查询词典 anhydrite

Compared with general fly ash, CFB boiler fly ash is mainly composed of anhydrite and lime mineral, and its has erose grain and high -CaO and SO3 content.

对比普通粉煤灰性能，CFB锅炉粉煤灰具有颗粒形貌不规则-CaO和SO3含量高，以及以硬石膏和石灰作为主要矿物组成等特点。

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℃. It is the first time to prove that the particles of f-CaO is coated withⅡ-CaSO4 by investigating the process of forming f-CaO, the microstructure, spathic type and optic parameter and the hydrating process.

首次从f-CaO的形成过程、颗粒微观结构、晶型和光学参数以及水化历程等方面证明了f-CaO颗粒被固硫产物无水硫酸钙包裹的颗粒特征，f-CaO颗粒被Ⅱ-CaSO4包裹使其水化速度减慢和活性较低；SO3以Ⅱ-CaSO4形态存在和f-CaO颗粒被Ⅱ-CaSO4包裹均对流化床燃煤固硫渣的活性和体积稳定性产生不利影响。

The temperature of the heated seawater must be less than 150℃.(2) Anhydrite precipitation within the large deposit is mainly controlled by the seawater heating process and the mixing process of hydrothermal fluid and entraining seawater.

2下渗海水被加热及其与来自矿体深部热液流体的混合过程是控制矿体内硬石膏大量沉淀的两个重要过程。

In this study, gypsum used in gypsum moulde is studied so as to study further the influence of a gypsum and plaster, a gypsum and desulphurization gypsum , raw gypsum and gpsum and anhydrite with gypsum on modle gypsum. All conclusions are developmental to the development of porcelain industry.

我们对价格较低的β-半水石膏粉进行各项改性研究，希望以此为基础，再探讨α-半水石膏与天然建筑石膏、α-半水石膏与脱硫石膏混合以及生石膏与天然建筑石膏、无水石膏与天然建筑石膏混合对模型石膏的影响，还讨论了石膏细度对模型石膏的影响，所有的研究结果对我国陶瓷产业的发展有一定的借鉴意义。

The natural result of gypsum plaster and water containing dihydrate anhydrite, and contained chemical components, in particular the complex trace elements, it will cement additives do not have a different series of deep radical solution or condensate, and other phenomena.

而天然石膏因含有二水石膏和无水硬石膏，加上所含化学成分，特别是微量元素复杂，反而会对水泥外加剂不同系列产生不相深溶或急凝等现象。

In this study,α gypsum used in gypsum moulde is studied so as to study further the influence of a gypsum and plaster,α gypsum and desulphurization gypsum,raw gypsum and gpsum and anhydrite with gypsum on modle gypsum. All conclusions are developmental to the development of porcelain industry.

我们对价格较低的β-半水石膏粉进行各项改性研究，希望以此为基础，再探讨α-半水石膏与天然建筑石膏、α-半水石膏与脱硫石膏混合以及生石膏与天然建筑石膏、无水石膏与天然建筑石膏混合对模型石膏的影响，还讨论了石膏细度对模型石膏的影响，所有的研究结果对我国陶瓷产业的发展有一定的借鉴意义。

The carbonate reservoir is characterized by the fact that the azimuth of fractures is related with structural axis, the developmental extent of fractures and structural location are close related to dip of structure, low-dipping structural axis has not growth fractures. Otherwise, growth fractures, density of fractures are related thickness of layer, more thickness, then less density of fractures. Intra-fracture of layer is main. Some marlstone and anhydrite barriers exist in the reservoir, and become some non-connected oil-water system.

结果表明：碳酸盐岩油藏为裂缝的发育程度与构造位置及构造倾角的大小有关，构造轴部倾角小裂缝不发育，构造翼部倾角大，裂缝发育；裂缝发育密度随着单层厚度增加而逐渐减小；裂缝以层内缝为主，穿层大裂缝少；油藏中存在若干泥质灰岩和膏盐的隔夹层，形成多个连通不畅的油水分布系统。

Study shows that compaction and cementation can play a destructive role in Suining formation reservoir,while dissolution and fracturing can play a constructive role in that.The main facies of Suining formation are ferruginous-shale film,anhydrite,dolomite and calcite.The micro-fracture and grain-edged fracture mainly resulted from compaction fracturing,compaction slipping and tectonic dynamic force greatly improve the reservoir permeability.

研究表明：①对遂宁组储层起破坏作用的是压实作用、胶结作用和交代作用，而溶蚀作用、压裂作用则对储层起到建设性作用；②遂宁组最主要的成岩相组合为铁泥膜－硬石膏－白云石－方解石成岩相；③由压实破裂、压实滑动和构造动力形成的微裂缝、粒缘缝有效改善了储层的渗透性。

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。
