Biomechanical efficacy of calcium phosphate cement in augmentation and restoration of anterior cervical unicorti - cal screw fixation 磷酸钙骨水泥加固颈椎前路单皮质骨螺钉的生物力学研究
The transit of cement in bulk on yangtze river is a special new type of transit style that our country policy buoy and support hardly 长江散装水泥运输是国家政策积极鼓励和支持的特种新型运输方式。
Chapter five put forward some suggestions and countermeasures about the transit of the cement in bulk along yangtze rive 第五章在上述研究的基础上，结合个人近几年的实际运作，初步提出了发展长江散装水泥运输的有关建议和对策。
The influences of polymer on hydration of cement in mortar were analyzed by sem , and the mechanism of polymer modified mortar was discussed 通过扫描电子显微镜分析聚合物掺入到砂浆中对水泥水化的影响,探讨聚合物对砂浆的改性机理。
Success vision is a trading company offer ordinary portland cement in competitive price . we offer portland cement from top 5 manufacturers in china 成功的抱负，是一家贸易公司提供普通硅酸盐水泥在价格竞争。我们提供普通硅酸盐水泥，从五大厂商在中国。
Chapter three apply the basal concept and method of the " system theory and goods - flow theory " , and contrast the domestic transit of the cement hi bulk with the overseas , then point out the shortages of the transit in cement in bulk in our country 第三章从系统理论和物流理论的基本观念和方法，国内外散装水泥运输的对比分析，找出我国散装水泥运输存在的问题。
The conclusions are as follows : 1 . . the transit of cement in bulk along the yangtze river is one system project , the single department and unit are difficult to accomplish . ( the point have been not realized adequately in fact . ) 有一定参考价值的建议和结论如下： 1 、长江散装水泥运输是一项系统工程，单一的部门和单位难以完成该项工作(实际运输实务中认识这一点并不多) 。
2 the government should establish the lawmaking about the cement in bulk and the technique standard about the goods - flow system facilities , and research the allowable standards that how to engage the cement industry 2 、政府部门除抓紧制订有关散装水泥方面的立法工作外，还要着重研究水泥行业进入的许可标准和制定散装水泥物流系统设备设施的技术标准化等工武汉理工大学硕士学位论文作。
3 . the correlation of isotopic constitution and the relations between diagenesis and co2 indicate that co2 mainly derived from tertiary ca - mud rocks . the carbonate cements in reservoirs under the affection of hot fluid may form co2 , but the yield of co2 is low 基于碳酸盐矿物及本区浅层co _ 2的同位素组成对比分析，并结合浅部储层成岩作用与co _ 2的相互关系，认为co _ 2可能来自第三系钙质泥岩。
We started with a real strong foundation , we probably over engineered the foundation and poured a ton of cement in that foundation , and i know that it was effective and successful because there was an earthquake and this cabin was right on the epicenter 他找到解决所有问题的方法，我们有一个完善的计划，我们从一个稳固的根基开始，我们把根基建得实在稳固，灌了一吨混凝土在上面，我知道它十分稳固。
