高贝利特水泥的研究，是中国建材院负责的国家&九五&重点科技攻关成果，顺应了水泥胶结材的发展方向。

To investigate a new method of preparing the PCHA bone cement, and to test its physicochemical properties, and to evaluate its degrading, osteogenous ability and compressive strength.

目的 探讨原位固化制备多孔生物材料的新方法；制备多孔碳酸化羟基磷灰石骨水泥；完成PCHA骨水泥的理化性能检测；验证PCHA的降解性能、成骨活性和强度变化。

Therefore,it is absolutely necessary that phase composition of low temperative white cement is researched by thermal analysis.

本文用同步热分析方法对重庆低温白水泥的原料，生料、热料和水泥的水化产物进行了较全面的分析。并适当选用了化学分析，岩相鉴定和X衍射分析方法进行配合。

If the prosthesis is unstable then revision is necessary to a stemmed device, cemented or uncemented, in order to internally brace the fracture.

如果假体是不稳定的，为了对骨折起到内部支撑的作用，则必须应用骨水泥或非骨水泥的带柄假体进行翻修。

If the prosthesis is unstable then reision is necessary to a stemmed deice, cemented or uncemented, in order to internally brace the fracture.

如果假体是不稳定的，为了对骨折起到内部支撑的作用，则必须应用骨水泥或非骨水泥的带柄假体进行翻修。

In addition, finite element modeling and direct measurement of strains within proximal medial cement mantles hae demonstrated only slight increases in cement strain with the use of stems with enhanced offset.

另外，有限元模型分析及对近端内侧骨水泥套内侧应变的直接测量表明使用加长偏距的股骨柄对骨水泥的应变仅有轻微增加。

The proportion of perlite in the concrete mix varies but a cement:perlite ratio of 1:6 is considered standard for roof deck applications. Perlite also improves the flow characteristics of cement or concrete and so is used in self-leveling floor screeds Figure 2

使用时比例各有不同，但是对于屋顶板，标准的水泥对珍珠岩的比例为1：6，因为添加珍珠岩可以改善了混凝土和水泥的流动性，因此也用于自流平地坪

The effects of sintering temperature on the petrographic structure, mineral composition, crystalline phase and solid solubility solution composition of clinkers were studied by means of microscope, XRD, EDS and chemical analysis.

检测了不同烧成温度制成的低热水泥的物理性能及水化速率，并采用岩相分析、XRD、EDS﹑化学分析方法研究了不同烧成温度对低热水泥熟料岩相结构﹑矿物组成、矿物晶型及矿物固溶组分的影响。

Third, permeability coefficient of soil cement is decreasing with the content of cement.

水泥的掺入量对水泥土的渗透系数有明显影响，随水泥的掺入量增加而减小： 4。

The increase of the strength of slag Portland cement is influenced by the factors of the composition, structure, the quality of slag, mixture, etc.

阐述矿渣硅酸盐水泥的强度增长是受水泥熟料的组成、结构、矿渣质量与掺量等因素的影响。

Methods: Five patients with parkinsonism or dystonia were assigned to general anesthesia using an modified endotracheal tube.

本实验依照人体实验之相关规定进行，五位患有帕金森氏症或肌张力异常的病人接受神经立体定位手术。
