无水石膏

It is of great economic importance because it assists in the formation of a ""trap"" structure for oil accumulation, in addition to its associated deposits of anhydrite, gypsum and sulphur.

这在经济上有极大的重要性，因为它可被用来帮助"圈闭"结构的形成，在形成无水石膏、石膏和硫磺的同时，有助於石油的积聚。

Preparation of dehydrated gypsum phases of β-series in forms of hemihydrates, anhydrite and anhydrite in laboratory is presented in the paper.

本文介绍了β系列三种石膏脱水相——半水石膏、无水石膏和无水石膏的试验室制备条件。

The properties of anhydrite Ⅱ with white protland cement as accelerating agent are studied,and the durable stucco gypsum in outdoor condition are prepared successfully.

研究白水泥等作激发剂的难溶性无水石膏的性能，并制备出用于室外条件下的耐久型粉刷石膏。

PG was used to produce different types of binding materials as β-hemihydrate gypsum,Ⅱanhydrate gypsum and α-hemihydrate gypsum and the relevant factors were also studied systematically including the pretreatment methods of raw material, preparation process, the material properties, the mixing proportions, curing conditions and the hydration mechanism of different systems.

对磷石膏制备胶结材进行了深入、系统研究，包括β-半水石膏、Ⅱ-无水石膏的原料预处理方式、制备工艺、性能及其复合胶结材配比、养护、性能与水化硬化机理，α-半水石膏的制备工艺及其性能影响因素，二水磷石膏改性胶结材的配比、养护、性能及其改性机理。

Model predictions are qualitatively consistent with experimental observations of regions of the buffer exposed to the highest temperatures,which indicate precipitation of secondary phasesanhydrite ± amorphous silica(opal-CT ± calcite and alteration of Na-smectite to Ca-smectite ± saponite.

模型的预测值能够定性地与高温下缓冲区的观测试验值相吻合，表明次生矿物的沉淀无水石膏±无定形二氧化硅(opal-CT±方解石和由 Na 基蒙脱石变为 Ca 基蒙脱石±皂石的相交替过程。

The major hydrate is CSH gel under this condition. Curing of mortar in water increases the hydration degree of the binder with or without thermal proceeding. In addition to more CSH gels, some ettringite is formed.

试样脱模后在60 ℃蒸养6 h将阻碍无水石膏向二水石膏转化，但促进粉煤灰的火山灰反应，此时主要水化产物是CSH凝胶；继续水养护进一步促进胶结材的水化，除生成较多CSH凝胶外，还有部分钙矾石生成。

In this study, a mineral shrinkage-compensating admixture for use in concrete is developed from some industrial wastes (fly ash and ground granulated blastfurnace slag), together with some gypsum anhydrate. It takes use of the formation of ettringite.

主要研究利用某些工业废弃物和适量的无水石膏，基于钙钒石的形成而引起的膨胀势能，制备一种用于道路混凝土的收缩补偿水泥添加剂。

It shows that gypsum is stable at the pressure less than 407 MPa; and then gypsum begins to dissolve with the increasing pressure. Gypsum stops dissolving and phase transition happens (gypsum-bassanite) to some degree. After phase transition, bassanite disappears with the rising pressure.

结果表明：压力小于407 MPa时，石膏的形态无明显变化；随着压力的升高，石膏开始溶解，溶解至一定程度，石膏发生了向半水石膏转化的相变；相变完成后，半水石膏继续溶解至消失。

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。

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。

He is the most remarkable man that I have ever known.

他是我知道的人中最值得注意的人。

Increased appearance of lymphocele was noticed in patients with diabetic nephropathy, congenital malformations of the urinary tract, and inflammatory diseases, including glomerulopathy and extraglomerular ones, after high-voltage radiotherapy and after removal of the renal graft.

经过高压放射疗法和切除移植肾后，在糖尿病肾病患者、泌尿系统先天性畸形患者和炎症患者身上发现淋巴囊肿有所增加，包括肾小球病和球外疾病等。
