Requests on resistance of corrosion destructibility of sealing interfaces that related to sealing up and cementing exercises in petroleum engineering are more and more of rigidity. It is urgently needs to resolve all sorts of problems that affect interface bonding quality. Conventional cement slurry design resist the destructive function worse, and can't like to satisfy the request to carry on latter production such as perforation, acidify, fracture etc.

常规油井水泥抵抗破坏的性能较差，不能很好满足水泥环抗冲击振动以及射孔、压裂等各种变形破坏的要求，这在一定程度上限制了小间隙、大位移、定向与水平井等特殊钻井工艺技术的发展，也制约了后期压裂、酸化等诸多开发工艺措施的实施。

The rationality of selecting different type of cement kiln dust chamber fixed in inlet and outlet based on its invest,running cost,adaptability on pollution control,stability,dust removal rate,abnormal discharge,discharge volume,air environmental capacity,environmental quality standard and climate condition on the angle of environmental impact.

从水泥窑大气污染物对环境影响的角度，分析了新型干法水泥回转窑窑尾和窑头除尘器选型的合理性，包括投资、运行成本、对污染物治理和工况的适应性、操作和维修性能、可靠性、稳定性、除尘效率以及非正常排放、污染物排放量、大气环境容量、环境质量标准、气候条件等对环境的影响程度。

On the other hand, having greater absorptivity is the key factor for filtrate reducer to control water filtering, for filterability can not be materially controlled by macromolecular being unable to be effectively absorbed on the surface of cement granules.

在水泥颗粒表面有较强的吸附能力是降失水剂形成堵塞失水通道机制的关键因素，不能有效吸附在水泥颗粒表面的高分子，无法实质性控制体系的失水。

When the amount of water is fixed, GTE reduces with the increasing of water-cement ratio and increases when cement content is fixed. At first, the GTE changes dramatically, but 28 days later, it approaches a stable value.

水灰质量比的影响则取决于水泥用量和用水量的相对关系，当用水量一定时，热膨胀系数随水灰质量比的增大而降低；当水泥用量一定时，热膨胀系数随水灰质量比的增大而升高。

indicate that there is a strength peak when the fly-ash content is 10%.And activity of fly-ash has correlation with the strength of cement fly-ash stabilized hoggin.

水泥粉煤灰稳定碎石是一种新近提出的路面基层材料，其具备了水泥稳定类和二灰稳定类材料的优点，并摒弃了两者的缺点，具有很好的技术性能。

建立接缝无传力杆及设传力杆时水泥混凝土面层结构的三维有限元模型，运用数值分析方法，分析接缝处水泥混凝土面层的荷载应力、弯沉值和弯沉差，研究了地基模量、传力杆直径对荷载应力及弯沉差的影响规律，并对条件相同的计算结果进行了对比分析。

The paper is based on the construction of the express - highway between yiyang and changde in hunan province , aiming at enhancing the serviceability of cement concrete pavement , probing into the structural assemblage of the cement concrete pavement , the roadway drainage system , contraction joint with the dowel bar and precaution of bumping at the end of the abutment . it presents some achievements of the research , including more reasonable structural assemblage and roadway drainage system , the method of setting dowelled bar in contraction joint , putting forward the concept of stage - transition from rigid to flexile behind abutment

本文以湖南省益阳至常德高速公路项目为依托，以提高水泥混凝土路面使用性能为目标，就水泥混凝土路面结构组合、路面排水系统、缩缝设置传力杆、桥头跳车问题的防治等方面开展研究和工程实践，取得了丰富的研究成果，如研究采用了更合理的路面结构组合，设置了较完善的路面排水系统，在国内高速公路上率先全面采用缩缝加传力杆技术，对所有桥涵构造物台背全部采用刚柔过渡技术处理桥头跳车问题等。

Cement and silver sand are used as the basis materials for solidifying galvanized sludge containing heavy metals such as Ni,Cr and Cu,the lixivium test to solidified matter shows that the effect of solidifying galvanized sludge with cement is good.

采用水泥和细砂作固化基材处理含Ni、Cr、Cu等重金属的电镀污泥，对固化块的浸出试验表明：水泥固化该电镀污泥效果良好，固化过程中加入适当的螯合剂KS-3，可以提高固化效果，并对固化块在不同pH浸取剂下的重金属浸出浓度进行了研究。

The partial writing is the cement carving, the relief background is the precipitated and purified slaked lime + resin models the shape; The wall surface is mady with a massive use of cement, rolling, bricks and stones specification modification axed battlements; On the ceiling the egg holds combination reducing the noise and other low technical manufactures, has obtained pure the significant artistic effect.

局部文字是水泥雕刻，浮雕背景是灰膏+树脂塑形；墙面大量使用水泥、压光、砖石规格的改型斧垛；天花板上蛋托的组合降噪等低技术制作，获得了纯净而大气的艺术效果。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
