The resulting phylogeny indicated that:(1) Araneidae and Tetragnathidae, which build orb webs, are not a sister group in the superfamily Araneoidea;(2) Theridiidae and Linyphiidae, which build nonorb webs, are also not monophyletic, The results also corroborated the independent origins of linyphiid sheet webs and theridiid gumfoot webs;(3) The phylogenetic placement of linyphiid closer to tetragnathid than to araneid implies that the similarities of male palpal organ between linyphiids and araneids may be homoplastic rather than homologous.

结果表明：(1)织圆网的园蛛科和肖蛸科蜘蛛在园蛛总科里不是姊妹群；(2)不织圆网的球蛛科和皿蛛科也不是单系的，进一步证实了皿蛛片网和球蛛网独立起源的观点；(3)皿蛛科蜘蛛的分子系统发生地位与肖蛸科较近而与园蛛科较远表明皿蛛科和园蛛科间雄性触肢结构的相似性很可能是类似而不是同源相似。

Based on the repetitive characteristic of the transmitted signal, a frequency domain signal model is developed. Its similarity to DOA estimation using an array and its ambiguity in parameter estimation are analyzed.

基于发射信号的周期重复性，建立了接收信号的频域模型，分析了该模型与利用阵列进行来波方向估计模型的相似性，以及该模型在参数估值时的模糊性。

One may need to entertain the hypothesis that based on the affinity between the network-like structure of comprehension and that of hypermedia products, intensive interaction with the latter might facilitate the construction of rather shallow associationist cognitive networks. Such networks would consist of trivial, frail connections, having no intellectual merit.

我们或许需要思考这一假设：由于意义理解的网络结构与超媒体产品的结构具有相似性，因此，学习者与超媒体产品的深入交互可能会促使学习者建立一种很肤浅的联想性的认知网络，这种网络之中所包含的是一些不甚重要的、虚弱的联系，而没有任何智慧的价值。

Its resemblance with the Assyrian hambakku, which is the name of a plant, is obvious.

其相似性与亚述人hambakku ，这是名称的植物，是显而易见的。

The results indicate that the effect of alloying elements V and Cr on mechanical properties at room-temperature, creep behavior and microstructures are similar. With increasing contents of V and Cr, their mechanical properties produce little change, the creep resistant property decreases and microstructure grows, which is mainly due to their characteristics of β-stability element and smaller atomic radius compared with Ti. On the contrary, the effects of V and Cr on the thermal stability are quite different. With increasing V content or decreasing Cr content the thermal stability for the alloy becomes better, which may be due to the different solution characteristics of V and Cr element in titanium alloy that V belongs to isomorphous β-stability element and Cr belongs to eutectoid β-stability element.

结果表明：合金元素V和Cr对Ti40合金室温力学性能、蠕变行为和组织的影响具有相似性，即随V和Cr含量的降低，合金室温综合力学性能变化不明显、抗蠕变能力减弱、组织粗化：这与V和Cr同属于β稳定元素、且原子半径都小于Ti原子有关；而V和Cr对于热稳定性能的影响则完全相反，V含量的增加或Cr含量的降低含金热稳定性能优化，其主要原因可能与V属于同品型β稳定元素而Cr属于共析型β稳定元素有关。

The thesis describes the autobiographic narrative from two aspects: First, fictitious world is the deformation from true world; Second, in Miranda serial novels, there is some resemblance between fictional world and true world. And the narrator and personage are the same only in the name.

本文从两个方面来论述小说的自传性叙事：一、亲自见闻性小说中的世界是真实世界的变形；二、"米兰达"系列小说中的虚构世界与真实世界的相似性以及叙述者与人物只是在名字上的同一。

The paper according to fractal autoregressive integrated moving average process models network self-similar traffic, estimates fractal dimension through fractal analysis methods directly and indirectly, and emphasizes on rescaled range analysis.

本文由分形自回归整合滑动平均流量模型产生自相似性数据。针对流量分形维数的求解，本文分别从直接估计和间接估计两个方面进行研究，采用分形分析方法对产生的业务流进行统计分析，其中重点讨论了变标度极差分析法。

The new algorithm satisfies four axioms of grey incidence and is consistent with the fundamental idea of curves similarity of grey incidence analysis.

理论推导证明该方法符合灰关联四公理，体现了灰关联分析中衡量曲线相似性的基本思想。

With researching in the particule social culture, tatoo convention, and the pattern's comparability between baldachin and tatoo of Li nationality, we think it is a kind of symbolic ceremony in fact. It is show the respect to the frog and woman of the Li nationality with totemic way.

通过对黎族独特的社会文化、文身习俗，以及文身图案与织锦图案的相似性等方面的研究，我们认为黎族妇女文身实际上是一种象征性的仪式，是用图腾的方式来表示对青蛙和黎族妇女的尊崇。

Image mining is the important branch of data mining.It is more than just an extension of data mining to image domain but an interdisciplinary endeavor.Image clustering and similarity retrieval are two basilic parts of image mining.

图像挖掘是数据挖掘的重要分支，它不仅仅是数据挖掘简单的扩展到图像领域，而是一个多学科交叉的研究方向周像的聚类和相似性搜索是图像挖掘的两个非常重要的领域。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
