以陕西某水泥厂立窑熟料为研究对象，利用偏光显微镜对水泥正常熟料、过烧和欠烧熟料进行了显微结构分析，揭示了水泥熟料显微结构与烧结过程中室内温度、通风、氧分布等烧结工艺的关系。

Under Multislice helical CT guidance, 2.5-5 mL of polymethylmethacrylate mixture （ratio of polymer, moner, ultrafluid iodinated oil was 20 g : 10 mL : 3 mL） had been injected into pathologic pedicles step by step after successful puncture using 13G needle.

在CT引导下，用13G针穿刺到椎弓根，将聚甲基丙烯酸甲酯粉剂、液态单体及超液态碘化油按20g：10mL：3mL的比例配制，当骨水泥呈膏状时，分步注入骨水泥约2.5～5mL。

In the invention, normal reversible absorbing transfer material for solar energy which are mixture of cobalt chloride and sextic methyl tetramine, phthalandione lipid compound and trilateral methane lactone compound, said material are produced to micro cachet that colour changes as stemp, changing reversely in normal temp, then said micro cachet are compounded with common white silicate cement to produce the invention cement base material.

本发明采用对太阳能呈常温可逆吸收转换材料：氯化钴与六次甲基四胺混合物、邻苯二甲酸酯类化合物和三芳甲烷内酯类化合物，将上述材料制成微胶囊，再将所制出的常温可逆温致变色微胶囊与普通白色硅酸盐水泥复合，即可制备出常温可逆温致变色水泥基材料。

This paper presents the influences of sulphonated naphthalene formaldehyde condensatesand sulphonated melamine formaldehyde condensatesused spearately,and compounded sperplassticiseron the slump flow loss for cement paste or mortar.and slump loss for high fluidity concrete.

本文详细研究了单独使用萘系高效减水剂FDN和三聚氰胺树脂系高效减水剂SM ，以及复合使用FDN +SM对水泥净浆和水泥胶砂扩展度，以及大流动性混凝土坍落度经时损失的影响。

The results show that one type of soft slurry occurs on the surface of mortar prism due to addition of limestone filler and a mass of thaumasite and gypsum forms in the slurry.

结果表明：掺石灰石粉使水泥砂浆受侵蚀后表面呈软泥状，主要腐蚀产物为硅灰石膏和石膏，表现为典型的TSA破坏特征，其强度损失率大于纯水泥砂浆。

In revision surgery an even higher incidence has been reported, ranging between 3.6% and 20.9% when cemented or uncemented prostheses are used, respectively.

翻修手术中报道的发生率更高，当应用骨水泥或非骨水泥假体时，其范围分别在3.6%至20.9%之间。

In reision surgery an een higher incidence has been reported, ranging between 3.6% and 20.9% when cemented or uncemented prostheses are used, respectiely.
