无结构

Therefore, the structure could be stable. However, the structure was changed to amorphous when the strain level was over 15%. At the same time, the binding energy increased rapidly and the structure stability was reduced. During the deformation process, both the bond angle and bond length were significantly affected by the strain level.

这表明Ni纳米线的径向很软，结构之间几乎没有能量转换，且其稳定性基本不变；当压缩程度大于15%时，Ni纳米线结构变为无定形结构，它的结合能变大，且变化很快，表明其稳定性降低；压缩程度对Ni纳米线键角和键长的分布有着很大的影响。

Especially,the subbranch of enterobacteriaceace made again four small branches as genus taxon.This tree also shows that bacilliform bacterium is distinct from each other in the NJ and MP trees.After all species on the tree are merged,the topological configuration of the unrooted tree of 16S gene is closed to that of the host range unrooted tree.However,the position of bacillus is greatly changed on both the unrooted trees.

The results were expressed in mean±1SD. Pearson X~2 test and One-way ANOVA test were used. The data analyzed using the SPSS (version 11.5). Results: The sensitivity, specificity, positive and negative value of US for the LPEH model on the children cadaver were 88%, 84%, 79%, 91%, respectively. With regard to the thickness of femora head cartilage, the thickness of the anterior layer or posterior layer, there were no significant differences among three groups. However, the anterior layer was thicker than the posterior layer in three groups. The fluid in hip joint was detected in all of 21 symptomatic hips, which was clear commonly (90%) in early procedure. The amount of fluid in anterior recess showed a positive correlation with age (p .05). No fluid was detected in the asymptomatic and normal hips (2mm). The mean maximum width of inferomedial recess was significantly larger than that of anterior recess (12.50±4.04mm vs.4.35±0.8mm, p 0.05) in the symptomatic hip joints. The echogenic entrapped labral plicaes were demonstrated in the inferomedial recess in all of 21 children with LPEH, whose length and width ranged from 5.3mm-25.0mm (mean,15.6±5.6mm) and from 4.0mm-17.0mm (mean,8.9±7.8mm).

In this paper, as a typical lewis acid, anhydrous aluminum (AlCl_3) was used as the catalyst to get PP/PS blends compatibilized by in-situ Fridel-Crafts alkylation. The effects on PP and PS components of AlCl_3 were investigated first, mainly by rheology, including steady rheology method and dynamic rheology method. Then the in-situ reactions in PP/PS alloys under different conditions were executed and studied in detail by selective Soxhlet solvent extraction. And at the same time, the evolutions of phase structures of PP/PS and the resulted PP/PS/AlCl_3 alloys were investigated by SEM and SALS. The steady and dynamic rheological behaviors of in-situ compatibilized PP/PS alloys were obtained systematically.

through text analysis,this paper examines the syntactic and morphological means typically employed in introducing topics into chinese and english texts and their relations to discourse anaphora.we find that in both chinese and english the most important means for introducing the most important and accessible topics into discourse are the indefinite nps used as objects in existential-presentative sentences,and that the indefinite demonstrative adjective zheme and this can be used as an additional means to emphasize the importance of the entity introduced.however,the two languages differ in that,in english texts,apart from the above-mentioned linguistic devices,definite nps functioning as indirect objects and names functioning as subjects also tend to be used to introduce relatively important topics,and the emphatic one,in contrast to the indefinite article "a",can be used as another linguistic means to give additional emphasis on the relative importance of the topic introduced.

摘 要：本文以民间故事为语料，分析和研究了英汉篇章中话题引入的句法和形态手段及其与篇章回指的关系。我们发现，两种语言的主要相似之处为：1用作存现宾语的无定名词短语是引入篇章中最为重要和最为可及话题的主要手段；2英汉无定指示形容词this和&这么&可用于进一步强调所引入话题的重要性。两种语言最主要的差别是：1在汉语中，存现结构中的无定名词短语似乎是引入重要篇章话题的唯一形态句法手段；而在英语中，除此之外，用作间接宾语的有定名词短语和用作主语的专有名词也可以用于引入一个相对重要的篇章话题。2在英语篇章中，另有一个标示重要话题的附加手段，即以one代替a，以便进一步强调所引入话题的重要性。
