The physical and chemical properties of the sorbents were characterized by scanning electron microscope and mercury porosimeter. Their sulfation characteristics were tested on a bench-scale fluidized bed reactor.

在小型流化床反应器中对5种钙基吸收剂的脱硫反应性能进行了实验研究，并利用扫描电镜和压汞分析等方法对吸收剂反应前后的微观结构进行了分析。

Three kinds of typical shells, such as scallop, whelk, bloody clam, as well as one kind of limestone were chosen to perform desulfurization and calcination experiments on the fluidized bed platform.The microstructures of the tested samples were mensurated by means of one mercury porosimeter.

在流化床上对3种典型贝壳---扇贝、海螺、毛蚶以及一种石灰石进行煅烧脱硫试验研究，并利用压汞仪测定试验样品的微观孔隙结构，通过最可几孔径、孔隙率、比表面积等3个结构特征参数对微观结构进行定量分析；另外，还对试验样品的化学成分进行了分析。

A new desulfurization apprach for pulverized coal combustion is introduced in this paper; pulverized coal is first burn in a precombustion furnace under oxygen deficient condition (about 30% air needed in boiler is provided for precombustion), in precombustion moust of sulfur in coal is decomposed and oxidized, and evolved, the sulfur evolved is trapped in a desulfurizing fluidized bed by calsuim, and then the char and gas are introduced to the boiler furnace for complete combustion.

本文提出了一种煤粉燃烧脱硫新方案，利用煤中硫优先氧化分解释出的原理，用少量的空气（大略为锅炉实际空气用量的30％），在一前置燃烧室中，使煤粉中硫的绝大部分被分解氧化，释放出来，释放出来的硫在脱硫流化床中被石灰脱硫剂脱除，未燃烧的炭粒与烟气再吹进锅炉膛中完全燃烧。

RS were respectively used to prepare the ibuprofen pellets and the pseudoephedrine hydrochloride pellets by fluidized-bed technology.

RS为骨架和包衣材料制备盐酸伪麻黄碱缓释微丸，并运用统计软件SPSS进行处方和工艺的正交设计优化。

There are a few defects in existing processes of biomass gasification, for example using air as gasifying medium, N2 and tar content of the gas is high, and the calorific value is as low as 5000kJ/N in3. The technology of a circulating fluidized bed is still tentative at laboratory level. Through direct pyrolyze biomass, we can get product gas with high heating value (l4000kJINm3), but gas yield ratio is low (O.35m3/kg).

目前的生物质热解气化技术的现状是：以空气为气化剂的气化方式，得到的气体N_2和焦油含量高，热值一般在5000kJ/Nm~3左右；流化床气化工艺操作复杂，推广应用存在较多困难；直接干馏热解，虽气体的热值高（14000kJ/Nm~3），但产气率低（0.35m~3/kg）。

The results of the tests in this paper show ANAMMOX process has practical engineering value. The ANAMMOX process could be established through recycle of the effluent from the sedimental tank to the anaerobic fluidized bed, and the TN removal efficiency of A〓/O could be enhanced by 15%.

本论文的实验表明厌氧氨氧化过程具有实际工程意义，利用好氧沉淀池出水回流到厌氧池，可以实现厌氧氨氧化过程，系统的总氮去除率可提高15％。

Studied in the paper are the performance, separation efficiency and pressure loss of a uniflow square shaped cyclone separator which can be directly and easily installed on the water wall of a circulating fluidized bed boiler.

对可与循环流化床水冷壁直接结合而易于布置的下排气方形旋风分离器的性能指标：分离效率、压降等进行了研究。

On these grounds, a new method, the divided steping reduction, was put forword to prevent sticking phenomenon for pre-reduced fluidized-beds of smelting reduction, i. e. concentrate is reduced under the temperature and composition of gas first for the thick morphology of iron, to a certain metallized rate, and then for the whiskery morphology of iron.

据此，提出了一种新的旨在预防熔融还原预还原流化床粘结现象的措施——分段还原法，即先将铁精矿置于铁以致密状析出的温度和气氛下还原至一定的金属化率，而后再在铁晶须析出的温度和气氛下进一步深还原。

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。
