A series combined test method tests were performed to determine the liquid-plastic limits of different samples of fine grained soil and silty sand. The result showed that the loglog relationship between the depth of penetration of fall cone and the water content of some samples were clearly not linear, and the liquid-plastic limit could not be obtained according to the linear relation. Effective test data could not be measured within the three arranges of water contents proposed by the present standards. The dependability was necessary to discuss about the liquid-plastic limit test results obtained from three arranges.

采用液、塑限联合测定法针对部分细粒土和粉砂进行液、塑限测定时，发现对于部分细粒土在双对数坐标上圆锥下沉深度与含水率之间的关系并非线性关系，无法依据线性关系确定液、塑限：采用规程建议的三个含水率范围有时根本无法获得有效试验数据；采用规程建议的三个含水率范围确定得到土的液、塑限试验结果的可靠性有待商榷；采用直线段试验数据确定的液、塑限进行分类可能出现相互矛盾甚至错误的结果。

&在今后25年，艾滋病将和心脏病、中风一起并称为世界上三大头号致死疾病，而对身患AIDS的病人的治疗，至少可以挽救300万/年的生命，这一数字突出了艾滋病治疗的重要意义&，辉瑞制药代表Perros Manos认为，艾滋病可以被当作慢性疾病来治疗，按照现在的医药发展，患者每天仅吃一粒药就能得到救助，这比起以前每天吃十几粒药要更加有效且降低了药物对人体的副作用。

In General, the powder particle size large light reflector wide, rendering it has strong metal and white coloring, powder particle size is small, light reflector is narrow, rendering the authenticity of metallic weak.

一般来说，粉末粒径大的光反射面宽，呈现金属色的成色性强，粉末粒径小，光反射面就窄，呈现金属色的成色性就弱。

All metaphases showed three distinct green signals, which have the same size and intensity, corresponding to a normal chromosome 8 and two isochromosomes 8q, and five red signals, of which one was located on a normal chromosome 8 and the another two quite symmetrically on the both arms of each isochromosome 8q, respectively.

结果发现：所有中期分裂相均显示3个绿色荧光杂交信号和5个红色荧光杂交信号；2个绿色荧光杂交信号分别位于2条等臂8q染色体着丝粒处，信号大小和强度均与位于正常8号染色体着丝粒处的1个绿色荧光杂交信号相当；1个红色荧光杂交信号位于正常8号染色体长臂上，另外2个红色荧光杂交信号非常对称地位于每一条等臂8q染色体的两条长臂上。

The study of nature of the protoliths of metamorphic rocks in the Xingzi Group and their tectonic setting shows that the protoliths of mica schist, quartz schist and granulitite in metamorphic rocks of the Xingzi Group are sedimentary rocks.

提要：对星子群变质岩的原岩性质及其形成的构造环境研究表明，星子群变质岩中的片岩和变粒岩的原岩是沉积岩，其中云母片岩的原岩为粘土岩，石英片岩和变粒岩的原岩是杂砂岩或亚杂砂岩。

It is concluded that because the mica schist is mixed with feeble weathered granite, the grain is broken up severely; the back-analysis parameters of explosion rockfill(3BⅠ)are lower than the results of laboratory triaxial test, and the Duncan E-B parameters obtained by back-analysis of her sandy gravel (3BⅡ)are higher than the triaxial test results of laboratory triaxial test which can not reflect the mechanical behaviors of the dam material objectively; the research should be strengthened in 300 m high rockfill dam construction. The fitting modes of the space displacement field of prototype observation are also explored and it turns out that the results of IGA analysis considering only vertical deformation meet the need of dam's technical accuracy.

结果表明，由于在微弱风化花岗岩掺加云母片岩，颗粒破碎严重，爆破堆石料（3BⅠ）的原级配粗粒料反演参数远低于室内三轴试验成果；与3BⅠ堆石料相反，砂砾料（3BⅡ）现场反演得到的邓肯E~B模型参数高于室内三轴试验值；室内三轴试验成果不能客观反映筑坝材料的力学特性，对于当今的300 m级高土石坝建设，宜加强对原级配粗粒料的力学特性研究；同时对原型实测的空间位移场不同拟合方式进行了探讨，认为仅考虑铅直向变形的IGA参数反演成果能基本满足土石坝工程的精度要求。

For example, at the same content of nano-SiO〓, the average particle size of nano-SiO〓 treated with the silane coupling agent in ball mill was 97 nm, while the average particle size of nano-SiO〓 treated via ultrasonic dispersion reached 90nm.

在相同纳米SiO〓含量下，干法处理时，填料在基体中的平均粒径为97nm，一般湿法处理时，填料的分散粒径为90nm，硅烷偶联剂/分散剂复配处理所得填料在基体中分散效果最佳。
