At present, China's traditional concrete products, such as concrete and reinforced concrete pipes, self-stress pipes, prestressed pipe, reinforced concrete pole, and prestressed concrete poles, prestressed concrete sleeper, asbestos cement, and in the small Bova Bova, asbestos cement tubes, etc., these products production capacity and actual production, most of them can meet the needs of the market, there are many species more than the actual market requirements.

目前，我国传统的水泥制品，如混凝土和钢筋混凝土排水管、自应力管、预应力管、钢筋混凝土电杆和预应力混凝土电杆、预应力混凝土轨枕、石棉水泥小波瓦和中波瓦、石棉水泥管等，这些产品的生产能力和实际产量，大都能满足市场需要，有许多品种已超过市场的实际需要量。

At present, it always directions the mixture ratio and aggregate grade of cement-fly ash bound macadam mixture according to the experience of lime-fly ash bound macadam or cement bound macadam mixture. It is hard to avoid wasting material and labilization of the construct quality. Thereby it made the applications of cement-fly ash bound macadam mixture base is not extensive in road surface structure of our country.

目前，按照二灰、水泥稳定碎石的经验来指导水泥粉煤灰混合料的配合比及集料级配，难免造成施工过程中的盲目用料或施工质量不稳定，从而使得水泥粉煤灰混合料基层在我国路面结构中应用不多。

On the contrary, the setting time of the composite cement slurry delayed greatly and their fluidity were increased significantly after blended with lead nitrate.

与此相反，掺Pb(上标 2+)后复合水泥净浆的凝结时间明显延长，胶砂的流动度明显增大，早期强度也明显降低，分析认为这主要是水化过程中形成了含Pb沉淀物，它们包裹着水泥颗粒，形成致密的不途水层而使水泥水化受阻所致。

Marrow cavity is the place where bone cement fusion takes place, so its preparation is important to improve bone cement filling quality.

摘要背景：提高骨水泥与骨界面的融合可降低假体松动率，骨髓腔是骨水泥融合中的接受腔，其准备过程是提高骨水泥充填质量的关键。

The results show that the compound grinding aid consisted of JA and JF has high efficiency which may increase the output of cement mill by more than 12% and energy saving by more than 10%;it is possible to activate the slag and more slag can be added in slag cement.

结果表明，由JA、JF组成的复合助磨剂，AF助磨效果较好，使水泥磨产量提高12%以上，节电10%以上；且可以激发矿渣活性，提高矿渣水泥中矿渣的掺量，当矿渣掺量达50%时，仍可确保生产425R矿渣水泥。

This paper introduced the design and improved requirement, system structure, operation principle and main technical specification of the automatic cement intensity of breaking tester.

笔者新研制成功的机电一体化新一代SYQ型液压式全自动水泥抗压强试验机和SYZ新型全自动水泥抗折强度试验机产品，由计算机自动控制，其性能达到国内领先水平，并且二者可以合成一体或者联机，这里介绍了全自动水泥强度综合试验机的系统构成、工作原理和主要特

Taking the tests of the cement slipform concrete construction in Hai nan province, it discusses the selection of the optimum mixture ratio thus acquiring the amount of cement, sand ratio, gradation type and the use of additive.

通过总结海南省公路水泥混凝土滑模施工配合比试验与实践，探讨水泥砼的最佳配合比，以便确定水泥用量、砂率、级配类型、外加剂用量等指标的合理选用。

Each time after putting to (the instrument with the set of Yamshidi-Nadel provided by Kypho of America for injection of bone cement into the vertebrae; each putting could contain about 1.5 mL bone cement) inject bone cement into the vertebrae, the pressure P was not very high, with 500 kPa bar below for majority and the effect caused showed a significant statistical difference (P.01). Whereas, the pressure within the area of the vertebral P value was not high either, the majority was 10.00 Unit lower, which also led to the effects of significant difference (P.01). Both two states showed partial distribution. After making the statistical analysis to the casual two puttings between the first, second, third and fourth putting of each vertebrae, there existed the general differences. The differences were also found between other puttings (a.0083) on the statistics basis apart from between the first and second and between the third and fourth.

结果 每个椎体的椎体成形术均达到临床评价要求，每次推杆（美国Kypho公司提供标准椎体成形术中Yamshi-Nadel套系中推注骨水泥入椎体的器具，每具推杆可容纳骨水泥约1.5mL）推注骨水泥入椎体时所产生的椎体内的压力P不是很高，多数在0.50 bar以下，其所导致的效应具有显著的统计学差异(P.01)，而每次推杆推注骨水泥入椎体时的椎体内压力面积值P也不是很高，多数在10.00 Unit以下，其所导致的效应具有显著的统计学差异(P.01)，两者均呈偏态分布；而且，对每例椎体的第一、二、三、四杆之间两两予以统计学上的分析，在总体存在差异有统计学意义的基础上还发现除第一和二杆、第三和四杆之间外，其他各杆之间存在着差异(a.0083)。

At present, cement grinding system with roller press, especially combination grinding system have become one of cement grinding preferred schemes in large-scale cement production line.

目前，带辊压机的水泥粉磨系统，特别是挤压联合粉磨系统已成为了大型水泥生产线水泥粉磨的优选方案之一。

The split between the two groups can hardly be papered over.
