Application of ICHA cement in goat lateral tibial plateau compression fracture: The prevalence and degree of fracture subsidence was significantly reduced at the two time-points in the defects treated with ICHA cement compared with those filled with autograft. X-ray show the cement resorbed rapidly. There were no significantly differences in fracture stiffness between the two treatment groups at the two time-points.

ICHA水泥在羊外侧胫骨平台压缩性骨折中的应用：大体观察发现3个月和6个月两个时间点的自体骨组关节面出现塌陷的程度和数量均较骨水泥组严重。X光片示自体骨组3个月时已基本愈合，6个月时完全愈合，骨水泥组3个月时水泥被吸收分割成几块，边缘模糊，6个月时大部分吸收殆尽。

Portland cement was used as cementations materials in developing foamed concrete, and some high alumina cement and lithium salt were added into Portland cement to adjust the time of setting in order to match the stable time of foam.

以普通硅酸盐水泥作基材制备泡沫混凝土，为了与泡沫的稳定时间相匹配，研究采用在普通水泥中掺入一定量的高铝水泥和碳酸锂来调整水泥浆的凝结时间。

Portland cement, Alumina cement, Low cement castable

硅酸盐水泥，矾土水泥，低水泥浇注料

ABSTRACT Chemical corrosion mechanism of concrete in Qinghai salt lake is briefly reviewed, and bittern resisting behavior of high alumina cement concrete, magnesium oxychloride cement concrete, alkali-activated slag concrete, ferrialuminate cement concrete and polymer impregnated concrete are also reported in the paper.

摘 要 简述了普通水泥混凝土在盐湖环境中的受腐蚀机理﹔报道了高铝水泥、氯氧镁水泥、铁铝酸盐水泥、碱矿渣和聚合物浸渍混凝土的抗盐卤腐蚀行为﹔对硅灰高密实混凝土的抗盐卤腐蚀机理进行了详细讨论，认为改善孔结构是获取混凝土高抗腐蚀性的有效途径。

这些气 穴通常由具有格外高能量的水蒸气所填充，与混凝土表面的反复接触导致形成凹陷和孔洞，即气蚀。既然高质混凝土也不能抵抗这种劣化，因此最好的补救是通过制造平滑水流来消除气蚀。在所有必须的地方，关键的面上衬以高抗气蚀性的材料。通常，混凝土抗腐蚀和磨损的能力随强度增加而提高。采用硬韧的集料可改善混凝土的抗磨损性。

Cement kiln is used for making of cement clinker and there are dry and wet methods to make cement.

It is suggested that TDS can be used as a new method for the analysis of pedogenesis and climatic change.

总之，热处理过程中磁化率的变化能非常灵敏地反映磁性矿物的转化情况，而且，这种转化往往与样品所经历的土壤化作用强度密切相关，因此，TDS可做为分析成土作用强度和古气候变化的一种新方法。

Therefore, in this chapter, I will research into the conflict and contradiction of the paternity. Also, in this novel, the father's behavior of "He who loves well chastises well." is quite suspicious, one of the reasons is that the father thought his son belonged to him. And then, this thesis quoted Lacan's theory to touch upon that someone who has accepted the concept of patriarchal society, he will be influenced for his whole life. That also reveals that human being has no choice sometimes in this society.

因此本章会先就父子关系的冲突与矛盾做深入的探讨，小说中的父亲似有对儿子爱之深责之切的行为，其原因可能在於父亲将儿子视为所有物所致；其次，论文将引用拉冈相关理论，讨论在父权社会中，不论身分为何，只要是已受父权社会观念根深蒂固影响的人物，终生都将受其所苦，此也揭示出人生存於社会上的无奈。
