The experimental study on higher-temperature fusing properties of coal ash and materials shows: it is high ash content and low volatile matter content rather than the fusion point value that are the main factors which influence primary the temperature of liquid phase of cement raw meal.

本文通过灰熔点的实验方法，进行的煤灰及物料高温熔融性研究表明，煤灰灰熔点的高低并不是影响水泥生料液相初析温度的最主要原因，而煤中的高灰分及低挥发分却是关键因素。

The result shows that: both coal gangue and lime have great influence on the strength of cement mortar.

结果表明，煤矸石和石灰掺入对水泥砂浆的强度具有较大的影响。

This type of sulfate attack damage can be suppressed by fly ash, while it is accelerated by coal gangue.

粉煤灰对水泥基材料的这种硫酸盐侵蚀破坏类型有改善作用，而煤矸石对其有不利影响。

Using the fluid mechanics theory, the Gauss filtration governing equations are presented based on the incompressible Navier-Stokes equation in primitive variables, which are discretized using standard third-order accurate Galerkin finite element scheme in space and discretized using finite differencing scheme in time.

为了考证数值模拟结果的正确性，对水泥在圆弧弯管中的气力输送气固两相流动采用了等速取样和等截面法进行了三种工况的试验研究。试验结果表明，竖直上升弯管出口颗粒浓度在弯管外侧脊线附近颗粒浓度特别高，其余部分相对比较均匀且浓度较低。

应用有限元法对某型水泥磨机主减速齿轮箱箱体的应力和刚度进行了计算。

This paper presents the application of RCC in Genevan and Wan an projects and shows that it can satisfy all technical requirements of mass concrete.

结合碾压砼在清江隔河岩和万安工程上的应用，本文阐述它可用于大体积砼，且比常规大体积砼水泥用量少、水化热温升低，有利于大面积通仓浇筑、加快施工速度。

Amelia Cerezero, who lives in a one-storey cement shack in the village, looks after her five-year old grandniece.

Amelia Cerezero，她住在村中一间水泥平房中，并且照顾着自己五岁的小侄孙女。

The result also showed that return treatment is better than taken treatment within different treatments. 4. According to the experiment when the plant was harvested(In March 25th,2009), it was found that the rape with NPK treatment,especially with NPK-T treatment in Quaternary red soil and in granitization red soil, grew abnormality or dead in the centre of district(80%),which yield was extremely low,but had some to the remaining(20%) close to the cement ridge.Among the three types of parent material,eighteen districts,Dischaemum Schreb of gramineae plants could only grow in granitization red soil with NPK treatment,and the other sixteen districts were little or even not.The rape planted in Quaternary red soil with NPK treatment got disease especially in the centre of the district.

其次是M处理，CK最低。3、三种母质种植油菜均表现为：归还处理好于带走处理；4、据试验收产时（2009年3月25日）发现：四纪红土和花岗岩二种母质的NPK处理的油菜除靠近水泥梗边行长有部分油菜外（占小区面积20%），小区中间（占小区面积80%）的油菜生长不正常或死亡，产量极低；三种母质共18个小区，只有花岗岩母质的NPK处理长有禾本科植物马唐草，其余16个小区很少或没有；四纪红土NPK处理油菜病害严重。

A borehole was drilled in granodiorite rockmass at Fangshan, Beijing, China. The depth of the borehole is 301m with diameter of 110mm.
