石膏

But commonly used product is fireproof, moistureproof the gender is poorer.

家装中客厅的灯池、餐厅的局部造型大都是由石膏板做成，石膏板质轻、价低、施工方便，但常用产品耐火、防潮性较差。

However, because most recent plasterboards are used in internal decoration such as ceiling suspension, or in non-structure components such as nonbearing walls and so on, there is little mature researches on fiber-reinforced plasterboard used as main wall.

然而，由于目前的建筑石膏板大多应用于室内吊顶装饰，或应用于非承重的隔墙等非承重构件，对于可用于室内外承重墙体的纤维增强石膏板的研究还不太成熟。

Under condition of different temperature and sulphur consumption, the brown coal and gypsum can promote oxidation of sulphur,the oxidational rate of sulphul is the highest under the condition of applying brown coal and gypsum;The sulphur is oxidized for SO42~ the oxidational rate of sulphur during 0-15 days' incubtation was the highest on the whole,reach the maximum basically within 30 days,up to the extension of time,SO42"""" the content is reduced to some extent;Final SO42 -content, Ig sulphur / kg treatment of soil greater than 0.5g sulphu/kg treatment of soil,become multiple increase,the sulphur is higher than the room temperature in the efficiency of oxidizing of 30 degrees Centigrade (10-20 degrees Centigrade).

在不同温度和硫磺用量的条件下，褐煤与石膏对硫磺的氧化有促进作用，其中褐煤与石膏配合施用对硫磺氧化的促进作用最大；在硫磺氧化为SO_4~(2-)的过程中，0-15天内氧化速率最大，30天内基本达到最大值，随时间的延长，SO_4~(2-)含量有所降低；硫磺在30℃的氧化效率高于室温(10-20℃)，在1克硫磺的处理中，30℃时最大SO_4~(2-)的含量是室温(10-20℃)的1.24倍，在0.5克的处理中有同样的规律，30℃时SO_4~(2-)的含量是室温的1.6倍。

When the alkalinity of soil with gypsum is as well different. The effciency is better with the siol alkalinity increasing.And the alkalinity is higer, the increasing scape is bigger.

碱化度不同，土壤的石膏改良效率亦不同，随着碱化度的升高，石膏的改良效率显著提高；碱化度越高，提高的幅度越大。

The results show that one type of soft slurry occurs on the surface of mortar prism due to addition of limestone filler and a mass of thaumasite and gypsum forms in the slurry.

结果表明：掺石灰石粉使水泥砂浆受侵蚀后表面呈软泥状，主要腐蚀产物为硅灰石膏和石膏，表现为典型的TSA破坏特征，其强度损失率大于纯水泥砂浆。

While plaster is setting the crew cleans up left over plaster on top of rules.

在石膏凝固的同时，工作人员清除尺板上残余的石膏。

In the samples containing aluminum sulphate, some ettringite crystalparticles are formed, which do not match with dihydrate gypsum crystals and increase thedefects in the hardened plaster. The strength decreases sharply with increase of aluminumsulphate amount.

硫酸铝的引入，使石膏浆体中生成部分钙矾石晶体，钙矾石晶体与二水石膏晶体不匹配，从而增加了硬化体内部的缺陷，因此，随着硫酸铝掺入量的增加，硬化体强度的降低比较严重。

Key introduces the CT-121 bubble type spraying tower haze desulphurization craftCT-121 uses the limestone - gypsum (it is in the present world is maturest, most economical, applies broadest desulphurization craft) the aqueous method desulphurization craftIt the sulphur dioxide absorption, the oxidation, neutral, technological processes and so on crystallization as well as dust removal merges to an independent gas - fluid - solid phase reactor in carries onIt the sulphur dioxide absorption, the oxidation, neutral, technological processes and so on crystallization as well as dust removal merges to an independent gas - fluid - solid phase reactor in carries on

与传统的石灰石-石膏湿法烟气脱硫工艺相比，CT-121最大的特点在于鼓泡式吸收塔。它将二氧化硫的吸收、氧化、中和、结晶以及除尘等工艺过程合并到一个单独的气-液-固相反应器中进行。气体进入喷射管，喷射成无数小气泡，形成鼓泡区，从而大大增加了传质面积，提高了脱硫效率。CT-121脱硫工艺能够达到95%以上稳定连续的脱硫率，最低10 以下的粉尘排放率以及优异的可靠性和实用性。问题补充：谁再帮忙给篇，石灰石-石膏湿法烟气脱硫方面的论文文献，谢谢了中英文版的，谢谢了555

In the end, transportation of PAHs in the environmental matrix was preliminarily investigated and discussed according to PAHs data of soils and sediments from a certain region in Shanghai. The result indicated that there are two or more pathways on PAHs transportation in the environmental matrix.

最后，对上海特定地区内PAHs在环境介质中的迁移径途进行了分析讨论，结果表明上海市土壤和沉积物等环境介质中PAHs的迁移存在多种途径。
