Several horizontal push - shear in - situ tests on srm in an immersion state under water were carried at long pan slope in tiger - leaping gorge , and some significant conclusions were drawn 摘要以虎跳峡龙蟠右岸地区分布的土石混合体为依托，对土石混合体在浸水条件下的力学响应进行了大型原位水平推剪试验，取得一些成果。
Their massive vaults , carried at both levels by monolithic columns of green and white marble and purple porphyry , serve as buttresses to receive the thrust of the great dome and its supporting arches 它们大块的拱顶，都擒带着同样等级的绿色和白色大理石和紫色斑岩的大块圆柱，作为支撑之用，受到了巨大的圆屋顶和它的支撑拱门的插入。
What s coming is a revolution . glass fibers will be able to carry at least 150 , 000 times as much information as the standard copper wires now used to connect the computer to a modem . an hour s worth of digital video will be delivered in seconds 然而要维持我们军队的最佳状态，就必须面对我一开始所提出的最后一项挑战：吸引并保持一支高水准且战技精良又能反映美国社会的志愿军。
Visit and read huang mr . " say good - bye to nationalism " articles on " the realms of thought " , discuss at heroes in terms of , discuss speeches send at great britain , ones that read if irritate and carry at spirit spirits , admire very much , connect down , collude some longs strongly fragrant thread of a conversation in the heart , wish to lend one of square treasured place here whitly , in order to teach in gaoming 于“思想的境界”上拜读到黄钟先生告别民族主义一文，雄谈快论，言议英发，读之如醍醐灌顶，十分佩服，接下来，勾起一些久郁在心中的话头，愿借此方宝地一白，以就教于高明。
It is approved that the deficiency level keeps relatively the lowest and the dielectric constant however shows the highest , if the contents of mn3 + and la3 + are comparatively the same . on the contrary , the dielectric constant decreases with increasing the contents difference of mn3 + and la3 + ions . the effect of overlap appeared when the dielectric loss was aroused due to the activation of positive and negative carries at certain temperature , which brought abnormally high dielectric loss 证实了材料在mn ~ ( 3 + )含量与la ~ ( 3 + )含量相当时体系中产生的缺陷相对最少，其介电常数最大，反之随两者含量偏差的增大而下降；材料中由正负两种局域载流子在一定温度下激活过程中产生的损耗出现了迭加效应，给出了异常的高损耗值;材料中随着mn掺量的增大，体系提供的3d电子数增多，电子输运通道改善，导电性提高。
Contemporary conflicts quite often occur with the employment of control - defying political , informational , network and other technologies which are not nominally a weapon but carry at the hands of their initiators no less devastating consequences for society and the individual and , as a consequence - for the integrity and sovereignty of states against which they are directed 双方认为，联合国因其权威性、普遍性和积累的独特经验，理应在保障国际和平与安全方面发挥协调作用。必须共同努力，建立一个以联合国为核心的应对新挑战与新威胁的普遍体系，以保障国际稳定、安全和可预见的发展。
