度可以用幂次型曲线表示：σ=ah~b愈向沟谷中心部位，土压力值愈小，愈向沟谷边缘，土压力数值越大，说明沟谷边坡具有明显的卸荷作用；根据施工期和工后期的沉降变形监测数据，对路堤内各测点的竖向沉降随时间的变化规律进行了数理统计系统分析和总结，工后期路面沉降和时间关系可用对数曲线表示：S=aln+b，并根据此沉降规律对高填方加筋土路堤的工后沉降进行了预测。

However, IDC believes that with all of the current focus on reducing power consumption within the data center, the role of the distributed office environment within the Green IT ecosystem in Asia/Pacific including Japan region has been largely underplayed.

然而，IDC 认为由于当前降低能耗的所有焦点都放在了数据中心，绿色 IT 生态系统中的分布式办公环境的作用在整个亚太区被极大地低估了。

In fact, either in the society of pre-nation age, or in different nations and periods of nation age, various norm patterns are needed to satisfy the needs of various social units, such as family, nation, patriarchal clan and community.

这种以制定法为中心的国家主义法律观自有其合理之处，但它却忽视了一个重要而基本的社会事实，那就是，国家制定法在任何社会中都只是法律生活的一部分，无论其作用多么重要，它们也只能构建部分法律秩序。

After 90's, the pattern of big tourism, big market and big industry of Chinese have been primary formed . A large number of tourism regions with different characteristics appear one by one. The main bodies of different tourism regions carry out abroad and deep cooperation. The cooperation's form are various, and the content are all-including, and the mechanism become more and more perfect, the effect are more and more obvious.

始于20世纪70年代末期的改革开放，使中国经济迈上快速发展之路，促使中外经济文化交流的不断扩大，旅游业在这样的背景下迎来了发展的春天。1984年中共中央提出发展旅游业&五个一起上&的方针政策，在经济发展、开放扩大、政策英明的综合作用下，20世纪80年代末期中国国内旅游形成了的以广东开放地区为先导、以江南繁盛之地为中心，神州大地、自南向北、由东往西的蓬勃发展之势。

The building of Beijing,"deputy city center" to create decentralized ease the important function of the central area of the space vector, not only conform to the internationalization of the general trend of urban development, but also to ease the central area of Beijing city functions, optimizing the layout of urban space will play an important role.

建设北京&城市副中心&，打造分散疏解中心区功能的重要空间载体，不仅顺应了国际化城市发展的大趋势，而且对疏解北京中心区城市功能、优化城市空间布局具有重要作用。

Based on the analysis of one type high-speed gas bearing working principle, the bearing diameter of axle static carrying force model was set up, and the relationship between bearing clearance gas flow rate, intensity of pressure and orifice radius were analyzed, along with the diameter of axle movement tracking under the centrifugal force in the low rotating speed was found.

在分析一类高速气浮轴承工作原理的基础上，建立其轴径轴承的静态承载力模型，并据此分析出轴承间隙中气体流量、压强与节流孔孔径间的相互关系，以及在低速运转下受离心力作用的轴径中心运动轨迹。

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。
