METHODS: Five plaster supramaxillary abutment tooth models were scanned and reconstructed by 3D laser scanner.

采用激光扫描仪对上颌1，2，3，5，6共5颗牙的基牙预备体石膏代型进行三维扫描，并用Surfacer软件测量相关指标，用游标卡尺在石膏代型上测量基牙预备体的各个相关指标，用三种不同的方法分析系统的可靠性、可重复性以及扫描精度。

METHODS: Five plaster supramaxillary abutment tooth models were scanned and reconstructed by 3D laser scanner. The 3D shape of the models was measured by Surfacer10.5 software and the plaster models were measured manually with vernier caliper. The data were statistically analyzed.

The XRD and SEM/EDX analyses demonstrated that minerals in Beijing PM10 were clay and quartz, plagioclase, potassium feldspar, albite, calcite, dolomite, hematite, pyrite, magnesite, gypsum, and laumontite, in descending order.

XRD及 FESEM/EDX单颗粒分析表明，北京市PM10中的矿物颗粒以粘土矿物和石英为主，另外还有斜长石、钾长石、钠长石、方解石、白云石、赤铁矿、黄铁矿，菱镁矿、石膏、浊沸石等，矿物颗粒表面的硫化现象常见。2002特大沙尘暴颗粒物中的矿物的含量自大到小分别为粘土矿物、石英、斜长石、方解石、钾长石、赤铁矿、黄铁矿、角闪石和石膏。

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。

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。

In this paper, the instantaneous deformation and failure characteristics, creep characteristics of gypsum breccias under different confining pressures and stress levels are studied by means of conventional triaxial compression tests and uniaxial and triaxial compression creep test s.

本文通过对石膏角砾岩进行不同围压下的常规三轴压缩试验，单轴以及不同围压下的三轴压缩蠕变试验，研究了石膏角砾岩的瞬时变形及破坏特征，在不同围压及应力水平下的蠕变特征等。

ABSTRACT Mechanical properties of soil stabilized cement made from kiln ash, which consists of clinkers made from kiln ash only or the kiln ash with CaSO4-CaF2 compound mineralizer and certain amount of gypsum are studied. Moreover, the effects of burning temperature and gypsum content on the strength of the stabilized soil with kiln ash cement have been researched.

摘 要 研究了用纯窑灰、掺CaSO4-CaF2复合矿化剂的窑灰烧熟料与适量石膏混合配制的窑灰水泥稳定土的力学性能，并探讨了烧温度和石膏掺量对窑灰水泥稳定土强度的影响。

I plant construction since 1988, through continuous technological innovation of products now Jinzhou City, Hebei Province Lafarge gypsum plaster MILL is well-known in North China specializing in the production of gypsum plaster board manufacturer, is a private enterprise , More than 200 employees, all types of professional and technical personnel 30, 8 million yuan in fixed assets, more than 20 million yuan in output value.

我厂自1988年建厂以来，通过不断的技术革新现在的产品河北省晋州市拉法基纸面石膏板厂是华北地区著名的专业生产纸面石膏板的生产厂家，属民营企业，现有职工200余名，各类专业技术人员30名，固定资产800万元，年产值超过2000万元。

Consumer Product Safety Commission, the agency charged with protecting Americans from unsafe household products, last week released interim remediation guidelines and said certain Chinese drywall samples emitted hydrogen sulfide, a flammable gas with a rotten-egg smell, at rates 100 times greater than non-Chinese drywall samples.

Consumer Product Safety Commission上周发布临时性补救指导，称中国的石膏板样品发出的硫化氢，是非中国产石膏板样品的100倍。硫化氢是一种伴有臭鸡蛋味的可燃气体。美国消费者商品安全委员会是一家负责保护美国人免遭不安全家用产品侵害的机构。
