煅石膏

SO3 is fixed in ashes at 850~900℃, and it exists in Ⅱ-CaSO4 and has different solubility with the natural anhydrite and the plaster calcined at 400℃.

SO3是在850~900℃的温度下形成的，是以Ⅱ-CaSO4形态存在，且具有与天然硬石膏和400℃煅烧石膏不一样的溶解特性。

Bone morphogenetic protein plaster of paris bone Induction

骨形成蛋白；煅石膏；骨诱导

Old English, denoting a bandage spread with a curative substance, from medieval Latin plastrum (shortening of Latin emplastrum, from Greek emplastron 'daub, salve'), later reinforced by the Old French noun plastre.

①石膏：与水混合后变硬的石膏材料，用于固定或制作身体某部的印模，如牙科石膏或煅石膏；②硬膏〔剂〕：可涂敷于皮肤的糊状混合物，在体温的热度下有粘性。

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。

CaO,SO3 in the clinker and the granularity,specific surface area,granulometric grading,admixture,plaster of cement,these factors will all effect the ISO cement strength,so we have a systemic and optimizing subject.

CaO、SO_3微量组分，煅烧温度，以及水泥制备中的细度、比表面积、颗粒级配、混合材、石膏等对水泥ISO强度都有影响，因此这是一个系统的优化的课题。

Gesso is unripe it is OK to use fire of clear hot have diarrhoea, except irritated stop thirsty, multi-purpose at diseases caused by external factors pyretic, high fever irritated thirsty, lung heats up asthma to cough, gastric fire excessive is filled, have a headache the; forge such as toothache is used can close wet unripe, collect sore is hemostatic, ulcer is treated outside not collect, eczema aches urticant, extreme misery scald, traumatic haemorrhage, it is middling of prescription of doctor of traditional Chinese medicine use blindly mineral medicine, main component is CaSO4 · 2H2O.

梗概： 石膏生用可以清热泻火，除烦止渴，多用于外感热病，高热烦渴，肺热喘咳，胃火亢盛，头痛牙痛等；煅用可以收湿生，敛疮止血，外治溃疡不敛，湿疹疼痒，水火烫伤，外伤出血，是中医方剂中常用的一味矿物药，主要成份是CaSO4·2H2O。

There are four kinds of traditional Chinese medicine often being used: removing carrion medicine, promoting blood flow medicine, warming yang medicine and stypsis medicine. Clinical practice and animal experiment both proved that topical used TCM had preferable curative effect on CSU.

临床常用的外用中药有四类：祛腐类药物，如轻粉、红粉、雄黄、砒石等；活血类药物，如乳香、没药、血竭、三七、琥珀、大黄等；温补类药物，如人参、黄芪、鹿茸、肉桂等；敛口生肌类药物，如炉甘石、珍珠粉、煅石膏等。

The fields of application of calcined FGD gypsum were gypsum wallboard,building plasters,self-leveling floor plaster,etc;The fields of application of uncalcined FGD-gypsum were cement, agricultural soil amendment, etc.

经煅烧的脱硫石膏的应用领域主要有：石膏墙板、建筑灰泥、自流平地板灰泥等；未经煅烧的脱硫石膏的应用领域主要有：水泥、农业土壤改良等。

And under the action of compound activators, it can react directly with slag and sand to produce environment-protecting cementingmaterial with 28d compressive strength above 30Mpa and various kinds ofconstruction products.

本研究由于不需要对磷石膏进行水洗、煅烧等预处理，在复合激发剂作用下可直接与矿渣、砂等作用，生产出28天抗压强度大于30MPa环保型胶凝材料和各种不同的建筑制品，不仅节能，而且不产生二次污染。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
