水泥的

Fly ash can be used to improve the performance of cement, especially to effectively reduce the total heat of hydration in cement.

粉煤灰能提高和改善水泥性能，特别是能有效地降低水泥的水化热。

A1l the thick adsorption layer,large space steric hindrance,thick solvate layer and stable ξ-potential of ASP adsorbed on cement particles resist the flocculation of cement particles.In addition the early stage hydration of cement is restrained because the—OH ,—NH2 in ASP can suppress the formation of hydrated products such as C-S-H ,Ca2 and ettringite crystals through forming unstable complex compound with Ca2+.So ASP has excellent plasticity-retention capability of concrete.

由于ASP在水泥颗粒表面的吸附层较厚、空间位阻较大、溶剂化层较厚及ξ-电位较稳定等原因，阻碍了水泥颗粒间的凝聚；同时由于ASP含有的—OH，—NH2等官能团与水化产生的Ca2+形成不稳定的络合物，抑制了水化产物C-S-H，Ca2和钙矾石等结晶体的形成，从而抑制了水泥的早期水化，故ASP具有良好的保塑性能。

The Bulk-cement Delivery Tank Truck is not only the vigorously promoted China's main cement transport bulk carriers, but also the main instrument to delivery the cement in the cement of oil and gas wells, the bulk transport can be greatly save the resources, reduce the damage to the environment and reduce air dust pollution, having great strategic significance to the development of our national economy.

气动下灰车是我国大力推广水泥散装运输的主要运载工具，也是有气井固井作业时水泥运载和输送的主要工具，水泥的散装运输可以大大节约资源，减少对环境的破坏，减少空气中粉尘污染，对我国国民经济的发展具有重大的战略意义。

Alite and C4A3S are the main minerals of Portland cement and Alite sulphoaluminate cement.

阿利特和无水硫铝酸钙矿物分别是硅酸盐水泥和硫铝酸盐水泥的主导矿物。

Alite and C4A3 are main minerals of Portland cement and Alite sulphoaluminate cement.

摘 要：阿利特和无水硫铝酸钙矿物分别是硅酸盐水泥和硫铝酸盐水泥的主导矿物。

This paper mainly discussed the hydration mechanism of calcium barium sulphoaluminate mineral, belite cement and belite-calcium barium sulphoaluminate cement.

阐述硫铝酸钡钙矿物、贝利特水泥和贝利特－硫铝酸钡钙水泥的水化机制。

He introduction of α-TCP extends the solidified time of the brushite bone cement, improves scatteres resistance of the bone cement, and increases the pH value of bone cement to some extent.

CP的引入延长了透磷灰石骨水泥的固化时间，提高了骨水泥的抗溃散能力，在一定程度上提高了透磷灰石骨水泥的pH值。

Although the new dry processes are the indicatations of the advanced technology of cement manufacture, there are some internal shortages in the pre-heater and calciner system, which makes the manufacture ineffeciency.

新型干法窑代表了当今水泥生产技术的先进水平。但它也存在着粘结堵塞的顽症，极大地影响了水泥的正常生产。特别是在我国，粘结堵塞问题尤为突出和频繁，新型干法水泥生产受到严重的制约。

And then the author explained that the worry was totally unnecessary by comparing the performance of vertical mill cement and ball mill cement produced by three foreign cement corporations and as well as the related concrete.

基于此，作者进行了国外三家水泥企业立磨水泥和球磨水泥的性能对比及其配置的混凝土性能对比，说明此种担忧是完全不必要的。

This trial test prows that when specific surface remains constant, the output of mill was l0%~15% increased per machine-hour, power consumption reduced 3 kWh/t; when admixture adding rate increased 6%, strength of test samples in each age is equal to that of samples without compound grinding aids added; the initial setting and final setting time are shortened slightly; the workability and fluidity of cement and the grindability of materials are improved remarkably.

结果表明，在比表面积保持不变时，台时产量可提高10%~15%，粉磨电耗成本可下降约3kWh/t；混合材掺量增加6%后，试样各龄期强度与不加复合助磨剂的水泥样强度相当；水泥的初、终凝时间均有所缩短；水泥的和易性、流动性及物料的易磨性能等方面均得到较大的改善。

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。
