胶结

The carbonate cements, mainly consisting of ferroan calcite and ankerite, are telogenetic cements.

这样形成的碳酸盐胶结物为晚期胶结物，主要为含铁方解石和铁白云石。

Data obtained by thin-sections analysis, cathodoluminescence emission analysis and SEM/EDX show that carbonate cements seem to be the uppermost cements composed of ferroan sparry calcite and ankerite and are distributed mostly in the depth interval of 100 m below the unconformity, with their contents increasing with the depth.

通过薄片观察、阴极发光、扫描电镜/能谱分析，认为碳酸盐胶结物是研究区砂岩最主要的胶结物成分，其主要类型为方解石和铁白云石，垂向上含量随深度增加而增加，多集中分布在白垩系和侏罗系之间的不整合面之下约100 m的范围之内。

By the use of the component sandstone electric conductivity model, the effect of the pore structure characteristic parameter to cementation exponent m and saturation exponent n in the Archie formula were studied. It can be found the cementation exponent m mainly reflects the pore space size and its sizes distribution. The m is bigger, the pore space is bigger, the throat is simpler, and the reservoir is better.

通过致密砂岩电导模型分析研究致密砂岩孔隙结构特征参数对Archie公式中的胶结指数m和饱和度指数n的影响，发现岩石胶结指数m主要是岩石孔隙空间大小及其大小分布的表征，m值越大的岩石其孔隙储集空间越大，孔喉越简单，储集性能越好；反之，m值越小，岩石储集性能越差。

The circumstances under oil wells have been much more complex than ever . Requests on resistance of erosion destructibility of sealing interfaces that related to sealing up and cementing exercises in petroleum engineering are more and more of rigidi ty .

目前国内许多油田已进入开发后期，开采强度不断增大，井下情况更加复杂，对于石油工程中的固井和挤堵作业涉及的封固界面的抗冲蚀破坏性能要求越来越高，迫切需要解决影响界面胶结质量的各种问题，特别是流体渗流条件下的界面胶结强度的建立和保持问题。

This paper has presented the types and distribution characteristic of the Quaternary glacial deposits on the west side of the Yulong Mountains, which was an important task for the selection and optimization of the Yunnan-Tibet railway line in Northwest Yunnan. Based on lab test of physics and mechanics, the results of engineering properties of moraine/outwash rocks, including the cement composition and their cementation, stability in water, mechanical property, and sound spreading velocity, etc., have been reported, which can not only enrich the research contents of rock mechanics, but also have important practical value for railway construction and water power development in mountain regions.

结合滇藏铁路滇西北段线路比选和优化工作，对云南玉龙雪山西麓第四纪冰川堆积物的类型和分布特征进行了详细的野外调查；在室内物理力学试验的基础上，着重研究了冰碛砾岩的胶结物成分与胶结作用、水稳性、力学性质、声波速度等方面的特性，这不仅可以丰富现代岩石力学的研究内容，而且对本区铁路工程建设和水力资源的开发具有重要的实际价值。

This kind of adglutinate mixed with U expansion admixture can grip anchor bolts tightly even underwater, as can be seen from the pull-out type tests for anchor bolts when the mortar age is over 10 days.(2) The author lays the supporting piles as a arched shape.

将掺加了U型微膨胀剂的砂将作为锚杆水下胶结物，由锚杆龄期10天的抗拔试验结果可以看出，这种胶结物的握裹效果很好。

The coarse clastic rock of the braided channel of the fan-delta plain is formed when sedimentary water body is in the salinity stage of active tectonic period, the cotemporaneous cementation is intense and the cementation of the carbonate and sulphate has intense packing action in eogenetic stage of shallow buried.

构造相对活跃期为沉积水体咸化期，主要发育扇三角洲平原亚相的辫状河道粗碎屑岩，同生期胶结作用强，而浅埋藏早成岩阶段碳酸盐和硫酸盐胶结物充填强烈，致使物性进一步变差，并且不利于晚成岩A阶段的溶蚀作用进行。

The bonding phase of self-fluxing sinter used before was composed predominately of cuspidine and hyaline, mechanical strength of which as well as their bonding strength with respect to magnetite are rather weak.

自熔性烧结矿的胶结相主要由枪晶石和玻璃体所组成，两者的机械强度都较低，对磁铁矿的相对胶结强度也较小。

The full tail sand grouting filling system at zhangmatun iron mine is to adopt tailings after two stage dewatering from washing plant,make homogeneous grouting filling material with high density from mixing full tail sand,cement and water through stirring and form bulk and low grade grouting body with strong solidity,filling in gob taking pipe full self-flowing transport way.

马屯铁矿全尾砂胶结充填系统采用选矿厂两段脱水后的尾矿，通过搅拌将全尾砂与水泥、水混合制成高浓度均质胶结充填料，以管道全自流输送方式充入采空区，形成整体性强的大体积低标号胶结体。

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

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
